From 89633d1c20386f61e15074b05979547b953374a7 Mon Sep 17 00:00:00 2001 From: aXL333 <252040198+aXL333@users.noreply.github.com> Date: Wed, 22 Jul 2026 07:48:00 +0930 Subject: [PATCH 1/9] fix: close audit-critical safety and reliability gaps --- ...-2026-07-21-full-functional-qol-redteam.md | 180 +++++++++++++++ extension-liveweave/README.md | 2 +- extension-liveweave/background.js | 122 ++++++----- extension-liveweave/manifest.json | 2 +- extension-liveweave/mcp-client.js | 19 +- extension-liveweave/service-worker-state.mjs | 47 ++++ .../tests/service-worker-state.test.mjs | 32 +++ scripts/Test-ReleasePayload.ps1 | 11 + src/Foreman.App/App.xaml.cs | 70 ++++-- src/Foreman.App/ElevatedSidecarController.cs | 109 +++++++-- src/Foreman.App/GuardianControl.cs | 4 +- src/Foreman.App/Tray/TrayController.cs | 6 +- .../Windows/DashboardWindow.xaml.cs | 5 +- src/Foreman.App/Windows/SettingsView.xaml.cs | 14 +- src/Foreman.Core/ComputerUse/AdbBridge.cs | 39 +++- src/Foreman.Core/ComputerUse/CuBroker.cs | 25 +++ .../Events/BoundedEventHistory.cs | 42 ++++ src/Foreman.Core/Events/EventBus.cs | 8 +- src/Foreman.Core/Health/SidecarSupervisor.cs | 36 ++- .../Security/DecoyAuditOwnershipLease.cs | 60 +++++ src/Foreman.Core/Security/PresenceLock.cs | 6 +- src/Foreman.Core/Settings/SettingsStore.cs | 148 +++++++++++-- src/Foreman.EtwSidecar/DecoyAudit.cs | 206 +++++++++++++++--- .../GuardianInstallReference.cs | 84 +++++++ src/Foreman.Guardian/GuardianInstaller.cs | 10 +- src/Foreman.Guardian/GuardianIntegrity.cs | 41 ++-- src/Foreman.Guardian/Program.cs | 6 +- src/Foreman.McpServer/ForemanMcpTools.cs | 72 ++++-- src/Foreman.McpServer/ForemanState.cs | 25 ++- src/Foreman.McpServer/LiveWeaveBroker.cs | 24 +- .../SuspiciousCommandAlertLimiter.cs | 34 +++ .../ComputerUse/AdbBridgeTests.cs | 40 ++++ .../Events/EventBusTests.cs | 30 +++ .../Health/SidecarSupervisorTests.cs | 58 ++++- .../Security/DecoyAuditOwnershipLeaseTests.cs | 43 ++++ .../Security/PresenceLockPolicyTests.cs | 6 + .../Settings/SettingsStoreTests.cs | 51 ++++- .../GuardianIntegrityTests.cs | 18 +- tests/Foreman.McpServer.Tests/CuToolsTests.cs | 16 ++ .../ForemanMcpToolsTests.cs | 34 +++ .../ForemanStateTests.cs | 14 ++ .../LiveWeaveBrokerTests.cs | 9 +- .../PerHarnessTokenTests.cs | 10 + 43 files changed, 1575 insertions(+), 243 deletions(-) create mode 100644 docs/audit-2026-07-21-full-functional-qol-redteam.md create mode 100644 extension-liveweave/service-worker-state.mjs create mode 100644 extension-liveweave/tests/service-worker-state.test.mjs create mode 100644 src/Foreman.Core/Events/BoundedEventHistory.cs create mode 100644 src/Foreman.Core/Security/DecoyAuditOwnershipLease.cs create mode 100644 src/Foreman.Guardian/GuardianInstallReference.cs create mode 100644 src/Foreman.McpServer/SuspiciousCommandAlertLimiter.cs create mode 100644 tests/Foreman.Core.Tests/Security/DecoyAuditOwnershipLeaseTests.cs diff --git a/docs/audit-2026-07-21-full-functional-qol-redteam.md b/docs/audit-2026-07-21-full-functional-qol-redteam.md new file mode 100644 index 0000000..371622a --- /dev/null +++ b/docs/audit-2026-07-21-full-functional-qol-redteam.md @@ -0,0 +1,180 @@ +# Foreman Full Audit — Functional, QOL, and Red-Team (2026-07-21) + +**Snapshot:** commit `c5fd504` (merge of "complete bounded Android ADB bridge"). Independent second-opinion pass — Codex/GPT-5.6 already ran its own adversarial review while building the Build Week extension (see `docs/openai-build-week-2026.md`); this audit does not assume that review caught everything and does not defer to it. + +## 1. Executive Summary + +Foreman's foundational security engineering is genuinely strong: the MCP auth gate, the Vault's cryptography, the Guardian's per-connection caller verification, the decoy read-audit design, and the Desktop computer-use path (panic-stop checked before every single input, an independent hard floor, presence-gated approval that survives a stolen operator token) are all well-reasoned and mostly correctly implemented. But four **CRITICAL** gaps survive this pass, and three of them share a common root: **Foreman detects tampering in several places but does not consistently *act* on that detection** — a settings.json edit is flagged but never reverted, a Guardian install-time trust decision can be pointed at attacker-chosen input, and a flood of fabricated alerts can push a genuine Critical event off the operator's visible feed with no severity-aware protection. The fourth (only the sidecar's entry-point `.exe` is integrity-checked, not the DLLs it loads) undermines a defense the code believes is airtight. + +The newest code — the Android/ADB bridge — is the least mature relative to its own stated guarantees. Its core claim (no raw shell, allowlisted argument construction) holds up well under direct attack. But the scaffolding around it is incomplete: Settings changes never reach the running bridge (a revoked device stays live until restart — found independently three separate ways), Held Android actions can be approved with no presence tap (unlike Desktop), panic-stop can lose a narrow race, and the SHA-256 binary pin has a real, reproducible TOCTOU via NTFS junctions. + +None of this should block continuing to build — it should reprioritize the next work session. Section 8 gives a concrete order. + +## 2. Scope & Methodology + +**Coverage:** 11 subsystems, each deep-read by a dedicated agent: app composition/UI, core detection & repo scanning, decoys & presence, event-log integrity & setup health, MCP server surface, elevated ETW sidecar, Guardian watchdog, Vault, desktop computer-use, the new Android/ADB bridge, and monitor/platform/release pipeline. Five adversarial personas then hunted for chains crossing subsystem boundaries: a malicious MCP-authenticated harness, a same-user attacker never touching MCP, a build/release-pipeline attacker, a human-factors/alert-fatigue auditor, and a dedicated Android-bridge adversary. + +**What wasn't covered / was thin:** LiveWeave (extension-liveweave/) was excluded — it was Codex's actively-changing uncommitted work when this audit was scoped, then landed mid-run; it already has its own dedicated 37-finding review (2026-07-08). CuSidecar/CuPilot's own internals got secondary rather than primary attention (covered mainly through the Desktop CU comparison). Foreman.Platform/Linux was confirmed clean but only lightly read (small surface). + +**Prior audits on file:** a functionality audit (2026-06-17, 25 defects, mostly fixed), a security review (2026-06-16, 45 findings — its headline CRITICAL, a `FalsePositiveFilter` process-name-suppression bypass, is confirmed genuinely fixed, see §4.5), and the LiveWeave review (2026-07-08, 37 findings, addressed). This pass focused on what's new since: the Build Week hardening commit, and everything Android. + +**Verification:** every finding below carries the confidence the originating agent assigned (`confirmed` = read and traced firsthand; `likely`/`suspected` = strong circumstantial evidence, not fully traced). A second pass ran an adversarial verification panel over the raw pool — 14/15 sampled functional bugs were independently confirmed by a skeptical re-reader, and across ~43 security/attack-chain findings put through a 3-vote refutation panel, 103 of 129 individual votes (80%) did *not* refute the claim. **A script bug in the aggregation step crashed the run before individual verification verdicts could be attributed back to specific findings** — the raw pool below is what a human is reading, not a re-attributed "confirmed by panel" list. To compensate, I personally re-traced the two highest-blast-radius CRITICAL claims against the current code myself before including them (§4.1, §4.2) — both check out exactly as described, code-cited inline. + +## 3. Notable Strengths (read this too, not just the problems) + +- **MCP auth gate**: every `/mcp` request needs a valid bearer token; peer-PID binding and `CanMutate` fail closed consistently on token theft; per-harness tokens are HMAC-bound so one harness cannot forge another's identity. Applied thoroughly across nearly the entire tool surface, including the new `cu_*` tools. +- **Desktop computer-use path**: panic is checked before *every single SendInput* inside a gesture, backed by an independent hard floor (`CuDesktopPanicFloor`: BlockInput + release-all + TerminateProcess + a watchdog that can't leave the operator locked out), a three-gate sidecar handshake, independent result verification, and presence-gated approval that explicitly survives a stolen operator bearer token (INV-16). This is genuinely well-built and should be the template the Android path is brought up to. +- **Guardian's per-connection caller verification** (not the install-time trust question — see §4.2): every pipe connection is identified via kernel-level `GetNamedPipeClientProcessId` + `QueryFullProcessImageNameW` (unspoofable), and the SHA-256/signer check is recomputed on *every* connection, not just at install — confirmed fail-closed against a rebuilt dev binary by its own tests. +- **Vault cryptography**: AES-256-GCM with header-bound AAD, per-write random salt/nonce, reasonable Argon2id parameters, and a resolver that checks domain-binding before ever touching a secret. The locked-vault deposit queue's forgeability is explicitly and correctly documented as an accepted risk. +- **Android bridge's core argument-construction guarantee holds**: every verb builds a fixed `ArgumentList` template, integers are re-parsed/re-serialized (not blacklisted), `type` text passes a genuine allowlist excluding every shell metacharacter, and device serials are regex-constrained. No raw-shell escape was found anywhere. +- **Release pipeline payload validation genuinely works**: `Test-ReleasePayload.ps1` runs unconditionally before signing and fails the job on a mismatch; GitHub Actions are SHA-pinned throughout (an explicit, correct response to the 2026 actions-hijack incidents per `dependabot.yml`); fork PRs can't reach release secrets. +- **The 2026-06-16 CRITICAL (FalsePositiveFilter bypass) is genuinely fixed** — see §4.5 for the interesting nuance the fix produced. + +## 4. Critical Findings + +### 4.1 Settings-tamper detection never reverts, and arms everything before it even notifies (root cause, two blast radii) — **CONFIRMED, personally re-traced** + +`SettingsStore.Load()` computes a seal verdict but **always returns the settings object regardless** (`src/Foreman.Core/Settings/SettingsStore.cs:67`, verified: `return settings;` with no gate above it). The only reaction anywhere in the codebase is a single High `MonitoringNoticeEvent` fired at `App.xaml.cs:1020-1025` — well after PresenceLock, decoys, the Android bridge, and CU driver authority are already wired up from that same (possibly tampered) settings object earlier in `OnStartup`. There is no revert-to-last-known-sealed-values path anywhere. + +Two concrete consequences, found independently by two different passes: +- **Presence-lock bypass**: flip `PresenceLock.Enabled` to `false` in the plain-text, same-user-writable settings.json and every `PresenceGate.AuthorizeAsync` call silently no-ops for the whole session (`PresenceGate.cs:57-58`). +- **Android/ADB bridge hijack** (red-team, `local-non-admin-attacker` persona): set `AdbBridge.Enabled=true`, point `ExecutablePath` at an attacker binary, and set `ExecutableSha256` to that *same* binary's own hash — the "pin" is self-consistent by construction since the attacker controls both fields. The bridge arms with an attacker binary, and the next legitimately-authorized harness action runs it with Foreman's own trust against a real enrolled phone. The same unconditional-load bug also seeds `CuDriver` from settings with no presence gate (`App.xaml.cs:314`). + +This also directly contradicts `SettingsSeal.cs`'s own doc comment, which claims tampering "can be reverted + alerted" and that there is "a SACL write-audit on settings.json" — neither exists in code. + +**Fix direction:** check `SettingsStore.LastSealVerdict` *before* wiring any security-relevant subsystem, and on `Tampered`, fail closed on those specific fields (re-apply last-known-sealed values) rather than arming first and notifying second. + +### 4.2 Guardian's install-time trust decision can be pointed at attacker-chosen input — **CONFIRMED, personally re-traced** + +`Foreman.Guardian.exe --install --foreman ` passes that path through with **zero validation** (`Program.cs:27`, `ArgValue("--foreman")`). `GuardianIntegrity.Decide()` (`GuardianIntegrity.cs:30-38`, read directly): + +```csharp +if (referenceSigner is null) + return (true, "reference binary is unsigned (dev build) — signature not enforced."); +``` + +— returns `Trusted=true` **unconditionally** whenever the reference is unsigned, without even inspecting the subject signer in that branch. An attacker needs no cert theft — just `--foreman `. `GuardianClientPolicy.CreateForInstall` then **persists** that same attacker-chosen path + hash into `client-policy.json` as the one caller permanently authorized to talk to the elevated, SYSTEM-service Guardian. Exploitation requires the attacker to trigger their own `ShellExecute("runas", ...)` with a forged `--foreman` argument — one UAC prompt for "Foreman.Guardian.exe," a prompt shape Foreman routinely and legitimately asks users to approve elsewhere, priming acceptance. + +**Fix direction:** never trust `--foreman` as attacker-suppliable input for a security decision — resolve the reference path independently (invoking process's own verified identity, or a known-install-dir lookup). Separately, `Decide()`'s unsigned-reference branch should not exist as an unconditional-trust shortcut at all. + +### 4.3 Unrestricted `report_suspicious_command` flood can evict genuine Critical/High alerts from every operator-visible surface — **confirmed** (subsystem + malicious-harness persona, converging independently) + +Any connected harness — even one that fails `CanMutate` — can call `report_suspicious_command` in a tight loop with fabricated `commandLine` text engineered to match a Critical rule; the text is never executed, only pattern-matched, and there is **no rate limit and no `CanMutate` gate** on the base publish (`ForemanMcpTools.cs:304-369`). Every subsystem's alarms (settings tamper, decoy tripwire, log-anchor rollback, sidecar impersonation, Guardian issues) funnel through the *same* `EventBus`, whose history is a plain 1000-item FIFO with **zero severity weighting** (`EventBus.cs`), and `ForemanState`'s alert store evicts the same way. `DashboardWindow`'s live feed further only shows the 50 most recent by timestamp — as few as ~50 flood calls push any older alert, regardless of severity, entirely off screen. `foreman_health`'s green/amber/red status derives from the same evictable store, so it can report green moments after a genuine, still-unresolved Critical fired. + +**Fix direction:** per-caller rate limiting at the MCP auth gate covering every tool (not just CuBroker); require `CanMutate` for the base publish; make both eviction policies severity-weighted (never evict an unacknowledged High/Critical ahead of older noise); give the dashboard feed a pinned unacknowledged-Critical/High section immune to `Take(50)`. + +### 4.4 Only the sidecar's entry-point `.exe` is integrity-checked and pinned — its DLLs are not — **confirmed** + +`SidecarPath()` and `PinBinaryAtRest()` (`ElevatedSidecarController.cs`) name and lock only `sidecar\Foreman.EtwSidecar.exe`. `Foreman.App.csproj`'s `CopyEtwSidecar` target copies the **entire** build output tree into that same folder — confirmed against the actual build: `Foreman.EtwSidecar.dll` (the real managed payload the signed apphost loads via hostfxr/coreclr with no signature check of its own), `Foreman.Core.dll`, and ~10 other same-user-writable dependency DLLs sit completely unprotected next to the pinned exe. A same-user process that overwrites `Foreman.EtwSidecar.dll` gets its own code executed under the admin token the branded UAC prompt grants — neither defense notices. + +**Fix direction:** publish the sidecar self-contained + `PublishSingleFile` so all managed code embeds into the one already-checked PE, or extend both the pin and the integrity check to every file under `sidecar\`. + +## 5. High Findings + +*(Confidence noted; "×N" marks a finding independently reached by N different agents/personas — treat as higher-confidence.)* + +- **Android Held actions need only the operator bearer token to approve — no presence tap, unlike Desktop** (`ForemanMcpTools.cs` CuApprove, `App.xaml.cs`). Desktop's INV-16 explicitly survives a stolen operator token; Android's does not — a live security regression relative to the codebase's own stated invariant, on the flagship new feature. *confirmed* +- **Panic-stop can lose a narrow race on Android**: `AdbBridgeExecutor` never checks a halted signal inside its own two-sequential-adb-call sequence (get-state, then the real command); if panic fires in the gap between calls, the state-changing command still runs. Distinct from the already-known batch-loop gap. *confirmed* +- **adb.exe SHA-256 pin has a real, empirically-reproduced TOCTOU via NTFS junctions** ×3 (subsystem + android-focused persona + malicious-harness persona chained into zero-interaction code execution via `cu_status` leaking the exact path). The pin is checked once at construction; every launch re-resolves the path string, and a same-user process can junction-swap the containing directory (no special privilege) to redirect every subsequent launch. *confirmed* +- **Android/ADB bridge Settings changes never reach the running broker/executor** ×3 (app-composition-ui, android-adb-bridge subsystem, android-focused persona spot-check — flagged as "still open" from a prior review). Disabling the bridge or un-enrolling a suspected-compromised device gives a plain "Saved" confirmation while the live bridge keeps honoring the old state until a full restart. *confirmed* +- **WMI creation watcher can fully miss a process that starts and exits inside its ~1s poll window** — no compensating discovery exists; a fast one-shot dangerous command from an adversarial harness can evade command-line heuristics, cred-sweep, and orphan tracking entirely, not just with added latency. *confirmed/likely* +- **Guardian's Authenticode gate never checks certificate revocation** (`WTD_REVOKE_NONE`), both for the runtime publisher check and the install-time LPE self-verify — a revoked signing key is trusted forever. *confirmed* +- **`OsEventLogAvailable` is computed once at construction and never updated** — if OS-log writes start silently failing later (log full, service stopped, or a same-user flood of the Application channel), Setup Health keeps showing green for the rest of the session even though the external anti-rollback witness has gone dark. *confirmed* +- **The external log anchor is only republished at launch/rewrite/rotate/clean-exit, not per-append** — a quiet, long-running session's entire forward progress is covered only by the same-user-forgeable in-file chain; a snapshot-then-restore attack reads as "honest forward progress," not rollback. *likely* +- **Vault's presence prompt never names the origin**, contradicting its own "informed consent / anti-phishing" doc comment — the Windows Hello dialog for a credential release or self-signup reads as generic "Authorize a Foreman security change" with no site named. *confirmed* +- **Decoy tripwire only audits `ReadData`** — deleting or overwriting a bait file is an ordinary same-user file op that permanently and silently blinds it, and `Revalidate()` reclassifies this as benign "reclaimed for real credentials" with no alert. *confirmed* +- **CuBroker's Held-item store grows unbounded** — a throttled or Android-forced-Held submission is never pruned; a CU-driver-authorized harness (a normal config, not a bypass) can OOM-crash `Foreman.App` itself, and nothing relaunches it. *confirmed/likely* +- **Auto-approved `logcat` gets zero pre-execution scrutiny and leaves zero durable trace** — no Android case in the fast-path heuristics, a default confidence-1.0 Allow that never escalates to deep judge, an unfiltered device-wide dump, and no EventBus publish for any executed observe-only action. *confirmed* +- **Temporal-anomaly tagging false-positives "monotonic-clock-regressed" on almost every restart** — the write-time check lacks the session-boundary gate its own read-time `Verify()` equivalent has. *confirmed* +- **The auditpol-ownership marker has no ACL hardening**, trusted on bare `File.Exists` — a same-user process can forge or erase it, making Foreman wrongly enable or disable a machine-wide audit policy it never owned. Notably, the sibling Guardian `ProgramData` folder *is* correctly hardened — the team knows the pattern, just didn't apply it here. *likely* +- **Release workflow installs Inno Setup via unpinned Chocolatey** immediately before building the installer that signing and attestation subsequently validate — every other tool in the same workflow is SHA-pinned per the project's own stated rationale; this one isn't, and a compromise here would be validly signed and truthfully attested (attestation proves *this workflow* built it, not that the build tool was clean). *likely* + +## 6. Medium Findings + +- `FalsePositiveFilter`'s process-name suppression is now **dead code** — the 2026-06-16 CRITICAL fix gated it to severity < Medium, but all 88 current rules are Medium+. Its `Info` fail-open default plus no load-time severity validation means a future rule with a *misspelled* severity string would silently reopen the identical bypass shape (`PatternRule.cs`). +- `ScanRepoForAgentConfig` is the one MCP tool with **no CallerScope check at all** — any authenticated (including narrowly-scoped) harness can scan an arbitrary absolute path. +- Launcher-hygiene suppression marker is unanchored to the actually-invoked script — a decoy substring anywhere in the raw command line can suppress a real `win-002` PowerShell-bypass alert. +- `VaultResolver`'s three distinct failure-reason strings ("not found" / "wrong origin" / "not authorized") let a caller distinguish "credential exists" from "doesn't," contradicting its own documented no-existence-oracle guarantee. +- `KillGuard`'s never-kill set was never extended to the two new Build Week executables (`Foreman.CuSidecar.exe`, `Foreman.CuPilot.exe`). +- A failed Guardian upgrade can strand a rolled-back service pinned to the wrong Foreman hash (policy file is written before the point of no return, and isn't rolled back with the binary on failure). +- Guardian's publisher-signed pinning is tied to an exact certificate **thumbprint**, not a renewal-stable identity — the first legitimate cert renewal (once signing ships) breaks every subsequent release until a manual re-pin. +- Guardian's pipe is single-instance with no per-request timeout — any same-publisher-signed caller can permanently wedge it, silently downgrading every future caller to the unprotected local path. +- The `SealSettings` wire protocol has presence-gated "weakening action" fields that are **implemented on neither end** — the SYSTEM guardian adds no independent check for this operation beyond client identity. +- SetupHealth has **no row at all** for the event-log integrity subsystem's own state (Verify()/AnchorPolicy outcome) — a rollback/forgery notice detected at boot leaves no persistent trace on the one screen meant to answer "is everything OK." +- Setup Health tab can freeze the WPF UI thread for up to ~2.5s when the Guardian pipe is slow (synchronous IPC on the UI thread). +- The android-bridge's device-enrollment membership check is case-insensitive, but the raw caller-supplied casing (not the canonical enrolled value) is what's actually forwarded to `adb -s`. +- `CuBroker.Claim()` never re-validates Android device enrollment at delivery time, unlike Desktop/Browser's explicit re-gate blocks; and `cu_complete_action` isn't modality-scoped like `cu_poll_actions` is, letting a browser-scoped identity race-overwrite an in-flight Android action's recorded outcome. +- The TOCTOU-vulnerable decoy-paths handoff to the elevated sidecar is a plaintext temp file with no path validation, in a window bounded by UAC-approval latency. +- CODE_SIGNING.md — the doc specifically about verifying a download — never mentions `gh attestation verify`, the one check an attacker who merely controls the distribution channel can't forge. +- `release.yml` has no guard preventing an already-published version tag's assets from being silently rebuilt from a different commit. +- `CuStatus` and `CuBroker.CanDrive` have two smaller scoping gaps: the adb executable path/enrolled serials leak to any caller, and a harness literally named `"operator"` would get unconditional driver authority (currently dormant — no minting path produces that id today). +- Broker post-panic bookkeeping can mislabel a completed Android action as "Rejected — halted by panic" when it actually ran to completion on the phone. +- CU approval cards render every modality identically — the one on-screen hint ("a desktop action also needs a Windows Hello tap") implies Desktop is the *stricter* case, when Android/Browser get zero presence verification at all; the status text says "complete any Hello prompt" even for rows where no prompt will ever fire. +- A Held computer-use action produces **zero passive signal** anywhere in the app (no toast, no tray-color change, no tab badge) — the only way to notice one is to proactively open Approvals. +- Toast notifications title any `Severity.High` event "Critical Alert" — identical wording to a genuine Critical, diluting the word before the operator decides whether to open it. +- Game Mode **ships enabled by default** with `AllowCriticalBreakThrough=false` by default — every severity, including Critical, is silently withheld for the duration of any fullscreen/presentation state unless the operator finds an indented, unchecked sub-checkbox. + +## 7. Low Findings (terse) + +- `PatternRule.FalsePositiveTags` is parsed from every rule but consulted nowhere — vestigial. +- `data/patterns/*.json` has silently drifted out of sync with the live `src/Foreman.Core/patterns/*.json`, contradicting `CONTRIBUTING.md`'s sync instruction; dead and unenforced. +- Dashboard's Settings tab is the only tab never refreshed on tab-show, making `SettingsView.RefreshState()` dead code. +- `App.OnExit` never disposes the desktop-CU sidecar controller or pilot-channel controller (mitigated by their own parent-exit polling — not an orphan-process bug in practice). +- `actions/upload-artifact` is still pinned to a node20-runtime release while sibling actions were bumped to node24 (dormant until signing is enabled). +- `HarnessClassifier` is pure exe-basename matching with no path/hash check — a renamed harness silently loses classification (likely an accepted trade-off; the project explicitly avoids hardcoded binary rosters elsewhere). +- Decoy read-audit's `ExpectedReaders` allowlist is dead code for 7 of 8 canonical decoy kinds (only `.npmrc` is ever actually SACL'd). +- No operator signal when tracked-decoy coverage silently shrinks (`Revalidate()` only runs from the Settings-save handler). +- Decoy watcher starts *after* the SACL ACE goes live — events in that startup gap are lost, never backfilled. +- SetupHealth shows green "Ok" for decoy read-auditing despite its own code comment admitting a connected sidecar doesn't prove events are actually flowing. +- No on-device smoke test exercises the Android bridge's approve→execute→panic chain the way the Desktop path has one. +- `SseSessionManager.MatchesHarness` is documented "never for authorization" but is used exactly that way (low impact: only name/version/capability-flags exposed). +- No operator signal when the Held CU queue balloons from a throttled/misbehaving driver. +- `ReportSuspiciousCommand`'s free-text parameters have no length cap, unlike every other free-text MCP parameter in the file (not exploitable — regex timeouts bound it — just an inconsistency). +- CU approval card's argument preview truncates at 240 characters in low-contrast styling with no "view full" affordance. + +## 8. Attack Chains (the distinctive red-team output — narrative, not a checklist) + +**The settings-tamper-to-ADB-hijack chain** (§4.1 root cause, Android consequence) is the sharpest: an attacker who never touches Foreman's MCP server at all — just a plain-text edit to a file their own user account already owns — can arm the Android bridge with their own binary, self-consistently "pinned," and have Foreman's own elevated trust launch it against a real enrolled phone the next time *any* legitimately-authorized harness issues an ordinary approved action. The tamper notice fires, but only after the bridge is already armed, once per session, dismissible. + +**The vault-memory chain** (same persona): the master password and every decrypted secret sit as plain managed `System.String`/`byte[]` in `Foreman.App`'s own process memory for the whole unlocked session — `VaultDocument.cs`'s own doc comment already admits this is an open limitation. A co-resident, unprivileged process needs nothing more than Task Manager's built-in "Create dump file" to string-scan past the AES-256-GCM+Argon2id+DPAPI envelope entirely, because none of that protects data already decrypted and resident in the reader's own accessible memory. + +**The Android zero-interaction RCE chain** (malicious-MCP-harness persona): `cu_status` leaks the exact `adb.exe` path to any caller with no gate → the junction-swap TOCTOU (§5) redirects it → a *read-only, observe-only* Android verb like `screenshot` (which skips the Held/approval gate entirely, by design, because it's "just observation") auto-executes the swapped binary as a child of `Foreman.App` itself. The payload then runs outside every AI-harness process tree Foreman's own command-heuristic/WMI monitoring polices, laundering execution through — and evading — the tool meant to catch exactly this. Three independent things had to individually be true for this chain to close (leak, TOCTOU, observe-only-skips-gating) — each is fixable alone, and any one fix breaks the chain. + +**The alert-flood-to-blackout chain** (§4.3, extended): the same unthrottled `report_suspicious_command` flood that evicts alerts can, via `cu_submit`'s unbounded Held-item accumulation, escalate to OOM-crashing `Foreman.App` entirely — taking down the tray, the MCP server, and the sidecar supervisor with it, with no Guardian auto-relaunch. An attacker inside Foreman's own mediation surface, using only documented tools, can produce an unattended, indefinite monitoring blackout. + +**The build-pipeline chain** (supply-chain persona): unpinned Chocolatey → unverified Inno Setup compiler output → validly SignPath-signed (SignPath signs bytes, not intent) → checksums generated over the same tampered bytes → attestation truthfully proving *this compromised workflow run* built it. Every documented verification mechanism can be individually satisfied by a compromise that happens upstream of all of them. + +**The human-factors chain** (operator-coercion persona): CU approval cards render every modality identically, with copy that specifically calls out Desktop's presence tap and says nothing about Android/Browser having none; the status line says "complete any Hello prompt" even when no prompt will fire; a Held item generates zero passive signal until the operator proactively opens Approvals; and Game Mode ships on by default, silently withholding even Critical alerts during any fullscreen state. None of these require a code exploit — they compound into exactly the rubber-stamping conditions a real attacker (or a rushed operator) would want. + +## 9. Prioritized Fix Plan + +**P0 — before any further public/judged exposure:** +1. Settings-tamper fail-closed (§4.1) — *medium effort*, highest leverage: closes the presence-lock bypass and the ADB-hijack chain in one fix. +2. Guardian install-time trust bypass (§4.2) — *small effort*: stop trusting `--foreman` as attacker input. +3. `report_suspicious_command` rate-limit + severity-weighted eviction (§4.3) — *medium effort*. +4.

Remediation follow-up (2026-07-22) + +The original findings above describe snapshot `c5fd504` and are retained as the audit record. The following fixes were applied in the subsequent working tree and regression-tested before hand-off: + +- **Settings tamper now fails closed before composition.** `SettingsStore.Load()` never returns a settings object whose security projection failed its seal. It restores a separately sealed last-known-good snapshot before `App.OnStartup` wires any subsystem, quarantines the attempted file, and uses safe defaults when no verified recovery exists. +- **Guardian install no longer trusts a `--foreman` path.** The app passes only its live PID; the elevated Guardian resolves that process image itself and requires its own executable to occupy the canonical sibling `guardian` directory. Signed releases still require matching verified publishers. Unsigned development remains usable only through this live-launcher/layout route, rather than an unconditional unsigned-reference pass. +- **Suspicious-command alert minting is bounded.** Verdicts remain available to callers, but operator-visible publication now requires a mutation-capable (non-peer-mismatched) caller and is capped per caller. The EventBus and MCP alert store evict acknowledged/lower-severity noise before unresolved High/Critical evidence, and the dashboard pins unresolved High/Critical cards ahead of ordinary recency. +- **Elevated sidecar payload integrity is complete.** Shipped builds were already published as one self-contained signed executable; release validation now explicitly rejects any neighbouring sidecar payload. Framework-dependent development builds now hold write/delete-denying handles on every staged sidecar file and verify the directory snapshot before elevation, rather than locking only the apphost EXE. +- **Android Held approvals have presence parity.** Both MCP and in-app approval paths require a fresh Hello/FIDO2 verification for Held Android actions, matching Desktop's bearer-token-resistant approval rule. +- **ADB junction redirection and panic-gap paths are closed.** `AdbProcessRunner` launches the final path resolved from the already hash-checked, pinned file handle, so swapping a parent junction cannot redirect `Process.Start`. The executor also re-checks panic after `get-state` and immediately before the device action. +- **ADB configuration changes apply live.** Save now revokes all non-terminal Android actions, clears device authority, stops/disposes the old pump and binary lease, then arms the newly saved binary/device set. Disabling or un-enrolling therefore takes effect before the Settings view reports success; stale approved actions must be re-submitted. + +The auditpol ownership-marker High finding was also addressed in the same working tree with a short-lived, ACL-hardened, atomically written ownership lease and ownership-safe rollback/disable behaviour. diff --git a/extension-liveweave/README.md b/extension-liveweave/README.md index 13628c8..dd96570 100644 --- a/extension-liveweave/README.md +++ b/extension-liveweave/README.md @@ -1,6 +1,6 @@ # Foreman LiveWeave browser extension -LiveWeave 0.4.1 is a Manifest V3 visual website workspace linked to the local Foreman desktop app over loopback.

The round-two fix anchors the root in HKLM and requires a loud `--allow-unsigned-development` opt-in; unsigned shipping installs fail closed by default. - **Suspicious-command alert minting is bounded.** Verdicts remain available to callers, but operator-visible publication now requires a mutation-capable (non-peer-mismatched) caller and is capped per caller. The EventBus and MCP alert store evict acknowledged/lower-severity noise before unresolved High/Critical evidence, and the dashboard pins unresolved High/Critical cards ahead of ordinary recency. - **Elevated sidecar payload integrity is complete.** Shipped builds were already published as one self-contained signed executable; release validation now explicitly rejects any neighbouring sidecar payload. Framework-dependent development builds now hold write/delete-denying handles on every staged sidecar file and verify the directory snapshot before elevation, rather than locking only the apphost EXE. - **Android Held approvals have presence parity.** Both MCP and in-app approval paths require a fresh Hello/FIDO2 verification for Held Android actions, matching Desktop's bearer-token-resistant approval rule. diff --git a/docs/audit-2026-07-22-round2-fix-verification.md b/docs/audit-2026-07-22-round2-fix-verification.md new file mode 100644 index 0000000..596a3b2 --- /dev/null +++ b/docs/audit-2026-07-22-round2-fix-verification.md @@ -0,0 +1,229 @@ +# Round 2 Fix-Verification Audit: Foreman + +**Subject:** commit `89633d1` "fix: close audit-critical safety and reliability gaps" (~1,053 insertions, 35 files, 5 new classes) +**Baseline audited:** `c5fd504` (report at `docs/audit-2026-07-21-full-functional-qol-redteam.md`) +**Scope:** Does the fix pass actually hold?

Executive Summary + +The fix pass is real engineering, not test theater, but it did not close the four CRITICALs. It closed each one **on the exact path the original audit described and on the path the new tests exercise**, then left a sibling path open. That is the most dangerous failure mode for a round-2 patch, because a finding that changes code, adds a green test, and still leaves a bypass gets **retired** in the tracker while the exploit still works. Of the four CRITICALs: C2 (Guardian trust) is effectively **not fixed** for the shipping unsigned reality; C1, C3, and C4 are each **PARTIAL**, with a one-step bypass that is quieter or worse than the pre-fix behavior. The genuinely strong work is in the Android/ADB cluster (four of five items are SOLID and one, the adb junction TOCTOU, was empirically defeated on-box and held) and in the mechanical soundness of the decoy marker ACL check, the alert-limiter's `CanMutate` gate, and the release-payload single-file assertion. + +Two things push this below a clean pass. First, the seal-deletion bypass: deleting one same-user-owned file (`settings.json.seal`) turns the entire C1 tamper-revert into a silent no-op, and it was found independently by two separate red-team passes. Second, the pass introduced **regressions**: a sidecar-supervisor state that wedges into a permanent silent monitoring blackout, and a tamper-revert that destroys the operator's entire settings file on a documented `mcp.token` rotation. For a 1,053-line security patch, having live regressions in the recovery paths is the headline concern. + +### Verdict distribution + +| Cluster | Original severity | Verdict | +|---|---|---| +| C1 settings-tamper (§4.1) | CRITICAL | **PARTIAL** | +| C2 guardian-trust (§4.2) | CRITICAL | **INEFFECTIVE** | +| C3 alert-flood (§4.3) | CRITICAL | **PARTIAL** | +| C4 sidecar-DLLs (§4.4) | CRITICAL | **PARTIAL** | +| H android/ADB cluster | HIGH | **PARTIAL** (4 of 5 items SOLID) | +| H decoy-auditpol | HIGH | **PARTIAL** | +| H misc cluster | HIGH | **PARTIAL** | + +Confirmed survivors after adversarial refutation: **3 CRITICAL, ~16 HIGH**, plus mediums/lows and **9 regressions** the fix pass introduced. + +--- + +## 2.

Deleting `settings.json.seal` silently adopts the tampered settings file (C1 bypass) +Found independently by two red-team passes. +- **Where:** `SettingsStore.cs:206-210` (`ReadSeal` returns null on missing file) → `SettingsSeal.cs:125` (empty seal maps to `Unsealed`) → `SettingsStore.cs:68/74` branch only on `Sealed`/`Tampered`, so `Unsealed` falls through to `return settings;` at `:93` with `LastLoadFault` null. No consumer of `LastSealVerdict` reacts to `Unsealed`: `App.xaml.cs:1039` publishes on `Tampered`, `:1050` on `Unverified`, nothing on `Unsealed`. `Core/Health/SetupHealth.cs` has no sealing check. +- **Failure scenario:** A same-user agent sets `PresenceLock.Enabled=false`, `AdbBridge.Enabled=true`, `ExecutablePath=C:\evil\adb.exe` with a self-consistent hash, then `del %LOCALAPPDATA%\Foreman\settings.json.seal`. Next launch: `PresenceGuard.Configure` (`App.xaml.cs:982`) gates nothing (`PresenceLock.cs:95`), `ApplyAdbState` (`App.xaml.cs:378-416`) arms the bridge with the attacker binary, no alert fires. The first subsequent `Save` re-seals the attacker posture as legitimate. The sealed `.lastgood` snapshot that would have caught this (`SettingsStore.cs:133-134`) is read only inside the `Tampered` branch, never when the seal is simply absent, even though "`.lastgood`+`.lastgood.seal` present but `settings.json.seal` absent" is an unambiguous deletion signature. +- **Why it matters:** This reproduces both original C1 blast radii (presence lock no-opped, ADB bridge armed with an attacker binary) with **less** noise than before the fix, and it retires the finding. +- **Fix direction:** Treat "no primary seal but a verifiable `.lastgood`/`.lastgood.seal` pair exists" as `Tampered`. Persist a durable "this install has been sealed" bit outside `settings.json` (guardian-side or OS event log) so the no-seal path cannot be re-entered on demand. + +#### CRITICAL-2. Attacker fully controls the "canonical staged layout" proof (C2, original §4.2 still open) +- **Where:** `GuardianInstallReference.cs:39` checks only leaf name `Foreman.exe`; `:51-58` compares the guardian's own path against a directory derived from that same attacker-supplied process. `GuardianIntegrity.cs:55-60` returns `Trusted=true` when `referenceSigner` is null, `trustedDevelopmentLayout` is the hardcoded literal `true` (`GuardianInstaller.cs:47`), and `subjectSigner` is null (releases are currently unsigned). `GuardianInstaller.cs:54/77` persists `ForemanPath=`+SHA-256 as the sole authorized guardian caller. +- **Working chain (medium-IL, same user):** `mkdir %LOCALAPPDATA%\x`; copy payload to `x\Foreman.exe`; run it → PID P (satisfies leaf-name check). Copy the genuine guardian dir to `x\guardian\` (satisfies `:51-58`, because `expectedGuardian` is computed from the attacker's own step-1 path). `ShellExecute("runas", "x\guardian\Foreman.Guardian.exe", "--install --foreman-pid P")`. Cost went from "one CLI argument" to "one CLI argument plus two file copies." +- **Blast radius:** The pinned client is the only gate on the guardian pipe (`GuardianPipeServer.cs:76`); a trusted client can call `SealHead` (`:109-117`) and `SealSettings` (`:132-143`). A successful re-pin lets the attacker mint SYSTEM-key seals over an arbitrary event-log head and arbitrary settings projection, which **undercuts the C1 fix in the same commit** (that fix restores/validates a *sealed* snapshot). +- **No anchor exists:** `installer/foreman.iss:24-25` installs per-user to `{localappdata}` with `PrivilegesRequired=lowest`. There is no non-user-writable location for the layout to be canonical against. The commit's own remediation note (`docs/audit-2026-07-21-full-functional-qol-redteam.md:173`) asserts the stronger, false property "Unsigned development remains usable only through this live-launcher/layout route." +- **Fix direction:** Record the install root under HKLM during the elevated install; require the resolved launcher to match it. Bind the launcher PID to this process. Make the unsigned branch an explicit, loud `--allow-unsigned-development` opt-in so shipped-but-unsigned builds fail closed. + +#### CRITICAL-3. Attacker-minted Critical alerts invert the severity policy; genuine High is dropped on arrival (C3) +- **Where:** `ForemanMcpTools.cs:372` publishes `match.Severity` verbatim, and `src/Foreman.Core/patterns/dangerous-commands.json` rules `del-001..del-006` are `"severity":"critical"` and match text that is only pattern-matched, never executed (e.g. a string containing `rm -rf /`). `BoundedEventHistory.Add` appends the new event (`:25`) then picks the victim as the global minimum of `(Acknowledged?0:1, Severity, Timestamp)` over a list that **includes** the just-added item (`:28-34`). `ForemanState.OnEvent` does the same (`:112-127`). +- **Failure scenario:** After ~1,000 unacknowledged Critical items are resident (~83 min at 12/min for one harness identity, then self-sustaining with zero further traffic), an arriving genuine **High** (severity 3) is the global minimum and is evicted immediately. It never reaches `EventBus` history (dashboard feed, `DashboardWindow.xaml.cs:237`), `get_events` (`ForemanState.cs:243`), or the ackable store. Pre-fix FIFO retained that High for 1,000 more events. Most of Foreman's own self-protection alarms are High, not Critical: settings tamper (`App.xaml.cs:1041`), sidecar impersonation (`DesktopCuController.cs:178`), log integrity (`App.xaml.cs:250/268/1105`), MCP down (`App.xaml.cs:1432`), tool-scan findings (`McpToolScanMonitor.cs:148`). The added tests flood only at Info and Medium, never at Critical, which is the one severity the attacker controls, which is why the fix reads green. +- **Fix direction:** Do not let attacker-attributable events compete on the same severity axis as host detections. Partition MCP-sourced `CommandAlertEvent`s into a reserved sub-quota that can only evict its own partition, or add a provenance tier ahead of severity (host-detected > agent-self-reported), or clamp MCP-minted pre-flight alerts to Medium and keep true severity only in the returned verdict + durable log. Add a floor so an arriving unacknowledged High/Critical is never its own eviction victim. + +#### HIGH. Genuine Criticals that predate a flood are still evictable (C3) +- **Where:** Equal-severity tie-break is oldest-first (`BoundedEventHistory.cs:32`, `ForemanState.cs:122`); `ForemanEvent.Id` is a fresh GUID per event (`ForemanEvent.cs:22`) so identical flood text does not collapse. A genuine Critical that fired earlier has an older timestamp than every flood item, so once the sub-Critical tiers are exhausted it is the first Critical evicted. The original "a flood evicts genuine Critical alerts" claim still holds for any Critical older than the flood; only the rate changed. +- **Fix direction:** A small dedicated ring for MCP-sourced alerts (e.g. 64 slots) bounds this to a constant regardless of flood duration; never let an agent-minted Critical evict a host-minted Critical of any age. + +#### HIGH. Dashboard `Take(50)` still scrolls a genuine Critical off screen (C3) +- **Where:** `DashboardWindow.xaml.cs:245-248` sorts by a binary pin key `(!Acknowledged && Severity >= High ? 0 : 1)` then descending timestamp. Flood Criticals land in the same bucket 0 and sort newest-first, so 50 of them (~4.2 min) displace every genuine item from the 50-card overview. The pin is a sort key, not a reserved section. A second, wholly unthrottled route: `McpToolScanMonitor.PublishNew` (`:146-150`) emits one High notice per new (server|tool|signal) triple with no rate limit over same-user-writable config files. +- **Fix direction:** Reserve capacity (e.g. 15 oldest-unresolved High/Critical in a fixed strip + 35 by recency), plus a visible "N more not shown" affordance. Also add `.ThenByDescending(e => e.Severity)` so a Critical strictly outranks a High inside the pinned group. + +#### HIGH. `PinnedHeadPublicKeyB64` is outside the seal projection, yet the anchor-forgery alarm's innocence gate depends on the seal covering it (C1) +- **Where:** `SettingsSeal.SecurityProjection` includes only `hashChain = s.LogIntegrity.HashChainEnabled` (`SettingsSeal.cs:52`); `PinnedHeadPublicKeyB64`, `SealHeadEnabled`, `HeadKeyName` (`LogIntegritySettings.cs:18-28`) are absent. But `App.xaml.cs:1078` computes `keyChangeExplainsBadSeals = headSealNotice is not null && LastSealVerdict != Tampered`, on the explicit (commented) assumption that rewriting the pin trips the tamper seal. It does not, because the pin is not in the projection. So the verdict stays `Sealed`, the guard is true, and the Critical/High anchor-**forgery** publish at `:1080-1089` is suppressed. `HeadSealFactory.Build` then verifies anchors against the attacker-supplied pinned bytes (`HeadSeal.cs:102-104`), so counterfeit anchors verify while genuine ones fail. `SealHeadEnabled=false` reaches `NullHeadSigner` (`HeadSeal.cs:77-78`) by the same route. +- **Fix direction:** Add `PinnedHeadPublicKeyB64`, `SealHeadEnabled`, `HeadKeyName` to the projection (a pin is a trust anchor, not a preference), or stop using `LastSealVerdict` as the innocence gate at `:1078`. + +#### HIGH. Decoy read-auditing silently disabled by editing unsealed `PlantedPaths` / `InstanceSentinel` (C1) +- **Where:** The projection seals `decoyEnabled`/`decoyReadAudit` (`SettingsSeal.cs:59-60`) but not `PlantedPaths` or `InstanceSentinel`. `App.xaml.cs:815-818` derives the SACL audit set from `PlantedPaths`; emptying it yields an empty audit set while `Enabled:true, EnableReadAuditing:true` still holds, so the sidecar is `Configure()`d to audit nothing (`:820`) and still restarts/connects under `RunElevated` (`:821`), keeping the supervisor satisfied. Clearing `InstanceSentinel` nulls `CommandAnalyzer.DecoySentinelToken` (`App.xaml.cs:201`) and skips the dynamic cred-040 Critical synthesis (`CommandAnalyzer.cs:59-62`). `DisableReadAuditing` is a presence-gated weakening action (`PresenceLock.cs:79`); this file edit achieves it with verdict `Sealed` and no tap. +- **Fix direction:** Hash the ordered normalized planted-path list into the projection and seal the sentinel, or have the sidecar report "read-auditing enabled but zero paths armed" as a High notice. + +#### HIGH. Settings seal is HMAC-keyed by the same-user-readable `mcp.token`, so a forged seal reads as `Sealed` (C1, default install) +- **Where:** The local seal secret is `new McpAuthToken().Value` (`App.xaml.cs:161-162`), i.e. the contents of `%LocalAppData%\Foreman\mcp.token`, which is deliberately readable by the current user. `SettingsSeal.Compute` is plain HMAC-SHA256 over a source-visible projection. A sophisticated same-user agent reads `mcp.token`, edits `settings.json`, and rewrites `settings.json.seal` + `.lastgood(.seal)` with valid MACs. `Load()` returns `Sealed`, never reverts, no alarm. This bypass is closed only in the opt-in guardian config (secret behind SYSTEM); the default install (`GuardianSettingsSealer.TryCreate` returns null when the guardian is not installed) is exposed. The `SettingsSeal.cs` doc comment still claims detection holds against this actor via "the external OS-event-log anchor and a SACL write-audit on settings.json", but **neither exists**: the only SACL in the codebase is on decoy files (`DecoyAudit.cs:163`), and the log-chain anchor witnesses the event-log head, not `settings.json`. +- **Fix direction:** Key the seal from the machine/guardian boundary by default (guardian-backed sealing on, or DPAPI-machine/TPM), or correct the overstated doc comment and actually apply a write-audit SACL to `settings.json` in the elevated sidecar. + +#### HIGH. Guardian-backed sealing silently degrades to `Unsealed` when the pipe is unreachable at startup, then permanently demotes to the local scheme (C1) +- **Where:** `GuardianSettingsSealer.TryCreate` (`GuardianSettingsSealer.cs:32-47`) returns null if the 2s pipe probe fails, leaving `SettingsStore.Sealer` null (`App.xaml.cs:165`). `Load` then routes a stored `g1:` seal through `SettingsSeal.Verify`, which short-circuits `g1:` to `Unsealed` (`SettingsSeal.cs:126`) with no MAC check, so a directly-edited `settings.json` is adopted (`:93`) with no notice (the `Unverified` Medium at `App.xaml.cs:1050` requires `TryCreate` to have succeeded). Reachable benignly: Foreman auto-starts from HKCU Run at logon while the guardian service is still starting. The next `Save` then writes a local seal over the guardian one (`SettingsStore.cs:120-125`), dropping the install from SYSTEM-boundary to agent-forgeable sealing until the next healthy startup re-binds. +- **Fix direction:** When `GuardianDiscovery.IsGuardianInstalled()` is true but `TryCreate` returns null, do not fall back silently: surface an `Unverified`-class notice and refuse to re-seal a `g1:` seal with a local seal without an explicit operator action. Give the pipe server multiple instances plus a read deadline. + +#### HIGH. `client-policy.json` is written outside the install rollback, so even a FAILED attacker install permanently replaces the trust pin (C2) +- **Where:** `GuardianInstaller.cs:77` calls `policy.Save(ProgramDataDir)` inside the try, before the payload move and `CreateService`. The catch (`:90-126`) rolls back the payload, service, and Program Files dir, but never restores the previous `client-policy.json`. `GuardianService.OnStart` reloads the policy on every start (`GuardianService.cs:28`), and the rollback path itself restarts the service (`:123-124`), so an install that fails at `CreateService`/`StartService` leaves the previously-installed legitimate SYSTEM guardian running with the attacker's pin loaded. +- **Fix direction:** Back up the existing policy before overwriting and restore it in the catch, or defer `policy.Save` until after `CreateService`/`StartService` succeed. Treat the policy file as part of the same atomic install transaction as the payload. + +#### HIGH. A planted DLL is laundered into the trusted sidecar baseline by the restart Foreman recommends (C4) +- **Where:** `SidecarPayloadPin.TryAcquire` (`ElevatedSidecarController.cs:287-307`) enumerates `\sidecar\` and pins every file with `FileShare.Read`, computing no hash and checking no signer. `ValidateSnapshot` (`:309-321`) only asks whether today's file set equals the startup set. Sequence: (1) same-user attacker drops a DLL into `sidecar\` (install dir is `{localappdata}`, `PrivilegesRequired=lowest`); (2) next launch, `SetEquals` fails, launch refused, the High notice at `:228-231` tells the operator to "restart after any development build finishes"; (3) operator restarts; (4) `PinBinaryAtRest` re-enumerates and now pins the attacker's file as legitimate; (5) `SidecarIntegrity.Verify` (`:238`) only inspects the genuine signed EXE, `Process.Start` (`:269`) raises the branded UAC prompt, the elevated process loads the planted DLL. In the shipped release the baseline is a single file, so any second file present at restart is trusted unconditionally. +- **Fix direction:** Ship a signed manifest (file list + SHA-256) generated at publish time; verify every entry before launch and reject any file not in the manifest. Given the single-file release, hardcode the expected payload as exactly `{Foreman.EtwSidecar.exe}` and treat any extra file as fatal. + +#### HIGH. `ValidateSnapshot` runs before the UAC prompt and never again; nothing blocks adding a DLL to the elevated load path (C4) +- **Where:** `ValidateSnapshot` is called at `ElevatedSidecarController.cs:226`; `Process.Start(UseShellExecute=true)` at `:269`, followed by an unbounded wait for the UAC answer and then the full lifetime of the elevated process, none of which re-validates. The pin holds handles on files, so **creating** a new file in `sidecar\` is never prevented. Concrete targets: TraceEvent loads its native helper from `\amd64\KernelTraceControl.dll`, present in the staged Debug payload and absent from the single-file release (free real estate for a plant); any non-KnownDLL system library is app-dir-first under safe DLL search mode. Result: attacker native code at high integrity on the strength of Foreman's branded prompt, the exact CRITICAL 4.4 outcome. (Confidence: likely; depends on winning the TOCTOU race and the load probe firing.) +- **Fix direction:** Harden the ACL on `\sidecar\` to deny `FILE_ADD_FILE`/`FILE_ADD_SUBDIRECTORY` to the interactive user at install time, and launch the sidecar with an image-load mitigation policy (`SetDefaultDllDirectories(LOAD_LIBRARY_SEARCH_SYSTEM32)` in `Program.Main`, plus signature/prefer-system32 process-creation attributes). A re-validation after the UAC return does not close it. + +#### HIGH. CuBroker Held-item exhaustion is fully open (OOM blackout, not addressed) +Found by two red-team passes. +- **Where:** `CuBroker.Prune()` (`CuBroker.cs:741-752`) evicts only `Completed/Failed/Rejected/Blocked`; `Held`/`Auditing`/`Approved`/`Executing` are structurally unprunable, so `MaxItems=200` (`:55`) does not bound them. The rate limiter converts a flood into more Held items and returns at `:171-178` before `Prune()` at `:256` is reached. No general per-caller rate limit exists at the MCP auth gate (`McpServerHost.cs`), and `argsJson` is capped at 64 KiB per action (`ForemanMcpTools.cs:1826`). A harness in the operator's CU driver set, or any authenticated harness in "*"/any mode, calls `cu_submit` in a loop and retains up to 64 KiB per request without bound, OOM-crashing `Foreman.App` and taking the tray, MCP server, and sidecar supervisor with it. Nothing relaunches it. The `RevokeModality` delta does not touch this. +- **Fix direction:** Cap non-terminal items per harness in `SubmitAsync` (reject with a Blocked verdict once the cap is hit), give Held/Auditing a TTL so `Prune` can shed them, publish a High event when the Held queue crosses a threshold. Add Guardian auto-relaunch of `Foreman.App` on crash so an OOM is not an indefinite blackout. + +#### HIGH. Vault master password and decrypted secrets remain plaintext managed strings (not addressed) +- **Where:** `git diff --name-only c5fd504..89633d1` shows zero `src/Foreman.Vault/*` entries. `VaultService.cs:57/77` still take the master password as a managed `string`; `:155/163/209/215/249` hold generated/released secrets as `string`. A co-resident same-user process needs only Task Manager "Create dump file" / `MiniDumpWriteDump` to string-scan the master password and every decrypted secret past the AES-256-GCM+Argon2id+DPAPI envelope, defeating the vault's purpose (agents never see plaintext via `{{vault:}}` injection). The `VaultDocument.cs` doc comment acknowledges this as an open limitation with "future hardening" planned. +- **Fix direction:** Hold the master password and decrypted secrets in pinned, zeroed buffers wrapped with `CryptProtectMemory`/`ProtectedMemory`, decrypt on demand for the shortest window. If accepted as out-of-scope for the same-user boundary, state that explicitly in the audit response rather than leaving the doc comment as the only acknowledgement. + +### 3B. Fix introduced this (Regressions) — see Section 5 for the full list + +The two HIGH regressions belong in this ranking: + +#### HIGH (regression). Sidecar supervisor wedges permanently when an elevated launch never connects +- **Where:** `SidecarSupervisor.cs:81-86` returns early and zeroes `_downTicks` whenever `_launchInProgress()` is true, **before** the relaunch/notify logic. `_launchInProgress` is set in `ElevatedSidecarController.Start()` (`:90`) and cleared only on `Stop()` (`:104`), handshake (`:142`), or `RunAsync`'s `finally` (`:165`). `RunAsync` blocks at `await server.WaitForConnectionAsync(ct)` (`:122`) with **no timeout**. If the sidecar launches (UAC accepted, `Process.Start` succeeds) but dies or hangs before writing its nonce (ETW init crash, AV kill post-elevation, self-check failure), `WaitForConnectionAsync` never returns, `finally` never runs, `_launchInProgress` stays true forever, and `Tick`'s early-return suppresses its own recovery. Net: `expectedUp && !connected`, no relaunch, no `_downNotified` High notice, Setup Health silently shows down. Before this commit there was no gate and this exact failure was handled (grace tick → relaunch x2 → "keeps stopping" High). Only escape now is a manual Settings toggle the operator has no signal to perform. +- **Fix direction:** Stamp a launch time and expire `_launchInProgress` after N seconds, or add a connection timeout to `WaitForConnectionAsync`, so a launched-but-never-connecting sidecar re-enters the normal relaunch/notify path. The supervisor must never suppress its own recovery indefinitely. + +#### HIGH (regression). Settings tamper-revert destroys all operator settings on a documented `mcp.token` rotation +- **Where:** The fix made `Tampered` destructive. Without the opt-in guardian (the default), the seal secret **is** the `mcp.token` value (`App.xaml.cs:161-162`). Deleting `mcp.token` is documented/supported ("Delete mcp.token to force a new token", `McpAuthToken.cs:263`). After rotation, `Verify` uses the new secret against the old-secret seal → mismatch → `Tampered`. `TryReadRecovery` reads `.lastgood`/`.lastgood.seal`, also old-secret sealed → also `Tampered` → returns null. `Load` then `QuarantineTampered`-renames `settings.json` + `.seal` to `*.tampered` and returns `new ForemanSettings()` (defaults). A later `Save` re-seals the defaults, persisting the loss. Every sealed field reverts: presence lock, decoy auditing, ADB enrollment/binary, CU desktop/driver-host, harness trust, mutes, OS event log, Game Mode. Reverting to defaults can **weaken** posture (Game Mode defaults on, presence-lock config dropped), the opposite of fail-closed. Before `89633d1`, `Load` returned settings intact (verdict advisory). +- **Fix direction:** Do not treat a seal-secret mismatch as tampering when the install secret was just rotated. `McpAuthToken.RecentlyRegenerated()` already exists; on `Tampered`, if the secret was just rotated or the recovery snapshot exists but only fails the seal, adopt-and-re-seal instead of quarantine+revert. At minimum require operator confirmation before replacing `settings.json` with defaults, and key the recovery snapshot with a rotation-stable secret. + +--- + +## 4. Medium and Low (condensed) + +**Medium, still open or newly introduced:** +- **C1:** Escalation thresholds (`AlertLevelMediumCount`…`EmergencyLevelTotalAlerts`, `ForemanSettings.cs:156-168`), blanket `NotifyOn*` kill-switches (`:29-32`), `CustomHarnessExes` (`:151`), `PairedExtensionOrigins` (`:106`), `DeadMansSwitch.Enabled` (`:307`), and `PresenceLock.ApprovalTtlSeconds` are all outside the projection; editing them weakens posture with verdict `Sealed`. Invert the policy: project the whole object and explicitly exclude a named cosmetic set (`RequireUserVerification` at `PresenceLock.cs:61-64` already shows the exclusion pattern). +- **C2:** Install silently downgrades an existing publisher-signed pin to path+hash with no confirmation or anti-rollback check (`GuardianClientPolicy.cs:42-55`, `GuardianInstaller.cs:77`). The new regression test asserts on `GuardianInstallReference.LayoutMatches`, a helper production never calls (`GuardianIntegrityTests.cs:29-37`); the real attack shape passes it. `VerifyForInstall`'s gate parameter is a hardcoded literal (`GuardianInstaller.cs:47`), so its false branch is unreachable dead code. +- **C3:** Rate-limit key is attacker-chosen (`caller.HarnessId`) and its map never evicts, so distinct valid identities multiply buckets and grow `_accepted` unbounded (`SuspiciousCommandAlertLimiter.cs:16-17`) — the exact "attacker-inflatable memory" `ForemanState.cs:114-116` caps elsewhere. Throttled drops are invisible, and `:395` now couples the durable `PermissionViolationEvent` to `alertPublished`, so a caller can burn its 12-permit budget on junk and have blocked-command violations go unrecorded. Alert rate-limit was applied to only `report_suspicious_command`; `report_task_start` publishes an Info event with **no** `CanMutate` gate and before any auth branch (`ForemanMcpTools.cs:487`), giving a stolen token an unthrottled event-bus churn primitive. +- **C4:** Any same-user process can permanently disable the elevated tripwire with one file (breaks `SetEquals`) or one deny-ACL subdirectory (makes `TryAcquire` throw → null → all launches refused); the follow-up message misattributes it to a declined UAC prompt. Only 1 of 3 staged helper dirs got the pin: `DesktopCuController.PinBinaryAtRest` and `PilotChannelController.PinBinaryAtRest` still pin the EXE alone, and the Guardian has no pin at all. +- **H-decoy:** 5-min lease TTL orphans the machine-wide audit policy "on" forever after a crash+reboot (`DecoyAuditOwnershipLease.cs:20`, `DecoyAudit.cs:293`); `Start()` failures are invisible (return value discarded at `Program.cs:61`, health is pipe-connectivity only); decoy SACL still audits `ReadData` only so deletion is silent; decoy-paths handoff is still an unvalidated `%TEMP%` file read across the UAC window yielding an elevated arbitrary-path SACL primitive (`ElevatedSidecarController.cs:258-259`, `Program.cs:56-61`). +- **H-misc / regressions:** LiveWeave `TimedOut` unprunable (see Section 6); release purity check misses hidden files (no `-Force`) and covers only `sidecar\`; sidecar payload pin acquired once, so a transient file lock at startup bricks decoy/net-capture for the session. + +**Low (representative):** `--foreman` still builds a policy from an arbitrary path in the console host (`Program.cs:40`, not persisted, low impact); the durable `EventLogStore` still trims by pure recency; eviction went O(1) → O(n log n) under a global lock on the publisher's thread; the new integrity gate has zero automated coverage; `cu_complete_action` and `Claim()` are still not Android-scoped (mislabeling only, executor re-checks enrollment); `cu_status` still leaks the exact `adb.exe` path to any authenticated caller (info leak only, the RCE chain it fed is broken); operator approval copy still says only desktop actions need a tap; the fix breaks the documented lost-authenticator recovery procedure; unconditional lease refresh lets two elevated instances ping-pong ownership. + +--- + +## 5. Regressions (the highest-value section of a round-2 audit) + +The fix pass introduced at least **9** behavior changes that make things worse than `c5fd504`. Two are HIGH (detailed in 3B). The rest: + +1. **HIGH — Sidecar supervisor permanent wedge** (`SidecarSupervisor.cs:81-86`). Silent monitoring blackout; see 3B. +2. **HIGH — Settings destroyed on `mcp.token` rotation** (`SettingsStore.cs:74-91`). Data loss + posture weakening on a documented operation; see 3B. +3. **HIGH — `ProgramData\Foreman\ElevatedState` squat bricks the decoy tripwire.** The rollback+throw path the fix added (`DecoyAudit.cs:197-202`) is new. A non-elevated same-user process pre-creates `%ProgramData%\Foreman\ElevatedState` as a **file** (the parent dir inherits `BUILTIN\Users:Write`; `GuardianInstaller.cs:76` hardens only the `guardian` child). Next elevated run: `HardenMarkerDirectory`'s `Directory.CreateDirectory` throws → `TryWriteAuditPolMarker` returns false → the new rollback disables the policy and throws → `Start()`'s catch runs `Cleanup()` and `StartWatcher()` never executes. Every SACL is stripped, repeats every launch, nothing detects or repairs it. At `c5fd504` these paths swallowed exceptions and the watcher started regardless. +4. **HIGH — auditpol now throws on any non-zero exit** (`DecoyAudit.cs:219-225, 252-253`). `EnableFileSystemAuditingIfNeeded` lost its try/catch, so a transient hiccup, or the guaranteed localized-subcategory failure on non-English Windows (`/subcategory:"File System"` returns exit 87), kills the whole tripwire. Pre-fix it degraded to "policy not ours, watcher still running", which worked on GPO-managed machines. The English `"Success"` substring parse (`:221`) is also unchanged. Address the subcategory by GUID (`{0CCE921D-...}`) and parse the CSV form. +5. **MEDIUM — LiveWeave `TimedOut` is unprunable** (`LiveWeaveBroker.cs:296-306`). `ExpireStale` now converts a stale `Delivered` command to `TimedOut` with `CompletedAt=null`; `Prune` sheds only `Completed`/`Failed`, so `MaxCommands=100` no longer bounds `_commands`. A crashed/hung extension that polls-to-deliver then stops completing leaks unbounded. At `c5fd504` the same command became `Failed` and was prunable. Add `TimedOut` to `Prune`'s victim predicate. +6. **MEDIUM — Sidecar payload pin transient-lock brick** (`ElevatedSidecarController.cs:287-307`, called once at `App.xaml.cs:594`). One AV/indexer/backup sharing race at the wrong instant leaves `_activePayloadPin` null for the session and hard-refuses every launch. Re-attempt with bounded backoff on each `ApplySidecarState`/relaunch. +7. **MEDIUM — LiveWeave deadline gate is a start-mutex, not an execution-mutex** (`service-worker-state.mjs:16-45`). The 45s timeout resets `active=false` without cancelling the in-flight task; a second poll starts and both interleave read-modify-write on `chrome.storage.local` (`liveweaveCanvas`/`History`/`Redo`). The pre-fix `polling=true` held for the whole loop and made this impossible; the "serialized by the poll mutex" comment at `background.js:636` is now false. Thread an `AbortController` into the poll, or gate command execution behind a lock the timed-out task still honors. +8. **LOW — throwing relaunch retries forever** (`SidecarSupervisor.cs:109-110`). Increment moved after `_relaunch()`; if `_relaunch` throws, the budget is never spent and the supervisor retries every 30s silently. Increment before invoking. +9. **LOW — unanswered UAC prompt suppresses the "helper isn't running" notice** (`SidecarSupervisor.cs:84-88`). An operator who walks away from an unanswered prompt gets no High notice that decoy read-auditing / net capture is off, a signal the pre-fix code surfaced. Bound the suppression. + +That the recovery and health-signalling paths are where the regressions cluster is the clearest evidence that the pass was reviewed for "does the reported attack stop" rather than "does the system still behave correctly under failure." + +--- + +## 6. LiveWeave (first coverage) + +The LiveWeave subsystem (MV3 Chrome extension + server-side `LiveWeaveBroker`) was touched by `89633d1` and had not been audited before. The intended change is defensible: a stale `Delivered` command now becomes `TimedOut` with copy telling the agent not to auto-resubmit (`LiveWeaveBroker.cs:94-114`), which removes a genuine double-apply hazard (the old code reported "Failed" for an edit that may already have applied to the canvas). Re-delivery is correctly impossible (`Poll` requires `Pending`, `:172`), late `Complete()` still works (`:205`), and the tool surfaces `terminal`/`outcomeUncertain` (`ForemanMcpTools.cs:1371-1372`). + +But the subsystem carries four issues, two of them regressions from this commit: + +- **MEDIUM (regression) — `TimedOut` unprunable memory leak.** See Section 5, item 5. This is the primary LiveWeave finding. +- **MEDIUM (regression) — deadline gate storage race.** See Section 5, item 7. Concurrent poll loops interleave `saveCanvas` read-modify-write and can silently lose history/redo state. +- **LOW (functional) — `fetchWithTimeout` only bounds the header phase.** `mcp-client.js:9-17` clears the `AbortController` timer in `finally` the moment `fetch()` resolves (headers received); `readJsonRpc` → `res.text()` (`:92-95`) then runs with abort disarmed, so a server that stalls the streamed body hangs the poll indefinitely, which is precisely the >45s overrun that feeds the deadline-gate race. Keep the controller armed until the body is fully read. +- **LOW (security) — export/copy emits agent-authored HTML with no sandbox.** The preview is CSP-locked (`liveweave.html:58` iframe `sandbox="allow-scripts"` + nonce CSP), but `exportDocument` (`project-model.mjs:218-222`) and `copyHtml`/`downloadHtml` (`liveweave.js:233-249`) write `apply_page` markup verbatim with no CSP and no script stripping.

Fast when it’s routine.
Deliberate when it matters.

Attribute

+

Connect the action to a harness, process tree and task episode.

Read context

Combine the command, target, trust level, behaviour and presence state.

Allow routine work, ask the operator, or refuse a bounded broker action.

Record the outcome so later review starts with evidence, not guesswork.

An honest boundary: TraceBrake is safety visibility and a control point for mediated actions—not a Windows sandbox. A process already running as your user may retain the same underlying access as you.
