…ers grant install_sudoers_dropin could report success after an install(1) that never wrote anything, and step_systemd_services used that success as permission to remove /etc/sudoers.d/90-clawbox-nopasswd. On a device whose only grant was the blanket one, the sequence ended with NEITHER file: no working sudo at all, on an appliance with no console. Two independent defects made that possible. Both call sites ran the function as the tested command of a condition (`if install_sudoers_dropin …`, `… || echo`). Bash suspends `set -e` for the whole dynamic extent of such a command, so every unchecked line inside the function body was silently non-fatal too — the staging `cat`, the backup `cat`, the `install` into /etc/sudoers.d and the rollback `install` (whose "rolled back" message printed either way). And the function's own success signal could not see the failure: the closing `visudo -c` re-reads whatever is on disk, so after a failed install it happily validated the OLD file and returned 0. Now every step inside the function carries its own check, the destination is verified BYTE-FOR-BYTE against the staged candidate (an ENOSPC-truncated file still parses under visudo, so only a comparison can catch it), the caller invokes it plainly and reads an explicit status, and the quarantine is gated on a second, load-bearing proof: `cmp -s` between the shipped allow-list and what is actually in /etc/sudoers.d/clawbox. A fact about the device, not about a code path. Tests extract the real gate out of install.sh rather than re-implementing it, and simulate a refusing install(1), a silently truncated install(1) and a failing `visudo -c` — asserting in each case that the blanket drop-in survives.

… result
The EXEMPT_CALLS rationale for `sudo -n hermes gateway restart --system` says
the call is install-time-only and non-fatal. It is neither.
ensureHermesGateway takes `sudo: systemScope` on the RESTART branch too, and
that branch is what every Telegram, WhatsApp, Discord and Email config save
hits on a provisioned Hermes box. It execs /home/clawbox/.local/bin/hermes,
which the clawbox user owns and can rewrite, so it could never be allow-listed
— which is exactly why it had to be exempted, and why the restart silently
stopped working once the blanket grant was gone.
It was silent because runHermesCli RESOLVES on a non-zero exit, and the status
check that follows runs `hermes gateway status` WITHOUT sudo: it sees the old
process still serving, answers running: true, and /setup-api/telegram/configure
replies {restarted: true} for a restart that never happened. The owner's new
bot token then quietly kept not working.
`hermes gateway install --system` writes a root-owned unit that runs
User=clawbox (verified against the CLI's unit template), so a systemctl restart
of it is a ZERO-ESCALATION grant — strictly less than the existing `restart
clawbox-gateway`, whose unit has no User= at all. The system-scope branch now
takes that path with `-n`; the user-scope branch stays on the CLI, because
`systemctl --user` from a system service would target root's session bus, and
its exit code is checked instead of assumed.
ensureHermesGateway now returns an `applied` flag saying whether the change it
attempted actually took, and every caller requires it alongside `running`
before claiming a restart. `stopHermesEmailPolling` gains a "restart-failed"
outcome so the email route warns instead of reporting that receiving stopped.
`gateway install --system` stays deliberately ungranted: it writes into
/etc/systemd/system and cannot be expressed safely against a clawbox-writable
binary. It fails fast under `sudo -n`, and `applied` now carries that outward.

The exemption claimed the only caller was install-time-only and non-fatal. That covered two different calls: the first-time `gateway install --system`, where it is true, and the RESTART branch, where it was not — every Telegram, WhatsApp, Discord and Email config save on a provisioned box goes through it. The restart now runs through the granted systemctl path, so the exemption describes exactly one call again, and says how its failure is surfaced. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The `restart hermes-gateway` grant trips the guard in
install-foreign-edition-teardown.test.ts, exactly as that guard was written to
do. Revisiting it rather than deleting it, because the blanket rule it encoded
("no Hermes unit may appear in sudoers at all") is stricter than its own reason.
The two directions of the teardown defend different things. clawbox-gateway is
foreign on hermes because it is an unauthenticated agent surface on :18789 — a
security boundary, so the teardown removes the unit file AND masks it, which
kills the grants there. hermes-gateway is foreign on openclaw because two
harnesses polling one Telegram token deadlock each other — a functional
conflict, and the teardown deliberately only stops and disables it. It cannot
mask it: that unit is written by the UPSTREAM Hermes installer, so a persistent
mask would make a later `hermes gateway install --system` write to /dev/null,
which is the exact trap step_edition_gateway_state's unmask branch exists to
undo.
So the grant is allowed, and the tripwire keeps its teeth: hermes-dashboard (a
web surface) stays completely ungranted, and hermes-gateway gets `restart` and
nothing else — the assertion is now an anchored exact match on both spellings,
so `start`, `enable`, `stop` or `unmask` would each fail it. The teardown must
also still bring the unit down, so the grant only ever restarts a gateway that
belongs on the device.
Flagging this in the PR: it relaxes a guard someone else wrote on purpose, and
it should be confirmed rather than assumed.

…ASK-445) The granted chain is `sudo systemctl start clawbox-root-update@<step>.service` -> the root-owned dispatcher -> `/home/clawbox/clawbox/install.sh --step <step>`. Only the middle link was root-owned. install.sh is clawbox:clawbox 0755 inside a clawbox-writable directory -- install.sh hands the tree back with `chown -R clawbox:clawbox` on every root run -- and the steps it dispatches go on to run more of that same tree as root (scripts/start-ap.sh, launch-browser.sh, setup-hermes-edition.sh, ...). So the grant also meant "clawbox may choose the program root runs", which is passwordless local root in two moves for anything with clawbox-level code execution: the web server, the in-UI terminal, the agent's shell. The tree cannot be moved out of clawbox's reach -- the updater has to replace it and the app has to build in it -- so root now refuses to run code it did not record. config/clawbox-root-manifest.sh writes and verifies a root-owned sha256 manifest of install.sh, scripts/ and config/ under /etc/clawbox; the dispatcher verifies it before the exec, for every step including the update family. An update legitimately replaces those files, but it does so from inside install.sh after the gate and re-records them as it goes: install.sh's bootstrap block and sync_repo_to_update_target both rewrite the manifest immediately after a successful `git reset --hard`. Ordering matters more than the check. install_root_libexec writes the manifest FIRST and installs the dispatcher only if that succeeded, because a dispatcher newer than its manifest refuses every root step -- no password change, no hostname change, no hotspot restart, on an appliance with no console. If the record cannot be written the previous dispatcher stays where it is and the run records a provision failure, exactly as install_sudoers_dropin keeps the drop-in that is already there. step_chpasswd now validates on the root side too. It read $PROJECT_DIR/data/.chpasswd-input -- clawbox-writable -- and piped it straight into chpasswd, with every guard on the record living in src/lib/chpasswd.ts on the unprivileged side. Dropping `root:<new>` in there and starting the granted unit set ROOT's password. The step now requires exactly one record, naming exactly $CLAWBOX_USER, with a non-empty password and no CR, refuses a symlinked input, and scrubs the file whether it accepted it or not. Recorded residual: clawbox is in the `sudo` group, so setting the clawbox account's own password is still a route from clawbox code execution to an interactive root shell; that is the owner's administrator account and removing it would lock the only administrator out of a console-less box. Also records the accepted residual in sudoers_grants_blanket_nopasswd -- a blanket line in /etc/sudoers itself, a User_Alias, or an over-broad-but-not-ALL rule are knowingly out of scope, with the behavioural `sudo -n` probes in e2e-install as the compensating control.
… prefix (TASK-445) `reset-failed clawbox-*`, `start --no-block clawbox-*` and `start clawbox-root-update@*.service` read like a scope and were not one. sudoers(5) matches a command's arguments as ONE concatenated string, so `*` spans whitespace, and `systemctl start` takes a LIST of units. Reproduced against sudo 1.9.9 -- the Ubuntu 22.04 vintage the appliance ships -- with `sudo -U clawbox -l <cmd>`, which tests matching without executing: start --no-block clawbox-setup.service ssh.service ALLOWED start clawbox-root-update@chpasswd.service ssh.service ALLOWED reset-failed clawbox-a ssh.service ALLOWED i.e. "start any unit as root, passwordless" with one clawbox- word in front. Regex Cmnd arguments would say this directly but arrived in sudo 1.9.10, after the version on the device, so the rules are enumerated instead: one exact (verb, unit) pair per command the product issues. Only four `clawbox-root-update@` instances are reachable from the web server -- chpasswd, set_hostname, restart_ap and llamacpp_install -- so the update family (bootstrap_updater, git_pull, build, rebuild, post_update, update_smoke) is no longer startable through sudo at all. All six probes above now deny, and the eleven commands the product really issues still match. check-sudoers-coverage.sh gains the two shape invariants, so this cannot drift back without failing CI: no Cmnd_Spec may contain `*` or `?` anywhere, and every granted command must resolve under a root-owned prefix (/bin, /sbin, /usr/bin, /usr/sbin, /usr/local/libexec/clawbox). The second one fails a grant on /home/clawbox/clawbox/install.sh or /home/clawbox/.local/bin/hermes by construction, which is the GAP 2 shape written as a build rule. Grant matching is exact comparison now that wildcards are rejected at parse time. e2e-install/06-sudoers.spec.ts asserts the same things on a device install.sh provisioned: `sudo -n -l` must DENY an appended unit name and must still ALLOW the real commands; no granted path may be owned or group/world-writable by anyone but root; the root-exec manifest must exist 644 root:root and verify; a planted extra file under scripts/ must make the dispatcher refuse; and a planted `root:` chpasswd record must leave root's hash untouched. The container now seeds BOTH blanket drop-in names a device is seen with. The factory-baked `90-clawbox-nopasswd` is not written by anything in this repo -- it arrives in the flashed image -- so quarantine_overbroad_sudoers is the only thing that can clear it, and the fixture has to look like a real device.
`execFile("/usr/bin/systemctl", ["start", "ollama"])` had no sudo and used the
bare unit name. It works today only because of the unscoped polkit
`manage-units` grant -- the one thing that still makes the whole allow-list
bypassable, tracked separately as TASK-539. The moment that grant goes, this
call fails with "Interactive authentication required" and factory reset stops
deleting Ollama models, silently.
The sudoers rule is `start ollama.service`, and sudoers matches arguments
exactly, so the bare `ollama` spelling would not have matched it either. Both
halves fixed here so the polkit removal is a straight deletion rather than a
deletion plus a silent feature regression.

… root (TASK-445)
Same defect class as the chpasswd record, and it had three live members. Root
reads several files out of $PROJECT_DIR/data, which the web server writes as the
clawbox user, and it read them with `source` -- i.e. arbitrary ROOT code
execution for anything that can already run code as clawbox: the web server, the
in-UI terminal, the agent's shell.
* install.sh::read_configured_hostname did `. data/hostname.env`, and
clawbox-root-update@set_hostname.service is one of the four instances the
allow-list grants. `printf 'id > /tmp/pwn\n' > data/hostname.env` plus the
granted unit was root in one move.
* install.sh sourced data/network.env at the TOP LEVEL, so it ran on every
root invocation of the script, `--step chpasswd` included. A root-owned copy
at /etc/clawbox/network.env already existed and is what the unit loads.
* scripts/start-ap.sh sourced data/hotspot.env. clawbox-ap.service and
clawbox-ap-watchdog.service carry no User=, so it runs as root, and
clawbox-root-update@restart_ap.service is granted.
All of them now read a single KEY=VALUE assignment out of the file, strip one
layer of quotes, and refuse a symlinked input. install.sh additionally rejects a
value containing anything but [A-Za-z0-9._-] -- both of its keys are an
interface name and a hostname, and the caller still validates the meaning.
start-ap.sh does not filter the character set, because a WiFi PSK may
legitimately contain almost anything; the values there only ever become argv
elements for nmcli, never shell.
The rule this leaves is one line long: root parses files under data/, it never
evaluates them. /etc/clawbox/*.env is still sourced, and that is fine -- root
owns those.
…TASK-445)
The first cut of the manifest gate was too strict in three ways, each of which
would have bricked real devices. CI found two of them before this landed
anywhere: the e2e-install container failed the setup wizard, the password
change, the in-app upgrade and the power test, all with the same root cause.
* A file ADDED under a covered path is no longer tampering. Root only ever
executes files install.sh names explicitly and all of those are recorded, so
an unrecorded file is not something root can be made to run -- while failing
on additions turns any stray file under scripts/ into a device that refuses
every root step for good. scripts/__pycache__ alone did it:
gateway-pre-start.sh (the gateway's ExecStartPre) imports
scripts/gateway_origins.py, so CPython writes a .pyc there the first time the
gateway starts, after the manifest was written -- and again under a new name
after any python3 minor-version bump. __pycache__, node_modules and .venv are
pruned from the record for the same reason.
* The gate covers the pinned steps, not the update family. An update is a
legitimate rewrite of exactly the covered files, and it is not always
install.sh doing the rewriting: src/lib/updater.ts runs its own fetch /
reset --hard / clean -fd as the clawbox user before starting the rebuild
step, and scripts/force-update.sh does the same by hand. Verifying there
fails those flows at their next step and leaves the device refusing every
root step afterwards. The update family re-records as its first action
instead, which is also what heals a tree replaced from the outside. This is
not a hole in the allow-list: no sudo grant names a self-updating instance.
* The backslash guard in write_manifest matched a literal `*`, not a
backslash, so a name sha256sum would have to escape could be recorded and
then fail verification for good. Both cases are now tested.
scripts/root-update-step.sh -- the shim for field devices whose deployed unit
still names it -- now delegates to the root-owned dispatcher instead of exec'ing
install.sh directly. It falls through to the legacy path only when
/usr/local/libexec/clawbox does not exist at all (a genuinely pre-migration
device, which needs that one run to install the dispatcher); when the directory
is there but the dispatcher is not, it refuses rather than papering over a
half-installed box with a root exec.
The e2e probes are behavioural now. `sudo -n -l` cannot answer this question on
a real device: install.sh puts clawbox in the `sudo` group and the distro ships
`%sudo ALL=(ALL:ALL) ALL`, so `sudo -l <anything>` says "yes, with a password"
for every command on the box. `sudo -n <cmd>` distinguishes them -- a command
the allow-list covers runs, one it does not gets sudo's own "a password is
required" -- and that is also exactly what the web server sees. Verified on a
throwaway Ubuntu 22.04 with clawbox in the sudo group AND the narrow list
installed: all six deny probes deny, the control still runs. Appended-unit
probes now use a deliberately non-existent unit name, so a regression fails the
test without starting anything real.
Also from the review pass: the factory-reset ollama start goes through
src/lib/local-ai-runtime's startOllamaService() rather than a second hand-rolled
systemctl call (that helper is where the argv is already pinned to the
Cmnd_Spec, it passes -n, and it keeps the unprivileged dev fallback); the three
comments that still described the grant as `clawbox-root-update@*.service` say
what it is now; scripts/pr-review.mjs's sensitive-path list covers the files
that are the root-side gate; and grant_matches is a joined-string compare now
that wildcards are rejected at parse time.

…nd it (TASK-445) /usr/bin/snap is granted for the Browser app's chromium recovery and the e2e container has no snapd, so `stat` exits non-zero and dockerExec throws before a single assertion runs. The check is 'nothing that resolves is clawbox-writable', not 'everything resolves' -- so tolerate the missing ones and keep the must-exist requirement for the libexec helpers, which are ours to install and which the neighbouring test already pins at 755 root:root.

Remove the verify-to-exec race.
"$MANIFEST_HELPER" --verify completes before the later Bash process opens $ENTRYPOINT. A clawbox process can replace /home/clawbox/clawbox/install.sh in that interval. Root then executes the replacement.
Do not execute a path in $PROJECT_DIR after verification. Promote verified code into a root-owned immutable location, then execute that copy.
As per path instructions, config/** requires review for “correct dependencies and security settings.”

systemd systemctl start failed service start-limit-hit reset-failed manual start official documentation
💡 Result:
To resolve a systemd service that has failed with a start-limit-hit error (often accompanied by the message Start request repeated too quickly), you should use the following command: sudo systemctl reset-failed <service_name> The official documentation for systemctl explains that when a service hits its configured start limit (governed by StartLimitIntervalSec= and StartLimitBurst=), it enters a state where it refuses to start again [1][2][3]. Running systemctl reset-failed <service_name> resets the service's failed state, clears its exit code and status, and crucially, resets the start rate limit and restart counters to zero [1][2][4]. Once this command is executed, the service will once again be eligible for starting [1][5]. It is important to note that this command is a recovery tool and does not address the underlying cause of the failures [6][7]. Because the service hit its start limit, it is likely crashing or failing to start due to a configuration error, missing dependency, or invalid environment. Before or after resetting the state, you should: 1. Identify the root cause by checking the service's logs using: journalctl -u <service_name> [7][5]. 2. Inspect the service status to view the specific error: systemctl status <service_name> [7][8]. 3. If you have modified the service unit file to fix the issue, remember to reload the systemd manager configuration before attempting to restart: sudo systemctl daemon-reload [9]. Once the issue is corrected, you can manually start or restart the service normally using: sudo systemctl start <service_name> [5]

Add reset-failed grants for set_hostname and restart_ap. Their callers invoke systemctl start directly. Repeated failures can hit systemd’s start limit because the template does not disable rate limiting. A later start then fails until reset-failed runs.

Use a dedicated staging directory for sudoers candidates.
The repository documents /var/lib/clawbox/clawkeep.cred as owned by clawbox. Setting the existing parent directory to 0700 root:root prevents the clawbox user from traversing it and can make that state inaccessible.

🌐 Web query:
For the sudo version supported by Ubuntu 22.04, does a sudoers Cmnd_Spec containing /usr/bin/../home/clawbox/clawbox/payload match when invoked with that exact pathname, and does sudo canonicalize the pathname before matching?
💡 Result:
In Ubuntu 22.04 (Jammy Jellyfish), the installed sudo version is typically 1.9.9 [1][2][3]. Regarding your query about whether a sudoers Cmnd_Spec containing /usr/bin/../home/clawbox/clawbox/payload matches when invoked with that exact pathname: 1. Matching Behavior: Sudo does not treat pathnames in the sudoers file as glob-like patterns unless they explicitly contain wildcard characters (e.g., *,?). When you provide an exact path in the sudoers file (like /usr/bin/../home/clawbox/clawbox/payload) and invoke sudo with that same exact string, sudo performs a string comparison for the command path. If the strings match exactly, it will generally be permitted, assuming the command is otherwise valid and authorized [4][5][6]. 2. Path Canonicalization: Sudo does not automatically canonicalize (or resolve) path traversal sequences like.. (dot-dot) in the sudoers file itself for the purpose of command matching [6][7]. Sudo is designed to be very strict and literal with pathnames to avoid unintended security consequences. Because it performs string-based matching, the literal path /usr/bin/../home/clawbox/clawbox/payload is treated as a distinct command path. If you enter that exact string on the command line, it matches the sudoers entry [6]. However, if you were to invoke /home/clawbox/clawbox/payload (the canonical version of the path), it would not match the sudoers entry containing the /usr/bin/../.. path traversal string, as they are different strings [6][7]. Security Warning: Relying on paths containing path traversal (..) in a sudoers file is dangerous and explicitly discouraged [8][9]. Because sudo does not canonicalize these paths for matching purposes, a user who is permitted to execute a command with wildcards in the path may be able to use path traversal to execute arbitrary files that you did not intend to authorize [8][9]. Always use absolute, canonical paths in your sudoers configuration to ensure security [8].

Reject . and .. path components before checking approved prefixes.
index($path, $_) == 0 accepts /usr/bin/../home/clawbox/clawbox/payload. Sudoers matches this literal pathname, while filesystem resolution reaches a path outside /usr/bin/. Reject traversal components or canonicalize the path before the prefix check.

Strip trailing CR characters from hotspot.env values.
For CRLF input, read_env_value retains \r after ${line#*=}. The value then reaches nmcli as part of the SSID or PSK, which can prevent clients from connecting. Strip the carriage return before quote handling.

Keep factory-reset cleanup on the local Ollama instance.
getOllamaBaseUrl() accepts any non-empty OLLAMA_HOST value. deleteOllamaModels() lists models and sends DELETE /api/delete for each model at that URL. A remote OLLAMA_HOST can make a local factory reset delete models from a shared Ollama server. Restrict cleanup to the local endpoint or validate ownership before issuing deletes.

CodeRabbit's critical finding on this PR, and it is right: `--verify` returns,
and bash opens $ENTRYPOINT afterwards. The clawbox user can replace install.sh
in that window, and a rewrite loop wins it comfortably -- so the check answered
a question about a file that was no longer the one root executed.
The dispatcher now installs install.sh into /run/clawbox (tmpfs, 0700 root:root,
so clawbox cannot reach it) at 0500 root:root, hashes THAT COPY through a new
`clawbox-root-manifest.sh --verify-file`, and execs the copy. The bytes checked
and the bytes run are the same bytes. The name is fixed rather than mktemp'd
because `exec` replaces this shell and no EXIT trap would fire to clean up.
The residual is recorded in the code rather than implied: the scripts install.sh
goes on to run as root are covered by the tree-wide --verify but are opened
later, by install.sh itself, so the same window exists for them. Closing that one
means the tree install.sh reads from being root-owned too, which is the follow-up
this design points at.
Four more review findings, all valid:
* set_hostname and restart_ap had no `reset-failed`. clawbox-root-update@.service
does not set StartLimitIntervalSec=0, so a step that failed a few times hits
systemd's start limit and every later start is refused until something clears
it -- which on those two paths was nothing. The three callers now reset-failed
first, as the chpasswd and llamacpp hand-offs already did, and the two grants
are added.
* SUDOERS_STAGING_DIR was /var/lib/clawbox itself, staged 0700 root:root. That
directory is shared -- clawbox-power-mode.sh keeps its clock snapshot there
and the first-boot VNC marker lives there -- so the mode change could stop a
non-root reader from even traversing it. Staging moved to a subdirectory.
* sudo compares the command path as a string and never canonicalises it, so
`/usr/bin/../home/clawbox/clawbox/payload` would pass the root-owned prefix
check while naming a file clawbox can write. Any `.` or `..` component in a
granted path is now a build failure.
* The factory reset's ollama cleanup went through getOllamaBaseUrl(), which
honours OLLAMA_HOST -- so a device pointed at a remote Ollama would have
issued /api/delete against somebody else's server. Pinned back to loopback;
what it cleans is this device's own models under /usr/share/ollama.
And a fourth member of the source-as-root class the review did not reach:
scripts/ap-watchdog.sh did `. "$HOTSPOT_ENV"` in a subshell. The subshell

parses now, keeping the property the sourcing was chosen for (a quoted SSID

Closes GAP 2, GAP 2b, GAP 3, MINOR 6 and MINOR 7 from Mike's independent audit of #471 (
445-strict-verify), plus two more members of the GAP 2b class the audit did not reach. MINOR 5 was already fixed by #495 (fc15707d). GAP 1 (the unfiltered polkitmanage-unitsgrant) is deliberately NOT in this PR — it is TASK-539 and lands in its own PR right after this one, so the two can be reviewed and reverted independently.Base is
fix/hermes-sudoers-445-r2(#471's head), stacked on #495.GAP 2 — root no longer runs code the clawbox user can rewrite
The granted chain is
Only the middle link was root-owned. Confirmed again on a box flashed today (2026-08-27, main @
227c26f1):and the steps install.sh dispatches go on to run more of that same tree as root:
scripts/start-ap.sh(recover, restart_ap),scripts/launch-browser.sh,scripts/setup-hermes-edition.sh,scripts/setup-tunnel.sh,scripts/install-voice.sh. So the grant also meant "clawbox may choose the program root runs" — passwordless local root in two moves for anything with clawbox-level code execution: the web server, the in-UI terminal, the agent's shell.The tree cannot be moved out of clawbox's reach — the updater has to replace it and the app has to build in it — so root now refuses to run code it did not record.
config/clawbox-root-manifest.sh(new, root-owned, installed to/usr/local/libexec/clawbox/) writes and verifies a sha256 manifest ofinstall.sh,scripts/andconfig/at/etc/clawbox/root-exec.manifest(0644 root:root, staged inside root-owned/etc/clawbox, never/tmp).config/clawbox-root-step.shverifies it before the exec.install.shre-records it wherever the covered tree legitimately changes: the bootstrap block (right after a successfulgit reset --hard origin/<branch>, before the re-exec) andsync_repo_to_update_target(which bothstep_git_pullandstep_bootstrap_updatergo through).Three design decisions are load-bearing, and each of them is there because the strict version bricks devices:
src/lib/updater.ts:498runs its ownfetch/reset --hard/clean -fdas the clawbox user before starting the rebuild step, andscripts/force-update.shdoes the same by hand. Verifying there fails those flows at their next step and leaves the device refusing every root step afterwards. Instead the update family re-records as its first action, which is also what heals a tree replaced from the outside. This is not a hole the allow-list leaves open: GAP 3 below removes every sudo grant for a self-updating instance.scripts/into a permanent refusal.scripts/__pycache__alone would have done it:gateway-pre-start.sh(the gateway'sExecStartPre) importsscripts/gateway_origins.py, so CPython writes a.pycthere the first time the gateway starts — after the manifest was written, and again under a new name after any python3 minor-version bump.__pycache__/node_modules/.venvare pruned from the record for the same reason.install_root_libexecwrites the record and installs the dispatcher only if that succeeded — a dispatcher newer than its manifest refuses every root step. On failure the previous dispatcher stays where it is and the run records a provision failure, the same ruleinstall_sudoers_dropinfollows for the allow-list.scripts/root-update-step.sh— the shim for field devices whose deployed unit still names it — now delegates to the root-owned dispatcher instead of exec'ing install.sh directly, so a device still on the old unit is inside the fix rather than outside it. It falls through to the legacy path only when/usr/local/libexec/clawboxdoes not exist at all (a genuinely pre-migration device, which needs that one run to install the dispatcher); when the directory exists but the dispatcher does not, it refuses.GAP 2b — and two more of the same class the audit did not reach
step_chpasswdread$PROJECT_DIR/data/.chpasswd-input— clawbox-writable — and piped it straight intochpasswd, with every guard living on the unprivileged side insrc/lib/chpasswd.ts. Droppingroot:<new>in there and starting the granted unit set root's password. The root side now requires exactly one record, naming exactly$CLAWBOX_USER, with a non-empty password and no CR; refuses a symlinked input; and scrubs the file whether it accepted it or not.Reviewing that fix turned up two live siblings, both worse, because they
sourcerather than parse — i.e. arbitrary root code execution, not just a wrong password:install.sh::read_configured_hostnamedid. "$PROJECT_DIR/data/hostname.env"as root. That file is written by the web server, andclawbox-root-update@set_hostname.serviceis one of the four instances the allow-list grants.printf 'id > /tmp/pwn\n' > data/hostname.env+ the granted unit was root, in one move.install.shsourced$PROJECT_DIR/data/network.envat the top level, i.e. on every root run of the script,--step chpasswdincluded. A root-owned copy at/etc/clawbox/network.envalready existed and is what the unit loads.scripts/start-ap.shsourceddata/hotspot.env.clawbox-ap.serviceandclawbox-ap-watchdog.servicecarry noUser=, so it runs as root — andclawbox-root-update@restart_ap.serviceis granted.All three now parse a
KEY=VALUEline instead of evaluating the file, and reject a symlinked input. The rule is one line long: root parses files underdata/, never evaluates them.TASK-445's "no git/network work in password changes" still holds and is now asserted:
chpasswdis not inSELF_UPDATING_STEPS, so the dispatcher pins it withCLAWBOX_INSTALL_BOOTSTRAPPED=1.Recorded residual:
clawboxis in thesudogroup, so setting the clawbox account's own password is still a route from clawbox code execution to an interactive root shell. That is the owner's administrator account; removing it would lock the only administrator out of a console-less box. What this closes is the part that was never intended — changing a different account's password, root's included.GAP 3 — no wildcards, because a prefix was not a scope
reset-failed clawbox-*,start --no-block clawbox-*andstart clawbox-root-update@*.servicelooked scoped and were not. sudoers(5) matches a command's arguments as one concatenated string, so*spans whitespace — andsystemctl starttakes a list of units.Reproduced against sudo 1.9.9, the Ubuntu 22.04 vintage the appliance ships, with
sudo -U clawbox -l <cmd>(tests matching, executes nothing). Same host, same probes, old rules vs this PR:start clawbox-root-update@chpasswd.service ssh.servicestart --no-block clawbox-root-update@llamacpp_install.service ssh.servicereset-failed clawbox-root-update@chpasswd.service ssh.servicestart --no-block clawbox-setup.service ssh.servicereset-failed clawbox-a ssh.servicestart clawbox-root-update@git_pull.servicestart clawbox-root-update@build.servicestart clawbox-root-update@bootstrap_updater.servicestart --no-block clawbox-root-update@post_update.serviceRegex Cmnd arguments would say this directly, but they arrived in sudo 1.9.10 — after the version on the device — so the rules are enumerated: one exact
(verb, unit)pair per command the product issues. Only fourclawbox-root-update@instances are reachable from the web server (chpasswd,set_hostname,restart_ap,llamacpp_install), which is also what makes the update family sudo-unreachable and lets GAP 2's gate exclude it safely.MINOR 6 / MINOR 7
setup/reset/route.tsstarted ollama with a baresystemctl start ollamaand no sudo — it worked only through GAP 1's polkit grant, andollamawould not have matched theollama.servicerule anyway. It now calls the sharedstartOllamaService()fromsrc/lib/local-ai-runtime.ts, which is where the argv is already pinned to the Cmnd_Spec, passes-n, keeps the unprivileged dev fallback, and waits for the API — replacing a hand-rolled retry loop.sudoers_grants_blanket_nopasswdrecords its accepted residual in a comment: a blanket line in/etc/sudoersitself, aUser_Alias, and an over-broad-but-not-ALLrule are knowingly out of scope, with the behaviouralsudo -nprobes ine2e-installas the compensating control.Mechanical enforcement — a regression fails CI

Grant matching is exact comparison now that wildcards are rejected at parse time./bin,/sbin,/usr/bin,/usr/sbinor/usr/local/libexec/clawbox. A grant on/home/clawbox/clawbox/install.shor/home/clawbox/.local/bin/hermesfails by construction — GAP 2's shape written as a build rule. A relative command is rejected too:secure_pathis a convenience, not a privilege boundary.Verified firing (each appended to a fixture allow-list, checker run, exit 1):
New/changed tests:
src/tests/unit/root-exec-manifest.test.ts(new) — drives the real shippedclawbox-root-manifest.shandclawbox-root-step.shwith their constants retargeted at a temp tree: records + verifies; refuses a rewritteninstall.sh, a rewrittenscripts/start-ap.sh, a removed file, a missing manifest; does not refuse an added file or a__pycache__churn; refuses a filename sha256sum would have to escape while accepting one containing*; refuses and never execs; fails closed with no verifier; pinschpasswdwhile letting the update family through. Also coversinstall_root_libexec's manifest-before-dispatcher ordering and the keep-the-old-dispatcher fallback.src/tests/unit/install-chpasswd-validation.test.ts(new) — runs the realstep_chpasswdwith/usr/sbin/chpasswdredirected to a recorder (acceptsclawbox:, keeps colons, refusesroot:, another account, a smuggled second record, a CR, an empty password, a symlinked input — asserting each time that nothing reachedchpasswd), and a second block proving root no longer evaluateshostname.envorhotspot.env.src/tests/unit/sudoers-coverage.test.ts— eight new cases for the two shape invariants.src/tests/unit/root-steps.test.ts— the wildcard tripwire is inverted (no grant may contain*/?, the four reachable instances must be named, no self-updating step may be), plus a case asserting the verification happens before the exec.e2e-install/06-sudoers.spec.ts— on a device install.sh really provisioned. The probes are behavioural (sudo -n <cmd>, classified on sudo's own "a password is required"):sudo -n -lcannot be used here, because install.sh puts clawbox in thesudogroup and%sudo ALL=(ALL:ALL) ALLmakessudo -lanswer "yes, with a password" for everything on the box. Appended-unit probes use a deliberately non-existent unit name so a regression fails the test without starting anything real.Provisioning: the blanket rule ships from the factory
Worth stating plainly, because it changes what "fixed" means. Nothing in this repo writes
clawbox ALL=(ALL) NOPASSWD: ALL. It is created by the flash pipeline, twice — once into the rootfs image before flashing and once over SSH during first-boot setup — so every device is born with it and gets it re-created on every provisioning run.Measured on the box flashed today:
08:33 is the flasher; 09:41 is install.sh. That ordering is why
quarantine_overbroad_sudoers(#471) is the only thing that can clear it from devices already in the field, and why the image itself needs fixing so new devices are born clean — tracked separately.The e2e container is therefore seeded with both blanket names seen on real devices, spelled
NOPASSWD:ALLandNOPASSWD: ALL, and both must end up in quarantine — the detector parses the rule rather than matching text, and the fixture now looks like a real device.What is deliberately still open
GAP 1 — the unfiltered polkit
manage-unitsgrant — remains open, and TASK-445 cannot be marked done while it is.config/49-clawbox-updates.pklagrantsorg.freedesktop.systemd1.manage-unitswith no unit condition (.pklaon polkit 0.105 cannot express one), which issystemd-run— arbitrary root — for the clawbox user, andstep_polkit_rules(install.sh) activelyrm -fs the correctly-scoped.rulestwin. Tracked as TASK-539; the PR follows this one.Three notes from this work that feed straight into it:
clawbox-root-update@<step>.serviceinstances they use, since wildcards are now a build failure. That is the intended cost: each new root entrypoint gets reviewed as a privilege boundary.fetch/reset --hard/clean -fdinsrc/lib/updater.ts:498and let the existinggit_pull/bootstrap_updaterroot steps do it, since they already sync and re-record), not to widen the gate.config/49-clawbox-updates.rules— the scoped twinstep_polkit_rulesdeletes — already documents the bounded set (unit.indexOf("clawbox-root-update@") === 0), which is exactly the list the sudoers migration needs.Two root-executes-clawbox-writable paths found while doing this are not fixed here, because neither is reachable through a sudo grant and both are boot units that need hardware to re-test:
clawbox-ap.service/clawbox-ap-watchdog.service(ExecStartinside/home/clawbox/clawbox/scripts, noUser=) andclawbox-firstboot-vnc.service. Their inputs are fixed above; their entrypoints want the same libexec treatment asclawbox-root-step.shin a follow-up.Summary by CodeRabbit
