🔒 Enforce SSL verification across all proxy links - #9
Conversation
This commit addresses a security vulnerability where SSL certificate verification could be disabled, exposing users to Man-in-the-Middle (MITM) attacks. - Modified `DomainFronter` to enforce `verify_ssl=True` and log a security warning if it was set to `False`. - Removed all manual overrides that set `ssl.CERT_NONE` and `check_hostname = False` in `domain_fronter.py`, `proxy_server.py`, and `h2_transport.py`. - Ensured consistent use of `ssl.create_default_context()` for all outbound TLS connections. - Added ALPN advertisement for `http/1.1` in the proxy's SNI-rewrite tunnel to maintain compatibility.

🔒 Security Fix: Enforce SSL Verification
🎯 What:
The vulnerability allowed users (or a malicious configuration) to disable SSL certificate verification and hostname checking. This insecure state made the proxy susceptible to MITM attacks, which could lead to the theft of sensitive data such as the
Auth Key.If left unfixed, an attacker positioned between the proxy and the relay (e.g., on the local network or ISP level) could intercept and potentially modify the traffic, compromising the user's connection and credentials.
🛡️ Solution:
I have strictly enforced SSL verification project-wide by:
DomainFronterto override any insecureverify_ssl=Falseconfiguration with a warning.domain_fronter.py,proxy_server.py, andh2_transport.pythat explicitly disabled SSL security measures.Verification was performed using a local mock server with a self-signed certificate, confirming that the proxy now correctly rejects untrusted connections even when configured to bypass verification.
