🛡️ Sentinel: Fix shell injection risks in entrypoint #27
Conversation
Summary of changes: - Secure `adduser` logic in `entrypoint.sh` by quoting variables and using `read -r` to prevent word splitting and backslash interpretation on passwords. - Fix `VPNCMD_SERVER` and `VPNCMD_HUB` processing loops to correctly iterate over all commands and prevent globbing using `set -f`. - Create `.jules/sentinel.md` to document the security learning. This addresses potential security risks where passwords with spaces or special characters could be truncated or trigger unintended file matching, and ensures all configuration commands are executed safely.

🛡️ Sentinel: Fix shell injection risks in entrypoint
🚨 Severity: HIGH
💡 Vulnerability: Unquoted variable expansion in shell script allowing word splitting and globbing on user input (passwords, commands).
🎯 Impact: Passwords with spaces could be truncated; passwords with glob characters could expand to filenames; multiple VPNCMD commands were not executing correctly.
🔧 Fix: Added quoting,
read -r, andset -f(noglob) where appropriate.✅ Verification: Verified with
tests/test_entrypoint_logic.shensuring correct parsing of complex inputs.PR created automatically by Jules for task 14045139465675695708 started by @bluPhy
