🛡️ Sentinel: [MEDIUM] Fix shell variable expansion and logic errors in entrypoint

Vulnerability:

  1. Unquoted variable expansion in adduser $username $password caused passwords containing spaces to be truncated (e.g., "secure pass" became "secure").
  2. Logic error in VPNCMD_SERVER and VPNCMD_HUB loops caused only the first command in a semicolon-separated list to be executed, potentially skipping security configurations.

Fix:

  • Quoted all variables in adduser call: adduser "$username" "$password".
  • Refactored VPNCMD_* loops to correctly iterate over the array of commands.
  • Quoted $CONFIG variable usage.

Verification:

  • Verified syntax with bash -n.
  • Created and ran a reproduction script (temporary) that confirmed the fix handles passwords with spaces correctly.
  • Logic review confirms the loop fix ensures all configuration commands are executed.
