Summary

AVideo through c3edcc274c389816d434acadac07ee78eaf330c1 contains an authentication bypass vulnerability in LoginControl::verifyChallenge() that uses loose comparison (==) instead of strict comparison (===) against unset session values. Attackers with only a password can submit an empty request to verifyChallenge.json.php to bypass PGP two-factor authentication and gain full authenticated access.

Risk Assessment

The risk includes unauthorized access to user accounts, including administrators, despite enabled two-factor authentication, potentially leading to full system compromise.

Recommendation

Immediately patch the code to use strict comparison and update the system when a patch becomes available.
