Summary

AVideo LoginControl contains an authentication bypass vulnerability in the PGP second factor verification that compares challenge responses using loose equality against an uninitialized session variable. Attackers with a victim's password can bypass the second factor by sending a parameter-less GET request to verifyChallenge.json.php, which evaluates null == null and marks authentication complete.

Risk Assessment

An attacker with knowledge of a victim's password can completely bypass the second authentication factor and gain account access. This undermines trust in the 2FA mechanism in AVideo LoginControl.

Recommendation

Apply available patches or workarounds for AVideo LoginControl, and if none are available, consider disabling PGP second factor verification until fixed. Enforce strong, unique passwords and monitor for unusual logins.
