Description
phpMyFAQ before 4.1.7 contains a brute-force vulnerability in the two-factor authentication step where the failure counter is session-scoped and reset on each successful password re-authentication. Attackers with a valid password can bypass the five-attempt limit by obtaining a fresh session cookie and repeatedly re-authenticating to reset the counter, enabling unbounded TOTP code guessing.
