Overview
phpmyfaq/phpmyfaq is a FAQ system for PHP and MySQL, PostgreSQL and other databases
Affected versions of this package are vulnerable to Improper Authentication via the check endpoint, which allows authentication based solely on a valid 6-digit TOTP token and a user-chosen user-id, without requiring prior password verification. An attacker can gain unauthorized access to any account with two-factor authentication enabled by submitting a valid or brute-forced TOTP code and the corresponding user-id. This is only exploitable if the target account has two-factor authentication enabled and the attacker can determine or guess the user-id.
