Description
phpMyFAQ before 4.1.7 contains a two-factor authentication bypass vulnerability where remember-me tokens are issued before 2FA verification completes.

Executive Summary

This vulnerability is a two-factor authentication (2FA) bypass in phpMyFAQ versions before 4.1.7. Attackers with valid credentials can obtain a remember-me cookie before completing 2FA verification. They can then replay this cookie to gain full authenticated access without completing the second-factor check.

Detection Guidance

Check phpMyFAQ logs for successful logins without 2FA completion. Look for sessions where remember-me cookies were issued immediately after password verification. Inspect network traffic for cookie replay attempts or sessions authenticated solely via remember-me tokens.

Impact Analysis

An attacker could gain full access to your phpMyFAQ account without completing 2FA. This could lead to unauthorized data access, privilege escalation, or complete account takeover. The remember-me cookie allows persistent access even after session expiration.

Compliance Impact

This vulnerability defeats MFA protection, which is a key requirement for compliance with standards like GDPR and HIPAA. It could lead to unauthorized data exposure, violating data protection regulations and potentially resulting in legal penalties or compliance failures.

Mitigation Strategies

Upgrade phpMyFAQ to version 4.1.7 or later immediately. Disable the remember-me feature if 2FA is enabled. Review all active sessions and invalidate any remember-me tokens issued before 2FA completion.
