Description
phpMyFAQ before 4.1.7 contains a two-factor authentication bypass vulnerability where remember-me tokens are issued before 2FA verification completes. Attackers with valid credentials can obtain a remember-me cookie, skip the 2FA challenge, and replay the cookie to gain full authenticated access without second-factor verification.

AI Analysis

Impact

phpMyFAQ versions prior to 4.1.7 issue remember‑me cookies before the two‑factor authentication (2FA) challenge has finished. An attacker who already has valid user credentials can capture the cookie, skip the second‑factor prompt, and replay it to gain full authenticated access without completing 2FA. The vulnerability allows abuse of the authentication mechanism, effectively lifting the protection provided by 2FA.

Affected Systems

The flaw affects the phpMyFAQ application published by the developer thorsten for all releases before version 4.1.7.

Risk and Exploitability

The CVSS score of 8.6 classifies the flaw as high severity; the EPSS score indicates less than 1%, suggesting a very low exploitation probability. It is not listed in the CISA KEV catalog. Attackers would need legitimate user credentials and the ability to observe or capture the remember‑me cookie, typically through in‑network packet capture or by exploiting a compromised client. Once a cookie is obtained, no additional authentication is required, allowing unrestricted access to the system.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade phpMyFAQ to version 4.1.7 or later to apply the vendor fix.
  • If an upgrade cannot be performed immediately, disable the remember‑me feature in the application configuration so that no cookie is issued until after 2FA.
  • Ensure that all user accounts have 2FA enabled and verify that the remember‑me token is not generated until the second‑factor challenge is completed.
