Summary

Duplicate Advisory: phpMyFAQ enables unauthenticated 2FA brute-force attack via /admin/check acceptance of arbitrary user-id

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-9pq7-mfwh-xx2j. This link is maintained to preserve external references.

Original Description

phpMyFAQ before 4.1.2 contains an improper restriction of excessive authentication attempts vulnerability in the /admin/check endpoint, which accepts arbitrary user-id parameters without session binding or rate limiting. Unauthenticated attackers can brute-force any user's six-digit TOTP code by submitting POST requests with sequential token values, bypassing two-factor authentication to gain full administrative access.
