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.
AnalysisAI
Two-factor authentication bypass in phpMyFAQ before 4.1.2 lets unauthenticated remote attackers brute-force any administrator's six-digit TOTP code by submitting sequential POST requests to the /admin/check endpoint, which lacks session binding and rate limiting. CVSS 4.0 scores this 9.3 with no public exploit identified at time of analysis, though a proof-of-concept is described in the GHSA advisory and SSVC marks exploitation as 'poc' with total technical impact. …
