Summary

phpMyFAQ before version 4.1.7 fails to persist the WebAuthn login challenge, allowing an attacker who captures a successful WebAuthn assertion to replay it indefinitely and authenticate as the user without interaction or hardware key.

Risk Assessment

An attacker can take over a user's account without knowing the password or possessing the hardware key, leading to unauthorized access to application data and functions.

Recommendation

Upgrade phpMyFAQ to version 4.1.7 or later, which includes a fix preventing the anti-replay comparison from being skipped.

Original NVD description (English source)

phpMyFAQ before 4.1.7 fails to persist the WebAuthn login challenge generated by prepareForLogin, because neither WebAuthn controller saves the mutated key objects back to the database. At login the anti-replay comparison is skipped by its own null guard, allowing an attacker who captures a successful WebAuthn assertion to replay it indefinitely and authenticate as the user without any interaction or hardware key.
