Vulnerability Title
phpMyFAQ 3.1.0 through 4.1.6 Authentication Bypass via LDAP
Source: CVE Program / CVE List V5
Vulnerability Description
phpMyFAQ versions 3.1.0 through 4.1.6 contain an authentication bypass vulnerability in AuthLdap::create(). When LDAP authentication is enabled, after a successful LDAP bind the code calls User::setStatus('active') unconditionally, which overwrites the account_status column of a pre-existing local account from 'blocked' to 'active'. As a result, a user whose local phpMyFAQ account has been administratively blocked can restore their account and log in by authenticating via LDAP. The state transition is not logged, so administrators cannot detect that the block was overridden. Fixed in 4.1.7.
