No EUVD known-exploited evidence

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.

What, why and how

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.

Why

When a security-critical event occurs, the product either does not record the event or omits important details about the event when logging it.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may bypass an access boundary or take over an account.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Reference recorded

A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.
