NVD Description

Note: Versions mentioned in the description apply only to the upstream lemonldap-ng package and not the lemonldap-ng package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

An issue was discovered in LemonLDAP::NG before 2.16.1. Weak session ID generation in the AuthBasic handler and incorrect failure handling during a password check allow attackers to bypass 2FA verification. Any plugin that tries to deny session creation after the store step does not deny an AuthBasic session.
