CVE-2022-37186Network attack vector

Session impersonation via incomplete handler invalidation

Published Apr 16, 2023 · Updated Feb 6, 2025

Insufficient session expiration in LemonLDAP::NG before 2.0.15 allows remote attackers to retain access through an invalidated session. The session-deletion path fails to ensure that every handler stops accepting a session after the portal removes its central record. The condition requires at least two servers and manual deletion before automatic expiry, leaving the session usable for impersonation.
