Summary
The LDAP over SSL (aka LDAPS) implementation in Active Directory, Active Directory Application Mode (ADAM), and Active Directory Lightweight Directory Service (AD LDS) in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 does not examine Certificate Revocation Lists (CRLs), which allows remote authenticated users to bypass intended certificate restrictions and access Active Directory resources by leveraging a revoked X.509 certificate for a domain account, aka "LDAPS Authentication Bypass Vulnerability."
Exploit prediction
10.96% chance of exploitation in the next 30 days, higher than 95% of all scored CVEs (FIRST EPSS, 2026-11-09).
