high Nessus Plugin ID 56739
Language:
Synopsis
The installed version of Active Directory is affected by a vulnerability that could allow elevation of privileges.Description
The remote Windows host has a version of Active Directory that fails to validate the revocation status of an SSL certificate against the CRL (Certificate Revocation List) associated with the domain account.When Active Directory is configured to use LDAP over SSL, a remote attacker can exploit this and use a previously revoked certificate to authenticate to the Active Directory domain as the user associated with that certificate. This would give him access to the network resources or ability to run code on the affected host, subject to the privileges of that user.
Solution
Microsoft has released a set of patches for Windows XP, 2003, Vista, 2008, 7, and 2008 R2.See Also
