Who is Vulnerable?
Vulnerability Description	Active Directory provides central authentication and authorization services for Windows-based systems. Active Directory Application Mode (ADAM) is a Lightweight Directory Access Protocol (LDAP) directory service that runs as a user service. An authenticated elevation of privilege vulnerability has been discovered in implementations of Active Directory on Microsoft Windows. The vulnerability is due to the way that the Local Security Authority Subsystem Service (LSASS) improperly handles certain LDAP messages. A remote attacker may trigger this vulnerability by sending specially crafted LDAP messages to a listening LSASS server. Successful exploitation of this vulnerability could allow the attacker to execute arbitrary code and take complete control of an affected system.
