|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. A remote code execution vulnerability has been reported in Microsoft Active Directory. The vulnerability is due to incorrect freeing of memory by the LDAP service when processing malformed LDAP and LDAPS requests. A remote attacker may trigger this vulnerability by sending a specially crafted LDAP or LDAPS packet to the Active Directory server. Successful exploitation of this vulnerability may allow execution of arbitrary code on a target system.|
This protection will detect and block malformed LDAP requests sent to the vulnerable server.
