Title: Microsoft Windows Active Directory LDAP Request Handling Remote Code Execution Vulnerability
Severity: CRITICAL
Description:
Lightweight Directory Access Protocol (LDAP) is a protocol that allows authorized users to view or update data in a meta directory. LDAP is used to access data in the Microsoft Windows Active Directory, which is used to provide central authentication and authorization services.
Active Directory is prone to a remote code-execution vulnerability that arises because the application fails to handle specially crafted LDAP or LDAP over SSL (LDAPS) requests and fails to allocate memory in a proper manner.
Successfully exploiting this issue would allow an attacker to execute arbitrary code and gain complete access to a vulnerable computer. The attacker may also be able to cause the affected system to stop responding to further requests and restart.
This issue affects only Windows 2000 servers configured as Active Directory domain controllers.
Affected Products:
- Microsoft Windows 2000 Advanced Server SP4
- Microsoft Windows 2000 Datacenter Server SP4
- Microsoft Windows 2000 Professional SP4
- Microsoft Windows 2000 Server SP4
- Nortel Networks Self-Service CCXML
- Nortel Networks Self-Service VoiceXML
- Nortel Networks Self-Service WVADS
