Microsoft Windows 2000 NCM handler routine could allow elevated privileges
| win2k-ncm-gain-privileges (9856) |  High Risk |
Description:
Microsoft Windows 2000 could allow a local attacker to gain elevated privileges on the system caused by a vulnerability in the Network Connection Manager (NCM) handler routine. NCM is a component in Windows 2000 that processes user requests for network resources and calls a handler routine whenever a new connection is established. A local attacker could create and install a malicious custom handler routine, which would allow the attacker to gain complete control over the affected system, once a network connection is established that calls this routine.
Platforms Affected:
- Microsoft, Windows 2000
Remedy:
Apply the patch for this vulnerability, as listed in Microsoft Security Bulletin MS02-042. See References.
