Title: Microsoft Windows 2000 Domain Controller DoS Vulnerability
Severity: MODERATE
Description:
Domain controllers in a Windows 2000 network handle user authentication and various other required tasks.
Microsoft Windows 2000 domain controllers are subject to a denial of service condition.
Unfortunately Windows 2000 domain controllers do not properly validate a user request before attempting to process it. Submitting numerous specially crafted invalid requests to a domain controller, could initiate the domain controllers attempt to carry out the request. This constant processing attempt will eventually exhaust nearly all available system resources, preventing the domain controller from handling various mandatory tasks.
A restart of the server is required in order to gain normal functionality.
Successful exploitation of this vulnerability could assist in further attacks against the victim host.
