CRITICAL:
Less critical
IMPACT:
Privilege escalation
WHERE:
Local system
OPERATING SYSTEM:
Microsoft Windows 2000 Professional
Microsoft Windows 2000 Server
Microsoft Windows 2000 Advanced Server
Microsoft Windows 2000 Datacenter Server
DESCRIPTION:
A vulnerability has been identified in Windows 2000, which can be
exploited by malicious, local users to escalate their privileges on a
vulnerable system.
The vulnerability is caused due to a validation error in the way the
Utility Manager handles Windows messages. This can be exploited by
running a specially crafted program, which sends a special Windows
message to the Utility Manager allowing arbitrary code to be run with
escalated privileges.
Successful exploitation grants Local System privileges to the
malicious user.
SOLUTION:
Apply patch or Service Pack 4.
