Title: Microsoft Windows 2000 RPC Service Privilege Escalation Vulnerability
Severity: MODERATE
Description:
Microsoft Windows 2000 uses Remote Procedure Calls (RPC) for client-server communications in a distributed computing environment (DCE). TCP Port 135 is typically used for DCE endpoint resolution.
A vulnerability was previously reported which causes a denial of service against the DCE-RPC endpoint mapper (BID 6005). If a system service crashes as a result of this denial of service, there is a possibility that it will orphan a named pipe.
This named pipe could then be hijacked by a malicious user in order to escalate their privilege level on the system when a privileged process attempts to connect to the orphaned pipe. This could result in a complete system level compromise.
