Microsoft SQL Server <Windows 2000 SP4 - Privilege Escalation
Microsoft SQL Server before Windows 2000 SP4 allows local users to gain privileges as the SQL Server user by calling the xp_fileexist extended stored procedure with a named pipe as an argument instead of a normal file.
The Service Control Manager (SCM) in Windows 2000 creates predictable named pipes, which allows a local user with console access to gain administrator privileges, aka the "Service Control Manager Named Pipe Impersonation" vulnerability.
