Title

Unauthorized accounts must not have the Replace a process level token user right. (Cat II impact)

Discussion

Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities. The "Replace a process level token" user right allows one process or service to start another process or service with a different security access token. A user with this right could use this to impersonate another account.
