The Client-Server Run-time Subsystem (CSRSS) in Microsoft Windows 8.1, Windows Server 2012 Gold and R2, Windows RT 8.1, and Windows 10 Gold and 1511 mismanages process tokens, which allows local users to gain privileges via a crafted application, aka Windows CSRSS Security Feature Bypass Vulnerability.
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
