Microsoft Streaming Service Elevation of Privilege Vulnerability

A vulnerability in Microsoft Streaming Service allows an attacker with local access to run code with higher privileges than their account normally permits. This is dangerous because it lets someone bypass security restrictions and gain control over sensitive system functions.

CWE-822 (Improper Synchronization) in Microsoft Streaming Service permits local privilege escalation through a race condition or synchronization flaw. An authenticated local attacker can exploit this to execute arbitrary code in a privileged context, requiring local access but no user interaction beyond initial compromise.
