CVE-2019-17201 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. FastTrack Admin By Request 6.1.0.0 supports group policies that are supposed to allow only a select range of users to elevate to Administrator privilege at will. When a user requests elevation using the AdminByRequest.exe interface, the interface communicates with the underlying service (Audckq32.exe) using a .NET named pipe. EPSS estimates a 0.31% chance of exploitation in the next 30 days.

Description

FastTrack Admin By Request 6.1.0.0 supports group policies that are supposed to allow only a select range of users to elevate to Administrator privilege at will. When a user requests elevation using the AdminByRequest.exe interface, the interface communicates with the underlying service (Audckq32.exe) using a .NET named pipe. If the underlying service responds that a user is permitted access to the elevation feature, the client then reinitiates communication with the underlying service and requests elevation. This elevation request has no local checks in the service, and depends on client-side validation in the AdminByRequest.exe interface, i.e., it is a vulnerable exposed functionality in the service. By communicating directly with the underlying service, any user can request elevation and obtain Administrator privilege regardless of group policies or permissions.
