Descriptions

The Windows Kernel API in Windows 8.1 and RT 8.1, Windows Server 2012 and R2, Windows 10 Gold, 1511, 1607, 1703 and 1709, Windows Server 2016 and Windows Server, version 1709 allows an elevation of privilege vulnerability due to the way the Kernel API enforces permissions, aka "Windows Elevation of Privilege Vulnerability". This CVE ID is unique from CVE-2018-0752.

On Microsoft Windows, the check for an AC token when impersonating the anonymous token does not check impersonation token's security level leading to impersonating a non-AC anonymous token leading to privilege escalation.
