Vulnerability Details : CVE-2015-0002

The AhcVerifyAdminContext function in ahcache.sys in the Application Compatibility component in Microsoft Windows 7 SP1, Windows Server 2008 R2 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 does not verify that an impersonation token is associated with an administrative account, which allows local users to gain privileges by running AppCompatCache.exe with a crafted DLL file, aka MSRC ID 20544 or "Microsoft Application Compatibility Infrastructure Elevation of Privilege Vulnerability."

- Metasploit Modules Related To CVE-2015-0002

MS15-001 Microsoft Windows NtApphelpCacheControl Improper Authorization Check
On Windows, the system call NtApphelpCacheControl (the code is actually in ahcache.sys) allows application compatibility data to be cached for quick reuse when new processes are created. A normal user can query the cache but cannot add new cached entries as the operation is restricted to administrators. This is checked in the function AhcVerifyAdminContext. This function has a vulnerability where it doesn't correctly check the impersonation token of the caller to determine if the user is an administrator. It reads the caller's impersonation token using PsReferenceImpersonationToken and then does a comparison between the user SID in the token to LocalSystem's SID. It doesn't check the impersonation level of the token so it's possible to get an identify token on your thread from a local system process and bypass this check. This module currently only affects Windows 8 and Windows 8.1, and requires access to C:\Windows\System\ComputerDefaults.exe (although this can be improved).
