Name of the Vulnerable Software and Affected Versions Microsoft Windows Server 2003 SP2 Microsoft Windows Vista SP2 Microsoft Windows Server 2008 SP2 and R2 SP1 Microsoft Windows 7 SP1 Microsoft Windows 8 Microsoft Windows 8.1 Microsoft Windows Server 2012 Gold and R2 Microsoft Windows RT Gold and 8.1

Description The issue allows local users to gain privileges by conducting a junction attack to load another user's UsrClass.dat registry hive. An elevation of privilege vulnerability exists in how the Windows User Profile Service (ProfSvc) validates user privilege, allowing an authenticated attacker to potentially execute programs with elevated permissions by loading registry hives associated with other user accounts.

Recommendations For Microsoft Windows Server 2003 SP2, update to a newer version to mitigate the risk. For Microsoft Windows Vista SP2, update to a newer version to mitigate the risk. For Microsoft Windows Server 2008 SP2 and R2 SP1, update to a newer version to mitigate the risk. For Microsoft Windows 7 SP1, update to a newer version to mitigate the risk. For Microsoft Windows 8, update to a newer version to mitigate the risk. For Microsoft Windows 8.1, update to a newer version to mitigate the risk. For Microsoft Windows Server 2012 Gold and R2, update to a newer version to mitigate the risk. For Microsoft Windows RT Gold and 8.1, update to a newer version to mitigate the risk. As a temporary workaround, consider restricting access to the Windows User Profile Service (ProfSvc) to minimize the risk of exploitation.
