The host is installed with Microsoft Windows Server 2003, Server 2008, Server 2008 R2, Windows Vista, Windows 7, Server 2012, Server 2012 R2, Windows 8 or Windows 8.1 and is prone to a security feature bypass vulnerability. A flaw is present in the group policy application of security configuration policies that could cause group policy settings on a targeted system to revert to their default, and potentially less secure, state. Successful exploitation could allow attackers to modify domain controller responses to client requests.
