Windows DNS Server in Microsoft Windows 2000 SP4, Server 2003 SP1 and SP2, and Server 2008, when dynamic updates are enabled, does not restrict registration of the "wpad" hostname, which allows remote authenticated users to hijack the Web Proxy Auto-Discovery (WPAD) feature, and conduct man-in-the-middle attacks by spoofing a proxy server, via a Dynamic Update request for this hostname, aka "DNS Server Vulnerability in WPAD Registration Vulnerability," a related issue to CVE-2007-1692.

The Group Policy Security Configuration policy implementation in Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 allows man-in-the-middle attackers to disable a signing requirement and trigger a revert-to-default action by spoofing domain-controller responses, aka "Group Policy Security Feature Bypass Vulnerability."
