|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.
