DESCRIPTION:
A security issue has been reported in Microsoft's Web Proxy
Auto-Discovery (WPAD) feature, which can be exploited by malicious
people to conduct man-in-the-middle (MITM) attacks.

The problem is that the WPAD feature resolves "wpad" hostnames up to
the second-level domain, which is potentially untrusted. This can be
exploited to conduct man-in-the-middle attacks against third-level or
deeper domains.

Successful exploitation requires e.g. that the system has a primary
DNS suffix configured (please see the vendor's advisory for details
and other mitigating factors).

SOLUTION:
The vendor has provided various workarounds. Please see the vendor's
advisory for details.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Beau Butler.
