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).
