A vulnerability has been identified in Microsoft Windows, which could be exploited by malicious users to gain knowledge of sensitive information. This issue is due to a design error where the Web Proxy Autodiscovery Protocol (WPAD) is used (by default) without static WPAD entries, which could be exploited by attackers on a local network segment to force WPAD clients (e.g. Internet Explorer) to route their traffic through a malicious proxy server by registering a specially crafted WPAD entry in Domain Name System (DNS) or in Windows Internet Naming Service (WINS).
