The Web Proxy Auto-Discovery (WPAD) feature in Microsoft Internet Explorer 6 and 7, when a primary DNS suffix with three or more components is configured, resolves an unqualified wpad hostname in a second-level domain outside this configured DNS domain, which allows remote WPAD servers to conduct man-in-the-middle (MITM) attacks.

Security readout for executives and security teams

CVE-2007-5355 is a WPAD behavior issue in Microsoft Internet Explorer 6 and 7. Under certain DNS suffix configurations, a browser may look for a proxy discovery host outside the intended internal domain, allowing an attacker-controlled WPAD server to intercept web traffic. Exposure is most plausible in legacy environments still using Internet Explorer 6 or 7, WPAD, and multi-component primary DNS suffixes. Modern environments without IE 6/7 are unlikely to be exposed based on the provided sources. Prioritize this where legacy IE 6/7 systems remain in business networks. For modern desktop fleets, urgency is lower, but any surviving legacy browser estate creates preventable traffic interception risk. Mitigation focus: Review Microsoft Security Advisory 945713 and KB 945713 for official guidance.; Inventory remaining Internet Explorer 6 and 7 usage.; Identify systems using WPAD or automatic proxy discovery..
