The w3svc.dll ISAPI filter in Front Page Server Extensions and ASP.NET for Internet Information Server (IIS) 4.0, 5.0, and 5.1 does not properly handle the error condition when a long URL is provided, which allows remote attackers to cause a denial of service (crash) when the URL parser accesses a null pointer.

Security readout for executives and security teams

This is a remote denial-of-service flaw in old Microsoft IIS deployments. A specially long URL can make the IIS W3SVC ISAPI handling crash, disrupting web service availability. The provided sources describe service crash risk, not data theft or code execution. Exposure is most plausible where legacy IIS 4.0, 5.0, or 5.1 systems are still reachable and using the affected FrontPage Server Extensions or ASP.NET ISAPI handling. Modern platforms are not identified in the provided CVE bundle. Treat this as a legacy exposure cleanup and availability risk. It should be prioritized for any still-running old IIS web service, especially internet-facing systems, but the provided evidence does not support emergency active-exploitation language. Mitigation focus: Apply Microsoft guidance from MS02-018 where applicable.; Identify and retire or isolate legacy IIS 4.0, 5.0, and 5.1 systems.; Remove unneeded FrontPage Server Extensions or ASP.NET ISAPI exposure on legacy hosts..
