Microsoft IIS 5.0 allows remote attackers to cause a denial of service via an HTTP request with a content-length value that is larger than the size of the request, which prevents IIS from timing out the connection.

Security readout for executives and security teams

CVE-2001-1186 is an old denial-of-service issue in Microsoft IIS 5.0. A malformed HTTP request can keep server connections from timing out, potentially tying up resources and making a web service unavailable. The supplied sources do not show data theft, code execution, or current active exploitation. Exposure is most likely limited to legacy systems still running Microsoft IIS 5.0, especially internet-facing web servers. The supplied affected-product metadata is incomplete, but the CVE title and description identify IIS 5.0. Treat this as a legacy-technology risk. It is not supported by evidence of current exploitation here, but any internet-facing IIS 5.0 service represents avoidable availability exposure and should be retired or isolated. Mitigation focus: Identify and retire or upgrade any remaining IIS 5.0 deployments.; Check Microsoft or vendor guidance for supported fixes or configuration recommendations.; Reduce internet exposure for any legacy IIS 5.0 services still required..
