Buffer overflow in the ism.dll ISAPI extension that implements HTR scripting in Internet Information Server (IIS) 4.0 and 5.0 allows attackers to cause a denial of service or execute arbitrary code via HTR requests with long variable names.

Security readout for executives and security teams

This is an old Microsoft IIS flaw in the HTR scripting component. A specially formed HTR request with an overly long variable name can crash the service or potentially run attacker-controlled code. It matters mainly where legacy IIS 4.0 or 5.0 servers remain reachable. Exposure is likely limited to legacy IIS 4.0 or 5.0 installations with HTR scripting through ism.dll reachable. Modern environments are mainly at risk through forgotten servers, legacy applications, lab systems, or embedded/vendor-managed products still running these IIS versions. Treat this as a legacy exposure cleanup issue with high impact if present. The urgent action is to find any reachable IIS 4.0 or 5.0 systems and confirm Microsoft MS02-018 remediation or isolation. Mitigation focus: Review Microsoft MS02-018 and apply the vendor-specified update or workaround.; Inventory externally reachable IIS 4.0 and 5.0 systems.; Confirm whether HTR scripting and ism.dll are enabled or exposed..
