The window.showHelp() method in Internet Explorer 5.x does not restrict HTML help files (.chm) to be executed from the local host, which allows remote attackers to execute arbitrary commands via Microsoft Networking.

Security readout for executives and security teams

This old Internet Explorer 5.x issue allowed a webpage to invoke HTML Help files from a remote location instead of only local files, potentially leading to arbitrary command execution through Microsoft Networking. Modern exposure should be uncommon, but any retained legacy IE 5.x environment deserves attention. Likely limited to legacy systems still running Internet Explorer 5.x or applications that embed that engine and allow access to remote .chm content over Microsoft Networking. Prioritize remediation only where legacy IE 5.x exists. For normal modern estates, urgency is low; for unsupported legacy systems, the business risk is high because the stated impact is arbitrary command execution. Mitigation focus: Identify and retire Internet Explorer 5.x usage wherever possible.; Check Microsoft or vendor legacy guidance for the applicable historical fix.; Block untrusted remote .chm access where legacy systems remain..
