Internet Explorer 4.x and 5.x does not properly verify all contents of an SSL certificate if a connection is made to the server via an image or a frame, aka one of two different "SSL Certificate Validation" vulnerabilities.

Security readout for executives and security teams

Old versions of Internet Explorer (4.x and 5.x) failed to fully check SSL certificates when a webpage loaded content through an image or frame. That meant a user could visit what looked like a trusted secure site while embedded content was actually served from a server with a bad or mismatched certificate, undermining the trust signals users relied on. This is a legacy issue in unsupported software. Exposure is effectively negligible today. Internet Explorer 4.x and 5.x are decades out of support and are not present on modern managed endpoints. Any residual risk is limited to isolated legacy systems still running these browsers on unpatched Windows builds. Very low priority. This is a legacy browser flaw from 2000 in software that should not be present in a modern estate. Treat as a hygiene check during legacy-system reviews rather than a standalone remediation project, and prioritize retiring any still-running instances. Mitigation focus: Apply Microsoft bulletin MS00-039 on any legacy Windows systems still running IE 4.x or 5.x.; Retire Internet Explorer 4.x/5.x and move users to a currently supported browser.; Isolate any unavoidable legacy IE hosts from the internet and sensitive internal apps..
