CVE-2002-1186: Internet Explorer 5.01 through 6.0 does not properly perform security checks on certain encoded characters...

Security readout for executives and security teams

This old Internet Explorer flaw could let a malicious site redirect a user in a way that exposes sensitive information from another site. It affects Internet Explorer 5.01 through 6.0 per the CVE description. The business risk mainly exists where very old browser versions remain in use. Exposure is most plausible on legacy endpoints or compatibility environments still using Internet Explorer 5.01 through 6.0. The source bundle does not identify affected operating systems, newer browsers, or server-side products. Treat this as a legacy-risk cleanup item, not a current enterprise-wide emergency unless old Internet Explorer remains in business workflows. Prioritize discovery and removal of unsupported browsers. Mitigation focus: Identify and retire Internet Explorer 5.01 through 6.0 usage.; Apply Microsoft guidance from security bulletin MS02-066 where still relevant.; Restrict legacy browser access to untrusted internet content..
