CVE-2002-1254: Internet Explorer 5.5 and 6.0 allows remote attackers to bypass the cross-domain security model and access...

Security readout for executives and security teams

This is an old Internet Explorer issue where a malicious web page could break the browser’s same-origin protections. The source description says attackers could access local or cross-domain information and possibly execute code. Business risk is mainly for legacy systems still using IE 5.5 or 6.0. Exposure is likely limited to legacy Windows environments, kiosk systems, old industrial workstations, or preserved virtual machines running IE 5.5 or 6.0. Modern browsers are not identified as affected in the supplied sources. Prioritize this only where legacy Internet Explorer remains in operational use. For those systems, the issue is serious because web content could cross trust boundaries and access data. For modern fleets without IE 5.5 or 6.0, urgency is low. Mitigation focus: Identify and remove Internet Explorer 5.5 and 6.0 from production systems.; Apply or verify Microsoft MS02-066 guidance where legacy hosts cannot be retired.; Restrict legacy browser access to untrusted websites and email-rendered HTML..
