CVE-2004-1155: Internet Explorer 5.01 through 6 allows remote attackers to spoof arbitrary web sites by injecting content...

Security readout for executives and security teams

This is an old Internet Explorer browser flaw that could let a malicious site place deceptive content into a window associated with a trusted site. The main business risk is phishing, credential theft, or user deception on legacy systems still using affected Internet Explorer versions. Exposure is mainly legacy desktops, kiosks, embedded workflows, or internal applications that still depend on Internet Explorer 5.01 through 6, or IE7 on Windows XP SP2. Modern browsers are not identified as affected in the provided bundle. Treat this as a legacy-risk cleanup item unless affected Internet Explorer systems still access the internet or handle credentials. If they do, prioritize containment or retirement because spoofing trusted sites can directly support phishing and fraud. Mitigation focus: Inventory endpoints and applications still using affected Internet Explorer versions.; Retire or upgrade affected browsers and unsupported Windows environments where feasible.; Restrict legacy browsers from accessing untrusted external websites..
