CVE-2006-0057: Microsoft Internet Explorer 5.01, 5.5, and 6 allows remote attackers to bypass the Kill bit settings for da...

Security readout for executives and security teams

This is an old Internet Explorer issue where crafted HTML could bypass the browser’s Kill bit protection for dangerous ActiveX controls. That protection was meant to stop unsafe controls from loading, so bypassing it could reopen attack paths administrators believed were blocked. Exposure is most likely limited to legacy Windows environments that still permit Internet Explorer 5.01, 5.5, or 6 to render untrusted HTML, including intranet apps, kiosks, or old virtual machines. Treat this as a legacy-risk cleanup item with high impact if old Internet Explorer remains in use. It is not a modern internet-wide emergency unless those obsolete browsers still support business processes. Mitigation focus: Inventory systems that still run Internet Explorer 5.01, 5.5, or 6.; Remove legacy Internet Explorer from untrusted browsing workflows.; Check Microsoft and CERT guidance for MS05-054 applicability..
