K7AntiVirus 7.10.541 and possibly 7.10.454, when Internet Explorer 6 or 7 is used, allows remote attackers to bypass detection of malware in an HTML document by placing an MZ header (aka "EXE info") at the beginning, and modifying the filename to have (1) no extension, (2) a .txt extension, or (3) a .jpg extension, as demonstrated by a document containing a CVE-2006-5745 exploit.

Security readout for executives and security teams

This CVE describes a legacy antivirus detection bypass affecting K7AntiVirus 7.10.541 and possibly 7.10.454 when used with Internet Explorer 6 or 7. A malicious HTML document could be disguised in ways that evade detection. The main business concern is missed malware prevention on obsolete endpoints, not confirmed compromise. Exposure is most likely limited to legacy Windows endpoints still running the named K7AntiVirus versions with Internet Explorer 6 or 7. Modern browsers, current endpoint security, and retired K7 builds are not identified as affected by the provided sources. Treat this as a legacy risk cleanup item unless affected systems are still in production. If they are, prioritize removal or isolation because the issue weakens a primary malware prevention control on obsolete browsing stacks. Mitigation focus: Identify and retire affected K7AntiVirus versions and Internet Explorer 6 or 7 usage.; Check K7 vendor guidance or support channels for historical fixes or upgrade paths.; Disable legacy Internet Explorer browsing where operationally possible..
