AhnLab V3 2008.12.4.1 and possibly 2008.9.13.0, 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 an old AhnLab V3 antivirus detection bypass when users browse with Internet Explorer 6 or 7. A malicious HTML file could be made to look different enough that the product failed to detect malware. The issue matters mainly where very old antivirus and browser combinations still exist. Exposure is likely limited to legacy endpoints running the named AhnLab V3 builds with Internet Explorer 6 or 7. The provided sources do not identify modern affected versions, supported platforms, or current deployment prevalence. Prioritize if the organization still has legacy browsing environments, industrial workstations, or unmanaged endpoints. For modern fleets without these old AhnLab and Internet Explorer versions, business urgency is low, but legacy pockets should be removed or isolated. Mitigation focus: Check AhnLab guidance for historical fixes or replacement recommendations.; Remove or isolate systems using Internet Explorer 6 or 7.; Upgrade unsupported AhnLab V3 builds to supported security software..
