• → Detect exploit attempts by monitoring HTML/script content for instantiation of the four malicious CLSIDs via the 'classid' attribute of an <object> element (e.g., 'clsid:{3BC4F3A3-652A-11D1-B4D4-00C04FC2DB8D}', 'clsid:{4682C82A-B2FF-11D0-95A8-00A0C92B77A9}', 'clsid:{8E71888A-423F-11D2-876E-00A0C9082467}', 'clsid:{606EF130-9852-11D3-97C6-0060084856D4}', 'clsid:{F849164D-9863-11D3-97C6-0060084856D4}'). ↗
• → The vulnerability is triggered through Internet Explorer instantiating COM objects not intended to be used as ActiveX controls; monitor for unexpected in-process loading of ciodm.dll, myinfo.dll, msdxm.ocx, or creator.dll within iexplore.exe. ↗
• → This CVE may be related to BID 17453; correlate detections against the broader set of COM object instantiation abuse patterns in Internet Explorer. ↗

• · The affected COM objects are specific to Windows 2000; the attack surface does not apply to later Windows versions where these objects are absent or differently registered. ↗
• · Arbitrary code execution via this vulnerability has not been confirmed; the primary confirmed impact is memory corruption / denial of service. ↗
