HTTP: Dangerous ClassID in ActiveX Object Type 36


This signature detects Web pages containing dangerous ActiveX CLSID references. Malicious Web sites can exploit a known vulnerability in Internet Explorer and gain control of client browsers.

Extended Description

Microsoft Internet Explorer is prone to a buffer-overflow vulnerability that is exposed when certain COM objects are instantiated as ActiveX controls. A malicious webpage could pass content to these objects to trigger memory corruption. Successful exploits could let remote attackers execute arbitrary code in the context of the currently logged-in user.
