HTTP: Microsoft Windows Messenger ActiveX Control Code Execution

This signature detects attempts to use unsafe ActiveX controls in Microsoft Windows Messenger. An attacker can create a malicious Web site containing Web pages with dangerous ActiveX controls, which if accessed by a victim, allows the attacker to gain control of the victim's client browser.

Extended Description

Microsoft Windows Messenger ActiveX control ('msgsc.dll') is prone to a remote code-execution vulnerability. An attacker can exploit this issue by enticing an unsuspecting user to view a specially crafted webpage. Successful exploits will allow the attacker to execute arbitrary code within the context of the application (typically Internet Explorer) that uses the ActiveX control.
