"The remote Windows host has a version of the McAfee Virtual Technician
/ ePolicy Orchestrator ActiveX control that allows execution of
arbitrary code.  The 'GetObject()' method can be used to load any class
on the underlying operating system.  For example, by loading the
'WScript.Shell' class, attackers can then run arbitrary operating system
commands.

If an attacker can trick a user on the affected host into viewing a
specially crafted HTML document, he can leverage this issue to execute
arbitrary commands on the affected system subject to the user's
privileges."
