Tom Sawyer Software GET Extension Factory COM Object Instantiation Memory Corruption

This script is Copyright (C) 2011-2016 Tenable Network Security, Inc.


Synopsis :

The remote Windows host has a COM object that is affected by a memory
corruption vulnerability.

Description :

Tom Sawyer Software's GET Extension Factory, a component used for
graph visualization applications, is installed on the remote Windows
host. It may have been bundled with a third-party application, such
as the VMware Infrastructure Client or Embarcadero ER / Studio XE2.

The installed version of this component has a vulnerability in that it
does not initialize COM objects properly inside Internet Explorer,
which leads to a memory corruption vulnerability.

If an attacker can trick a user on the affected host into visiting a
specially crafted web page, this issue could be leveraged to execute
arbitrary code on the host subject to the user's privileges.
