FLEXnet Connect Update Service ActiveX Control Multiple Code Execution Vulnerabilities

This script is Copyright (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

The remote Windows host has an ActiveX control that allows execution
of arbitrary code.

Description :

Macrovision FLEXnet Connect, formerly known as InstallShield Update
Service, is installed on the remote host. It is a software management
solution for internally-developed and third-party applications, and
may have been installed as part of the FLEXnet Connect SDK, other
InstallShield software, or by running FLEXnet Connect-enabled Windows
software.

The version of the FLEXnet Connect client on the remote host includes
an ActiveX control -- the InstallShield Update Service Agent -- that
is marked as 'safe for scripting' and contains several methods that
allow for downloading and launching arbitrary programs. If a remote
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.

Additionally, it is reportedly affected by a buffer overflow that can be
triggered by passing a long argument for 'ProductCode' to the
'DownloadAndExecute()' method.
