FLEXnet Connect Update Service Agent ActiveX (isusweb.dll) Overflow

critical Nessus Plugin ID 24712

Synopsis

The remote Windows host has an ActiveX control that is affected by a buffer overflow vulnerability.

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 FLEXnet Connect on the remote host includes an ActiveX control -- Update Service Agent -- that is reportedly affected by a buffer overflow vulnerability involving its 'Download()' method. 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.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Either upgrade to a version of the FLEXnet Connect SDK with installer version 12.0.0.49974 or later; or, disable the control as described in the US-CERT advisory referenced above.
