This script is Copyright (C) 2015-2017 Tenable Network Security, Inc.

Synopsis :

The remote host has multiple ActiveX controls installed that are
affected by remote code execution vulnerabilities.

Description :

The version of Advantech WebAccess running on the remote host is prior
to 7.0-2011.08.27. Therefore, it includes the ActiveX controls
webdobj.dll and bwscript.dll. These ActiveX controls contain buffer
overflow conditions due to improper validation of user-supplied input.
A remote attacker, using a specially crafted web page, can exploit
these to cause a buffer overflow, potentially resulting in the
execution of arbitrary code.
