This script is Copyright (C) 2011-2013 Tenable Network Security, Inc.


Synopsis :

The remote Windows host has an ASP.NET control that could allow
information disclosure.

Description :

An information disclosure vulnerability exists in the version of
Microsoft Chart Control installed on the remote Windows host due to
improper handling of special characters in the URI included in an HTTP
GET request.

If a web application hosted on the affected system uses Microsoft Chart
Control, an unauthenticated, remote attacker could leverage this
vulnerability to read the contents of files located in or under the web
site directory. This may result in the disclosure of sensitive
information that could be used in secondary attacks, especially in the
case of the application's web.config.
