DotNetNuke __dnnVariable Parameter XSS

This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

The remote web server contains an ASP.NET application that is
affected by a cross-site scripting vulnerability.

Description :

The version of DotNetNuke installed on the remote host is affected
by a cross-site scripting vulnerability because the application fails
to properly sanitize user-supplied input to the ' __dnnVariable'
parameter. An attacker may be able to leverage this to inject
arbitrary HTML and script code into a user's browser to be executed
within the security context of the affected site.

Note that the application is reportedly also affected by an
additional cross-site scripting issue as well as a redirect
error that can lead to phishing attacks
however, Nessus has not
tested for these additional issues.
