Mono ASP.NET action Attribute XSS

This script is Copyright (C) 2009-2012 Tenable Network Security, Inc.


Synopsis :

The remote web server contains a development framework that is
affected by a cross-site scripting vulnerability.

Description :

The remote host is running Mono, an open source, UNIX implementation
of the Microsoft .NET development platform.

The version of Mono installed on the remote host fails to encode
user-supplied input to the URL before using it for the default
'action' of a form. 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.
