ASUS Routers flag Parameter XSS

This script is Copyright (C) 2014-2016 Tenable Network Security, Inc.

Synopsis :

The remote web server hosts a web page that is affected by a cross-
site scripting vulnerability.

Description :

The remote web server fails to sanitize user-supplied input to the
'flag' parameter of the 'error_page.htm' script before using it to
generate dynamic HTML output.

An attacker may be able to leverage this issue to inject arbitrary
HTML or script code into a user's browser to be executed within the
security context of the affected site.

Note that this install is likely affected by an information disclosure
vulnerability, although Nessus has not checked for that.
