CKEditor sample_posteddata.php XSS

This script is Copyright (C) 2013-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The version of the CKEditor installed on the remote host is affected by
a cross-site scripting vulnerability because it fails to properly
sanitize user-supplied input to the 'sample_posteddata.php' script. An
unauthenticated, remote 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 this version is reportedly also affected by a cross-site
request forgery (CSRF) vulnerability as well as a path disclosure issue.
However, Nessus did not test for these additional issues.
