FreeBSD : pligg -- XSS and Cross-Site Request Forgery (bec38383-e6cb-11de-bdd4-000c2930e89b)

This script is Copyright (C) 2009-2014 Tenable Network Security, Inc.

Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

secunia reports :

Russ McRee has discovered some vulnerabilities in Pligg, which can be
exploited by malicious people to conduct cross-site scripting and
request forgery attacks.

Input passed via the 'Referer' HTTP header to various scripts (e.g.
admin/admin_config.php, admin/admin_modules.php, delete.php,
editlink.php, submit.php, submit_groups.php,
user_add_remove_links.php, and user_settings.php) is not properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

The application allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
requests. This can be exploited to e.g. create an arbitrary user with
administrative privileges if a logged-in administrative user visits a
malicious website.
