DESCRIPTION:
Kacper has reported some vulnerabilities in ScozNews, which can be
exploited by malicious people to compromise a vulnerable system.

Input passed to the "CONFIG[main_path]" parameter in several files is
not properly verified before being used to include files. This can be
exploited to execute arbitrary PHP code by including files from local
or external resources.

Affected files:
sources/functions.php
sources/help.php
sources/mail.php
sources/news.php
sources/template.php
sources/Admin/admin_cats.php
sources/Admin/admin_edit.php
sources/Admin/admin_import.php
sources/Admin/admin_templates.php

Successful exploitation requires that "register_globals" is enabled.

The vulnerabilities have been reported in version 1.2.1. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified.
