Author: Larry W. Cashdollar, @_larry0

Description: 
Huge-IT Product Catalog is made for demonstration, sale, advertisements for your products. Imagine a stand with a 
variety of catalogs with a specific product category. To imagine is not difficult, to use is even easier.

Vulnerability:
The following code does not prevent an unauthenticated user from injecting SQL into functions via 'load_more_elements_into_catalog' located in ajax_url.php. 

Vulnerable Code in : ajax_url.php

 11 define('_JEXEC', 1);
 12 defined('_JEXEC') or die('Restircted access');
.

.
308         } elseif ($_POST["post"] == "load_more_elements_into_catalog") {
309             $catalog_id = $_POST["catalog_id"];
310             $old_count = $_POST["old_count"];
311             $count_into_page = $_POST["count_into_page"];
312             $show_thumbs = $_POST["show_thumbs"];
313             $show_description = $_POST["show_description"];
314             $show_linkbutton = $_POST["show_linkbutton"];
315             $parmalink = $_POST["parmalink"];
316             $level = $_POST['level'];
.
.
.
359             $query->select('*');
360             $query->from('#__huge_it_catalog_products');
361             $query->where('catalog_id =' . $catalog_id);
362             $query->order('ordering asc');
363             $db->setQuery($query, $from, $count_into_page);
