 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:
