[+] Bugs  
  
  
- [A] Local File Inclusion  
  
[-] Risk: hight  
[-] File affected: index.php  
  
This bug allows a guest to include local files.  
The following is the vulnerable code:  
  
...  
  
if (isset($_GET['lang'])) { $_SESSION['lang'] = $_GET['lang'];}  
  
...  
  
<?  
include($include_path.'/inc/'.$_GET['page'].'-'.$_SESSION['lang'].'.php');  
?>  
  
...  
  
  
- [B] Information Disclosure  
  
[-] Risk: medium  
[-] File affected: database.inc  
  
This file contains reserved informations such as  
the username and the password for connecting to  
the database. Using .inc extension only, the  
content is visible.  
  
- [C] Arbitrary File Upload  
  
[-] Risk: medium  
[-] File affected: product_image.php  
  
In the admin directory there are no files that  
check if the user has admin privileges. For this  
reason a guest can execute the files contained in  
this directory. product_image.php contains a form  
that allows to upload files on the system but  
does not contain functions that check the files  
extensions, however a user can upload arbitrary  
files.
