Exploits :
°°°°°°°°°°
- To be admin :
http://[target]/admin.php?loggedin=1


- To read config.php (with admin password, DB password,...) :
1) Set a cookie named "file" and with the value "config.php" on 
http://[target]/form.php
2) Fill the form on this form.php page (the image have to be a real image, 
.gif or .jpg !)
3) Submit the form
4) Go on the index, look at your file (the last registered image)
5) Read it : it's config.php.
