phpMyVisites Arbitrary File Access
------------------------------------------------------------------------
SUMMARY
" <http://www.phpmyvisites.net/> phpMyVisites is a free and powerful open
source application for websites statistics and audience measurements."
Due flaws in user data validation, a remote user can retrieve locally
stored files on the system phpMyVisites is running on.
DETAILS
Vulnerable Systems:
* phpMyVisites version 1.3
Vulnerable code in file include/set_lang.php line 94:
include "./langs/".$lang['default_lang'];
assuming, $lang['default_lang'] was set on line 66:
$lang['default_lang'] = $_COOKIE[$nomcookielg];
line 40:
setcookie($nomcookielg, $_POST['mylang'], time()+3600*24*365*10);
Now, its possible to spoof the value of $_POST['mylang'] and point it to
any file we desire.
