~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Product: mediabox404 WebRadio & WebTV manager
Version: 1.2 Release (and previous)
URL: http://www.mediabox404.org
VULNERABILITY CLASS: SQL injection
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[PRODUCT DESCRIPTION]
This is a group of modules(administration, client, programmation, diffusion) in 
PHP/MySQL database that allows a webradio to manage their playlists, and so 
on...

[VULNERABILITY]

Vulnerable script: admin/login_admin_mediabox404.php

[code]

$requete=requete("select Pseudo from t_user where Pseudo='".$User."' and 
Passe='".$Password."'");

if(mysql_num_rows($requete)==0)
{
        header("Location:login_admin_mediabox404.php?Fct=Bad_Pseudo");
}
else
{

[/code]

In case magic_quotes_gpc=0, an attacker can inject SQL statements through $User 
parameter.

Example of exploitation:
In the login form type "existing_username' or 1 = 1 or Passe='a" in the "User" 
field and "whatever" in the "Password" field (without double quotes).

After the login bypass, the attacker can administrate the WebRadio. 


[Bugfix]:

[code]

 if (get_magic_quotes_gpc()) {
       $User = stripslashes($User);
       $Password = stripslashes($Password);
 }
 
 $sql_requete= sprintf("select Pseudo from t_user where Pseudo='%s' and 
Passe='%s'",
                mysql_real_escape_string($User), 
mysql_real_escape_string($Password));
 $requete=requete($sql_requete);

[/code]
