Input passed to the "base_dir" is not properly verified 

before being used to include files. This can be exploited to execute 
arbitrary PHP code by including files from local or external resources.

code from login.php

<?php
define('PHPCC', true);
define('SITE', 'login.php');

include($base_dir."includes/common.php");
include($base_dir."includes/header.php");

switch( $_GET['action'] )

code from reactivate.php

define('PHPCC', true);

include($base_dir."includes/config.php");
include($base_dir."includes/constants.php");
include($base_dir."includes/functions.php");
include($base_dir.'includes/sessions.php');

if( $_POST['submit'] == true )

code from register.php

<?php
define('PHPCC', true);
define('SITE', 'register.php');

include( $base_dir . "includes/common.php" );
include( $base_dir . "includes/header.php" );

Google dork : "Powered by phpCC Beta 4.2"
