  ==========================
  Vulnerability Description:
  ==========================
  
  The CMS Papoo Light Version has a persistent XSS vulnerability in its guestbook functionality and in its user-registration functionality.
  
  ==================
  Technical Details:
  ==================
  
  XSS-Vulnerability #1:
  
  Papoo Light CMS v6 provides the functionality to post comments on a guestbook via the following url: http://{target-url}/guestbook.php?menuid=6.
  
  The input fields with the id „author“ is vulnerable to XSS which gets stored in the database and makes that vulnerability persistent.

  <iframe src=“some_remote_source“></iframe>
  
  XSS-Vulnerability #2:
  
  People can register themselves on Papoo Light v6 CMS at http://{target-url}/account.php?menuid=2. Instead of using a proper username, an attacker can inject HTML and/or JavaScriptcode on the username input-field.
  
  Code gets written to the database backend then. Attacker only has to confirm his/her e-mail address to be able to login and spread the code by posting to the forum or the guestbook where the username is displayed.
  
  Payload-Examples:
  
  see above (XSS #1)
