  - CVE-2016-20033: Local privilege escalation by replacing executable files

  - CVE-2016-20034: The application suffers from a privilege escalation issue. Normal user
  (read-only) can elevate his/her privileges by sending a POST request setting the parameter
  'accessLevel' to 'admin' gaining admin rights and/or setting the parameter 'advUser' to 'true'
  and '_advUser' to 'on' gaining advanced admin rights.

  - CVE-2016-20035: The application interface allows users to perform certain actions via HTTP
  requests without performing any validity checks to verify the requests. This can be exploited to
  perform certain actions with administrative privileges if a logged-in user visits a malicious web
  site.

  - CVE-2016-20036: Wowza Streaming Engine suffers from multiple reflected cross-site scripting
  vulnerabilities when input passed via several parameters to several scripts is not properly
  sanitized before being returned to the user. This can be exploited to execute arbitrary HTML and
  script code in a user's browser session in context of an affected site.");
