It is possible to inject scriptcode into the applications logfile without
authentication. Once the admin is viewing the logfile via the web interface, 
the scriptcode will be executed.

e.g.:

http://victim:8001/"/><script>alert(document.getElementsByTagName("PRE")[0].firstChild.data)</script>

By abusing this vuln it is possible to send the complete logfile to an evil host.
