FYI: AOLserver 3.0 vulnerability:
http://www.arsdigita.com/bboard/q-and-a-fetch-msg?msg_id=000hNB
However, the exploit script therein causes no damage at all when run against my local OpenACS 3.2.5 installation, which uses AOLserver 3.3+ad13.
Is it possible that this problem was fixed in AOLserver 3.3 as well as in 3.3.1?
