The AS/400 security model allows for a very tight lockdown of the system, but some services (namely FTP and the databases) are insecure by design (if you have an account, you can escalate through these services.) The services behind the ports can be found through some easy googling, and the high ports are described in the following location: http://www-912.ibm.com/n_dir/nas4apar.NSF/c79815e083182fec862564c00079d117/fcc664db54c4c549862568720047b5fd?OpenDocument&Highlight=2,ii12227 I wont go into too much detail on how to exploit this machine, as i'm not very certain you are a qualified person for this. (Don't get me wrong, but i've seen too many "0wn3d" as/400 servers) Kind Regards, Enchanter_tim

Recently during pentest I found following ports open on one of AS400 box: 21, 23, 449, 8476, 8470, 8472, 8471, 8475, 8473, 8474 I have gathered necessary infromation about these ports. Is there any way by which we can use these ports to get into this box?You're dealing with a completeley different beast. :) I have tons of respect for the AS400 architecture - security model is very well done, but as usual that's only as good in the real world as those maintaining it. Looks like a pretty minumal config, no IFS or tomcat or sillyness, just terminal server, ftp, and telnet. If you can sniff that network segment for a while and you'll probably get a few useful passwords. Seems like so few '400 system operators want to install ssh services...
