Actually,
        that looks to be like the same firmware as certain intelligent
hubs with integrated Terminal/Printer server capabilities.. I have one
here on my LAN. The model in question is made my a company called
Microplex, and it's a discontinued model called the M208.

There is, however, quite a bit of documentation in the hub's manual about
setting a root password, and the importance of doing so.. don't know who
decided to use this same firmware in plotters/printers or what their
documentation is like, however it seems to come down to the general rule
of never leave a peripheral unpassworded on your network if you want to
avoid these sorts of problems (telnet proxy, etc..)

Aleph1,
        I apologize if this has be brought up before, but with the recent
post concerning the QMS 2060 printers and the length of time I have sat on this
(4 months) I figured it should be released.  I sent this information to OCE long
ago with  no response.  I am aware of the Intelligent Peripherals bulletin by
CIAC.

        I have a few plotters / printers under my audit umbrella and
noticed something interesting on an Oce' 9400 plotter.  The printer has the
ability to be a telnet proxy.  Where as a user can hop via telnet to other
hosts.  If the printer is not setup properly the connections will go unlogged.

         All that is needed is a valid DNS server setup in the plotter
configuration.

192.168.38.244:root> set sysinfo dns 192.168.38.100

And anyone can use the plotter as an anonymous telnet proxy.

Fix:

Enable passwords for the accounts on the plotter:

syntax: set user add <NAME>
         set user del <NAME>
         set user passwd <NAME> [<PASSWORD>]
         set user type <NAME> root|guest
         set user from default|stored

Enable logging:

syntax: set logpath <LOGPATH> name <NEW_NAME>
         set logpath <LOGPATH> type [[-]job] [[-]user] [[-]pgcnt] [[-]cksum]
                     [[-]printer] [[-]ioport]
         set logpath <LOGPATH> port <TCP-PORT>|email|syslog
         set logpath from default|stored

P.S. This plotter has ping functionality also. No, I have not tried DoS attacks
=)

syntax: ping [-s] <IPNAME> [<DATASZ> [<NUMPKTS>]]
