Xerox DocuTech problems

I'm forwarding this for people who would like to remain
anonymous.

This case illustrates why software product vendors should be
held legally and financially accountable for the security
problems caused by their reckless and sometimes arrogant
disregard of known problems.

Xerox replied with a document mirrored at
http://totally.righteous.net/jedgar/overview_of_security.pdf
which doesn't address many of the problems, and states that the
ultimate responsibility for security lies with the customer.

Kudos to Xerox for setting a new standard of incompetence.

The model is a Xerox DocuTech 6110 or 6115.

These puppies are not old-fashioned optical copiers but
basically two units, a high-speed scanner and a high speed laser
printer.

The laser printer is controlled by a dual-processor Sun Uitra 60
running Solaris 8. The Scanner is controlled by an Intel box
running Windows NT.

The scanner sends jobs via ftp to the printer. Jobs can also be
sent to the printer via lpd through a windows print driver or
other means.

So, they install it, first thing we do is ask what the root
password is for the Solaris box. "Oh, no problem, it's
"service!" -- it's the same for all of our machines."

WTF?  First thing I say is "We will want to change that."

"No, you can't. It will probably break things."

Well, this puppy is WIDE OPEN like you wouldn't believe.
Everything imaginable is running and listening, including such
arcane services like sprayd.  Then I do a "rpcinfo -p" and see a
shitload of unknown RPC services running. But best yet,
showmount -e reveals numerous directories exported to the entire
world, world writable!

The NT box Administrator account password is "administ" and is
wide open, so anyone can connect to C$. Copies of all jobs
scanned are saved in case they are needed to be rerun later, so
anyone wanting to grab that document doesn't have to wait for it
to appear in the spool dir of the Solaris box, just grab it from
the scanner box at your leisure.

Go to the server's http port and there's a complete web page
which is very helpful for allowing you to submit jobs over the
web and directly into the "print now" queue so an operator
doesn't even have to approve it before it prints out. Imagine
the fun you can have. Also, there's a very helpful job history
so you can see who has been copying what, all anonymous, no
authentication required.

So, we lock the box down tight, installing ssh, disabling
telnet, finger, echo, chargen, and other shit you wouldn't
believe. Also installed security updates from Microsoft on the
NT box.  Xerox comes in today and has a fit and starts to
reinstall everything from scratch.

And scanning for these puppies would be easy as pie. Just do a
finger against a block of addresses for xrxusr account and if it
replies, you got yourself one...
