Maybe not just any random attacker.

Depending on configuration the server may be setup to allow access from
other machines on the local network. (Check the access control list
stuff).

This, of course, probably never happens in the real world. I mean, it
would be too useful to be able to share a printer. So of course, it
wouldn't affect anyone. Adding a feature to allow it was probably just an 
exercise to see if they could do it. </sarcasm>

Remote access can also be given (via issue 1) by sending an email with an
image link that exploits the handling of variables, allowing execution of
commands on the local machine. This can then be used to further elevate  
privs via the issue you mentioned, or one of the other issues.
