In general terms we would say that yes the default is that a Cisco router with no access lists will allow all traffic to go through (assuming that it is correctly configured with IP addresses etc).

There might be some very specific cases where certain types of traffic do not work without special configuration - for example the router will not process SSH traffic until you have generated RSA keys.

But i believe that your question is intended to address the general behavior and so I would say that the answer is yes it allows all traffic through.

Just to clarify this, this would be SSH traffic to/from the router as a host, SSH traffic would normally transit a router like any other traffic or as Rick described, i.e.:
