For those of you that have a SMC 7004FW, 7008ABR or some other
Barricade series soho router:

A remote admin page is open to the internet by default on port 1900. 
So, from the internet,
opening up http://YourInternetIpAddress:1900/   web page brings you to
the logon page for your router.  If you did not set a password, your
router is wide open.  This hole is even there if Remote Administration
is turned off and UPnP is turned off (1900 is the SSDP part of UPnP). 
Power off/on your router before testing because this flaw   disappears
under some configurations until a power reset.

The way to fix it seems to be 
  - enable the firewall - it is off by default
  - forward port 1900 to an unused IP address
  - the latest firmwares 2.15t2 and 2.16 both exhibit this hole

For further details, a discussion can be followed at
BroadBandReports.com via the following google search:

SMC was aware of this issue in the 7008ABR back in April and i heard
they fixed it with the latest firmware.  I informed them of the
problem with the 7004FW today.
