Telocity provides DSL to their customers through what they call the

In the modems, you can connect to them through your web browser to view
usage statistics, your assigned IP, the DHCP server IP (Modems IP),
Management's IP (Modem's IP, different than the previous), DNS IP, and the
hardware software version information.

In the older model modem, it is possible to remotely view the "Details"
section of the modem, thus reveling all the above mentioned information to
a possible intruder.  Telocity has numbered their gateways in sequential
order, so it would be possible to write a script that would search for
http://123.123.123.1/stats in a range of addresses.  Of course is the ever
interesting URL http://123.123.123.1/admin which prompts you for a
username/password combo to access what? (any information on this would be
great)

How is this a "security flaw"?  It displays your connection's status as well
as hardware information of your DSL modem.  This is really useful, especially
if you run a server off your Telocity DSL line.  It let's you check on your
connection remotely, so you can check status of your DSL from anywhere.  I
think this is a feature, rather than a bug.
