Subject:      Security flaw in Telocity's "Gateway Modem"
To: BUGTRAQ@SECURITYFOCUS.COM

Telocity provides DSL to their customers through what they call the Telocity
"Gateway Modem".
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)

The modems with the following are vulnerable:

Manuf. Date: August 3, 1999
Hardware: v02.00.02.00
OS Release: v01.02.13.02

Newer modems give a 403 Forbidden error.

An email was sent to Telocity on 2/12/2001 via their website describing the
problem, and urging them to provide customers tat have this modem with a new
one.
