Subject: More details on BID 11408 (3com 3cradsl72 wireless router)

Hi,

I'm writing regarding BID 11408. I have this router at home for my ADSL
connection. The software versions of my router are:

   Runtime Code Version 1.05 (Jan 27 2004 14:58:25) 
   Boot Code Version V1.3d 
   Hardware Version 01A 
   ADSL Modem Code Version 13.9.38 

(taken from http://192.168.2.1/index.stm)

Under this environment I describe the URL http://192.168.2.1/app_sta.stm
described in this BID not only discloses some critical information. After I
accessed this URL I could access the rest of the administrative web
interface of the router and view/change any parameter (WEP keys, IP
addresssing, firewall rules, dhcp server configuration....). After I access
this URL the router considers that I´m authenticated.

The router allows to configure if the router can be administered from the
external interface (internet). As a workarround users should turn off this
option. This restricts the vulnerability to internal only users, then
considering that this is a Wireless router the highest level of protection
should be used in the wireless configuration. I recommend using WPA-PSK and
deactivating the ESSID Broadcast option.

Kind regards,
Ivan Casado Ruiz
