Scenario:<br>
<br>
An ISP offers pre-configured ADSL routers to suit its ADSL lines.<br>
<br>
Before shipping the router, as well as setting up the line parameters and<br>
login, the ISP makes some hidden configuration changes to the router.<br>
<br>
By default the router offers configuration through its internal LAN<br>
interface, by means of either http or telnet - i.e. you can use either a<br>
web browser or a telnet client to configure it. The web configuration<br>
interface is a bit limited - anything really sophisticated needs the CLI.<br>
In addition the router offers the user the option to open up remote<br>
administration for a limited period. That is, the router will offer its<br>
http interface on an unusual port on its external (WAN) interface at the<br>
request of an internal administrator.<br>
<br>
However, the ISP as part of the configuration changes permanently opens up<br>
both http and cli interfaces on the external interface of the router, on<br>
the standard ports 80 and 22. This change cannot be seen from the web<br>
interface, which still insists that external administration is disabled,<br>
and the configuration change is not mentioned in any documentation supplied<br>
with the router. The sole protection is password-based login, over<br>
unencrypted connections.<br>
<br>
I nearly fell off my chair when I discovered this. Am I over-reacting?<br>
