SYSTEMS AFFECTED
Netopia R9100 Router 4.6
PROBLEM
Julien Henry found following. This will be short because it does
not need a lot of explanation. This is in a really specific case.
If you have the password of the router and if you are logged to it
you will not be able to delete all the traces. The router logs
the connection and the disconnection of telnet sessions. If you
want to delete the connection from the logs you just have to
delete them. But if you want to delete the disconnection log you
can't.
The only way to do that is to make it crash. Just use the telnet
program which is inside the router. Try to make a connection from
the IP of the router to the IP of the router. It will crash it,
as a consequence, you will NOT be logged! In the log you only see
things like that:
