Subject: Re: ASUS RT-N13U Unsecured Telnet on LAN and WAN

I received the same automated response when reporting a handful of
security flaws to Asus.  The following week, I submitted another
message to techsupport@...s.com and received a relevant response
within 24 hours.

On a side note, I checked a different (slightly newer) Asus router
with the most recent firmware and it is not affected -- telnet starts
and stops as expected per the setting in the HTTP UI, the password
remains the same as the admin password, and telnet is not externally
accessible unless the firewall is disabled.

Best Regards,
Craig Young
