Thanks all for your replies. Since posting this, I have reflashed the router with the latest firmware, directly from ASUS's website, and the flaw persists.I will try Craig's advice about contacting the tech support email.

You seem to have amazing patience when reporting such things. I am personally the type of person that will spend all day on the phone with a company until I reach someone who actually knows what I'm talking about & knows who to get ahold of! Until I get ahold of someone who is relevant I find it amazingly difficult to do anything else, it eats away at me until the problem is resolved. LOL. ---R.

The following week, I submitted another message to techsupport () asus 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.

It should be further noted, that setting a password for the telnet account
via the /sbin/chpasswd.sh script is only valid until the next reboot when it
gets wiped out.
After alerting ASUS, I got the following non-reply. They are not taking the
problem seriously (they just closed out the ticket with a generic response):

Subject: [Full-disclosure] ASUS RT-N13U Unsecured Telnet on LAN and WAN
The ASUS RT-N13U home router comes configured with an unsecured telnet for
user "admin".
Telnetting in with this user will result in a root shell. The telnet is not
configurable from the web interface, nor does changing the password on the
web interface's admin user make any difference. I have alerted ASUS to the
problem on 10/25/13. I have been able to verify that this telnet interface
is visible from both the LAN and WAN.
Sincerely,
Shellster
