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

[Shelby Spencer <pwd_manager () hotmail com>]

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.

That's good news that the newer firmware does not share this issue, but they should patch the old firmware too!

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.

I received the same automated response when reporting a handful of

security flaws to Asus.  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.
