If someone is logged on the web interface of the router, the attacker could  
bypass the login form by going straigt to the default page of administration.  
(The root page will ask for password)  
The vulnerability works from any IP address, the router seems to be 'free to access' from any IP  
when a legit user is logged in.  
You may setup a bot that checks if someone is logged and if so, download the configuration backup  
to obtain the password.
