modem hacking

so how hacker use this CSRF attack To change Modem Password and Username lets do it step by step.
for doing this you just need to now what all parameter the cgi page is using.
now consider that you know the parameter that the reset successful page is taking after knowing those things you just need to create a html page that basically call that cgi/successful confirmation on the form action parameter and after doing it the password will successfully changed so i think you must have got some confused lets do it practically.

i am taking an example that is already submitted by one of my friend Prayas a Real quality security expert.
There is a CSRF vulnerability in the Buffalo WZR-HP-G300NH2(A high Speed wireless Modem) and any one easily change or manipulate the admin username and password. This is will POST request and any one can craft malicious html form with specially crafted POST request
to the router and on execution of the form the router's user name and password can be changed to anything.
