I've just found a hidden menu on my Linksys/Cisco E4200 router and made a search on google to find out if there are any other. So far I found the followings.

http://192.168.1.1/Cysaja.asp

Now I am trying to find others if exists any. The question is how?
I have some skills but I am not a hacker. What I will try is to implement basic code to try all possibilities (kind of brute force). However, I wonder if there is any other easy way to do it? Do you guys have any idea?
