I use WRT54g v4 (firmware v.4.20.8)and try to the following command.

But I didn't exploit my router.

When I captured the normal packet with ethereal,

I only saw "POST /apply.cgi ....."

When I captured the exploit packet with curl,

I didn't receive a reply packet according to the exploit request but I received TCP FIN/ACK.

Is not my WRT54g v4 vulnerable?
