# Rôle utilisateur contrôlé par un paramètre

Notes sur le rôle utilisateur contrôlé par un paramètre pour les laboratoires de la PortSwigger Web Security Academy, incluant le workflow d’exploitation, les tests de payloads, la validation dans Burp Suite et le contexte de remédiation.

### Rôle de l’utilisateur contrôlé par un paramètre de requête

Ce laboratoire possède un panneau d’administration accessible via **/admin**, qui détermine si un utilisateur est administrateur sur la base d’un cookie **facilement falsifiable**. / L’objectif est d’accéder au panneau d’administration puis de supprimer l’utilisateur **carlos**. / Vous pouvez vous connecter avec les identifiants suivants : **wiener:peter**.

Après avoir modifié l’adresse e-mail, nous remarquons qu’un cookie indique simplement **vrai** ou **faux** le rôle d’administrateur.

En modifiant sa valeur en **vrai**, le panneau d’administration devient accessible.

# 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/web/access-control/user-role-controlled-by-a-parameter.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.
