# XSS 源代码窃取
### Gitea 上的 XSS（v1.22.0）
在 `http://localhost:3000` -> **Gitea** 可访问。
使用 Axel 的凭据建立连接。
已知的 XSS 漏洞。
我们创建一个项目，其描述包含：
```bash
XSS 测试
```
* 结果：
### 通过 LinPEAS 拦截的邮件
电子邮件内容：
* jobert\@localhost 必须验证 Gitea 仓库
我们发送一个包含脚本外传的 XSS 链接，该脚本读取页面内容 `index.php` 从 Gitea 仓库中，先将其编码为 Base64，然后发送到我们的 Web 服务器
{% code overflow="wrap" %}
```bash
已入侵
```
{% endcode %}
#### 通过我们的 Web 服务器
```bash
python -m http.server 8080
```
#### 外传内容（Base64 解码后）：
```bash
echo "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%2FPgoK" | base64 -d

## 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-vulnerabilities/owasp-top-10-vulnerabilities/vulnerability-cross-site-scripting-xss/xxs-source-code-theft.md?ask=&goal=
```
`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.
