# 🔐 CVE-2023-32243 – Detection and Mitigation in WordPress

## 📘 Project Title:
**Detection and Mitigation of CVE-2023-32243 in the Essential Addons for Elementor WordPress Plugin**



## 🧠 Abstract
This project explores the exploitation and prevention of **CVE-2023-32243**, a critical **privilege escalation vulnerability** (CVSS score: 9.8) that affects the "Essential Addons for Elementor" plugin (versions 5.4.0 to 5.7.1) in WordPress. The vulnerability allows unauthenticated attackers to reset administrator passwords, thereby gaining full access to the WordPress backend.

We conducted a full-cycle security architecture simulation including:
- Vulnerability exploitation via a public proof-of-concept (PoC)
- Detection through security tools and alert systems
- Implementation of layered mitigations
- Documentation and demonstration within a controlled virtual machine (VM) environment

## 🏗️ Project Goals
- Simulate the exploitation of CVE-2023-32243 in a safe testbed.
- Implement a layered security strategy involving detection, alerting, and mitigation.
- Evaluate plugin behavior and security posture pre- and post-hardening.
- Demonstrate practical security administration in a WordPress context.

## 🖥️ Environment Setup
A virtual lab was created to replicate real-world hosting conditions using the following stack:

- **Operating System**: Ubuntu 22.04 (hosted in VirtualBox)
- **Web Stack**: LAMP (Linux, Apache, MySQL, PHP)
- **CMS**: WordPress with the affected plugin version (5.4.6 of Essential Addons for Elementor)
- **Security Plugins**:
  - [Wordfence](https://www.wordfence.com) – for MFA, WAF, live traffic, and audit logs
  - [WP Mail SMTP](https://wpmailsmtp.com) – for real-time email alerts
- **Exploit Source**: [PoC script on GitHub](https://github.com/gbrsh/CVE-2023-32243)
- **SMTP Integration**: Gmail API via Google Cloud Console
### 📺 Project Demonstration Video
A full walkthrough of the detection and mitigation process is available here:
▶️ [Watch on YouTube](https://youtu.be/00GRb59zLnw?si=QXSPSB7G7FjvrL5e)
## 🛡️ Detection Strategies
1. **Live Traffic Monitoring** (Wordfence)  
2. **Audit Logging** (Wordfence)  
3. **Email Alerts** (WP Mail SMTP)

## 🔐 Mitigation Techniques
1. **Multi-Factor Authentication (MFA)**
2. **Web Application Firewall (WAF)**
3. **User Hardening**
4. **Plugin Update Awareness**

## 🧪 Demonstration Summary
- The **PoC Python script** was used to exploit the vulnerability.
- **Wordfence** detected login from an unknown IP.
- **WP Mail SMTP** sent multiple email alerts.
- MFA blocked unauthorized access even after a password reset.

## 🔍 Limitations
- Reliance on third-party plugins
- Limited WAF functionality on free-tier
- Manual real-time incident handling
