How to Scan Vulnerabilities on WordPress Using VirtualBox (2026 Guide)

With more than forty per cent of the world’s websites powered by WordPress, it has become a major target for cybercriminals. Its widespread use, combined with thousands of third-party plugins and themes, creates multiple entry points for attackers. Common threats include brute-force attacks, malware injections, SQL injections, and data breaches. For any WordPress website owner, maintaining strong security is essential not only to protect data but also to preserve user trust and search engine rankings.

One of the most effective ways to identify vulnerabilities is through penetration testing. By using security tools within a virtual environment such as VirtualBox, you can safely simulate real-world attacks and detect weaknesses before they are exploited. This approach allows you to test configurations, analyse risks, and improve security without impacting your live website.

In this guide, we will walk through a structured process to scan vulnerabilities on WordPress using VirtualBox. This includes setting up a virtual machine, installing penetration testing tools, running scans, and interpreting the results to strengthen your website’s security.

Why Use VirtualBox for WordPress Security Testing?

VirtualBox is a free and open-source virtualization platform that allows you to run multiple operating systems on a single physical machine. It is widely used by developers and security professionals to create isolated testing environments.

Benefits of Using VirtualBox for WordPress Security Testing

Safe Testing Environment

VirtualBox enables you to perform vulnerability assessments in a completely isolated setup. This ensures that your live website and production environment remain unaffected during testing.

Isolated and Controlled Setup

You can build a dedicated testing lab where your WordPress installation and security tools run together without interfering with your primary operating system. This minimizes risks and keeps your system stable.

Multiple Testing Scenarios

VirtualBox allows you to create and manage multiple virtual machines with different configurations. You can test various WordPress versions, plugins, themes, and server environments such as Apache or Nginx to identify a wide range of vulnerabilities.

Cost-Effective Solution

There is no need for additional hardware or expensive infrastructure. VirtualBox runs on your existing system, making it an efficient and budget-friendly option for security testing.

Snapshot and Rollback Capability

VirtualBox provides snapshot functionality, allowing you to save the current state of your virtual machine. If an issue occurs during testing, you can quickly restore the system to a previous state without rebuilding the environment.

Compatibility with Security Tools

VirtualBox supports penetration testing operating systems like Kali Linux and Parrot OS. These systems include powerful tools such as WPScan, Metasploit Framework, Nikto, and Burp Suite, which are essential for identifying vulnerabilities in WordPress VPS environments.

Offline Testing Capability

You can replicate your WordPress site locally within the virtual machine and perform security testing without requiring an active internet connection. This adds an extra layer of safety and control.

Importance of This Approach

Using a virtual environment for WordPress security testing allows you to take a proactive approach to cybersecurity. Instead of waiting for attacks to occur, you can identify and fix vulnerabilities in advance. This method improves your website’s security and enhances your understanding of potential threats and attack vectors.

By combining the flexibility of VirtualBox with advanced penetration testing tools, you can build a secure, scalable, and efficient testing environment that helps protect your WordPress website from evolving cyber threats.

Step 1: Set Up a Virtual Machine in VirtualBox

Before scanning for vulnerabilities, we need a virtual environment where we can install WordPress and security testing tools.

1. Install VirtualBox

First, download and install VirtualBox from the official site:
Download VirtualBox

After installing VirtualBox, also install the VirtualBox Extension Pack for additional features like USB support and network adapters.

2. Create a Virtual Machine (VM)

1. Open VirtualBox and click “New” to create a VM.
2. Set the VM name (e.g., WordPressPentest).
3. Select Ubuntu (recommended) or Kali Linux as the operating system.
4. Allocate at least 4GB RAM and 2 CPU cores.
5. Create a Virtual Hard Disk (at least 20GB).
6. Complete the VM setup and install the selected OS.

Step 2: Install WordPress on the virtual machine

To scan for vulnerabilities, we need a test WordPress site running inside the VM.

1. Install LAMP Stack (Linux, Apache, MySQL, PHP)

Run the following commands to set up a WordPress server:

bash
sudo apt update && sudo apt upgrade -y
sudo apt install apache2 mysql-server php php-mysql libapache2-mod-php php-cli unzip wget -y

2. Download & Install WordPress

bash
cd /var/www/html
sudo wget https://wordpress.org/latest.zip
sudo unzip latest.zip
sudo mv wordpress/* .
sudo rm -rf wordpress latest.zip
sudo chown -R www-data:www-data /var/www/html 

3. Set Up WordPress Database

bash
sudo mysql -u root -p

Inside the MySQL shell, run:

sql
CREATE DATABASE wordpress;
CREATE USER 'wp_user'@'localhost' IDENTIFIED BY 'strongpassword';
GRANT ALL PRIVILEGES ON wordpress.* TO 'wp_user'@'localhost';
FLUSH PRIVILEGES;
EXIT;

4. Complete WordPress Installation

• Open a web browser and go to  http://localhost your VM.
• Follow the on-screen setup, entering the database details you created.

Your WordPress test site is now running inside VirtualBox!

Step 3: Install WordPress Vulnerability Scanning Tools

There are many security tools available to scan WordPress for vulnerabilities. Below are some of the best options:

1. WPScan (Recommended)

WPScan is a WordPress security scanner that detects vulnerabilities in plugins, themes, and the WordPress core.

Install WPScan

bash
sudo apt install wpscan -y

Run WPScan Against Your WordPress Site

bash
wpscan --url http://localhost --enumerate vp,vt,u

Finds: Plugin vulnerabilities, outdated software, weak passwords, and more.

2. Nikto (Web Server Scanner)

Nikto scans for common security flaws in web servers, including misconfigurations and outdated software.

Install Nikto

bash
sudo apt install nikto -y

Run Nikto Against Your WordPress Site

bash
nikto -h http://localhost

Finds: Server misconfigurations, outdated Apache/PHP versions, and insecure headers.

3. Nmap (Network Vulnerability Scanner)

Nmap scans for open ports, firewall misconfigurations, and security flaws.

Install Nmap

bash
sudo apt install nmap -y

Run Nmap on Your WordPress Server

bash
nmap -sV -Pn localhost

Finds: Open ports, running services, and potential entry points for attackers.

Step 4: Analyze the Scan Results

After running these tools, review the scan results and take action on any vulnerabilities found.

Example WPScan Report Output:

less

[+] WordPress version: 5.8.3
[!] 1 Vulnerability found in the WordPress core:
    - CVE-2024-XXXX: Remote Code Execution Vulnerability
[+] Plugins found:
    - WooCommerce 7.1.2 (Outdated, Vulnerable)
    - Contact Form 7 5.6 (Up-to-date) 

How to Fix Common Vulnerabilities:

2. Update Plugins & Themes → Outdated plugins/themes are a security risk.
3. Remove Unused Plugins → Deactivate and delete unused plugins.
4. Enable Strong Passwords → Use a password manager to generate strong passwords.
5. Install Security Plugins → Use Wordfence or Sucuri for additional protection

Step 5: Secure Your WordPress Installation

After scanning for vulnerabilities, take these additional steps to improve security:

1. Hide WordPress Version

php

function remove_wp_version() {
    return '';
}
add_filter('the_generator', 'remove_wp_version');

Prevents attackers from easily identifying your WordPress version.

2. Disable XML-RPC to Prevent Brute Force Attacks

apache
<Files xmlrpc.php>
    Order Allow, Deny
    Deny from all
</Files>

Blocks hackers from exploiting XML-RPC for brute-force attacks.

3. Install an SSL Certificate

bash

sudo apt install certbot python-certbot-apache
sudo certbot --apache

Enforces HTTPS encryption for secure communication.
