The Hunk Companion Plugin Vulnerability: Why Over 10,000 WordPress Sites Are in Danger

In today’s digital world, how secure is your WordPress site? With cyberattacks becoming more sophisticated, vulnerabilities in popular plugins can open the door to devastating breaches. A recent report by WPScan has uncovered a serious flaw in the Hunk Companion plugin—a tool used by over 10,000 WordPress sites—that could leave your website exposed to Remote Code Execution (RCE) and other critical attacks. Let’s explore the details of this vulnerability and how you can protect your site.

The Hunk Companion Vulnerability Explained

The flaw, tracked as CVE-2024-11972 with a CVSS score of 9.8, allows attackers to install vulnerable plugins on affected WordPress sites without authentication. This is possible due to a bug in the plugin's script (located in hunk-companion/import/app/app.php), which fails to properly verify user permissions before allowing plugin installations. This vulnerability affects all versions of the plugin prior to 1.9.0.

Attackers can exploit this flaw to install outdated or abandoned plugins—such as WP Query Console, which has a known zero-day RCE vulnerability (CVE-2024-50498). Once installed, attackers can use the RCE bug to execute malicious PHP code, taking full control of the site. The ability to install malicious plugins silently is what makes this vulnerability particularly dangerous, as it gives cybercriminals full access without triggering alarms.

Why Is This a Serious Threat?

What makes CVE-2024-11972 especially dangerous is how it combines old and new vulnerabilities. The flaw essentially bypasses a previously patched vulnerability in the Hunk Companion plugin (CVE-2024-9707), allowing attackers to circumvent security measures. As WordPress is used by over 43% of all websites worldwide (according to Statista), vulnerabilities like this can have far-reaching consequences.

The ability to install insecure plugins opens up several attack vectors, including:

• Remote Code Execution (RCE): Attackers can run malicious code on your server.
• Cross-Site Scripting (XSS): Malicious scripts can be injected into your site, affecting visitors.
• SQL Injection: Attackers can access and manipulate your database.
• Backdoor Creation: Attackers can create hidden access points for ongoing control.

These attacks can lead to data theft, website defacement, and even full control over the WordPress site, which could have devastating financial and reputational consequences.

Key Statistics on Cybersecurity Risks

According to IBM’s Cost of a Data Breach Report (2024), the average cost of a data breach is now $4.45 million. This figure highlights the financial toll cyberattacks can have on businesses. For WordPress site owners, the risk is clear: vulnerabilities in popular plugins can lead to expensive and damaging breaches.

How to Protect Your WordPress Site

• Update Plugins Regularly: Ensure you are using the latest versions of all plugins, including Hunk Companion. Security patches are released frequently to address known vulnerabilities.
• Remove Unused Plugins: If a plugin is no longer maintained or necessary, remove it to reduce potential attack vectors.
• Use Security Plugins: Install trusted security plugins like Wordfence to scan for vulnerabilities and protect against attacks.
• Backup Your Website: Regular backups ensure you can quickly recover in the event of a successful attack.

The Way Forward

The Hunk Companion plugin vulnerability is a stark reminder of the importance of securing every component of your WordPress site. Cybercriminals are constantly targeting outdated and vulnerable plugins to exploit weaknesses. As cyber threats continue to evolve, keeping your site updated and using security tools is essential to avoid costly breaches.

• Update plugins regularly and remove unused ones to minimize risk.
• Implement security plugins and backup strategies to enhance protection.
