Imagine waking up to find your WordPress site compromised, with malicious plugins silently installed, giving attackers control over your website. This nightmare scenario is becoming a reality due to a Hunk Companion plugin vulnerability exploited by cybercriminals targeting the Hunk Companion plugin.
This critical flaw, identified as CVE-2024-11972, has a near-maximum CVSS score of 9.8 and impacts all versions of the plugin prior to 1.9.0.
With over 10,000 active installations of the plugin, the threat is widespread, leaving countless sites vulnerable to attacks such as Remote Code Execution (RCE) and SQL Injection.
Key Takeaway to the Hunk Companion Plugin Vulnerability:
- Staying vigilant and keeping plugins updated is essential to protect your WordPress site from vulnerabilities.
The Critical Flaw in the Hunk Companion Plugin Vulnerability
What Is CVE-2024-11972?
CVE-2024-11972 is a high-severity vulnerability in the Hunk Companion plugin. The flaw allows unauthenticated users to bypass security checks and install unauthorized plugins. Exploiting this flaw can enable attackers to:
- Execute malicious PHP scripts.
- Create administrative backdoors.
- Tamper with database records.
How Does the Exploit Work?
The vulnerability originates in the script “hunk-companion/import/app/app.php,” which fails to verify user permissions before installing plugins.
This oversight enables attackers to exploit the flaw remotely, posing a severe risk to WordPress site owners.
Real-Life Exploit: Weaponizing the Flaw
WPScan uncovered this vulnerability when analyzing a hacked WordPress site. Threat actors used the flaw to install a now-removed plugin, WP Query Console, which has its own zero-day RCE vulnerability (CVE-2024-50498, CVSS 10.0).
Attackers exploited this flaw to execute malicious code.
The exploit chain demonstrates the critical danger of unpatched vulnerabilities and outdated plugins.
Why This Vulnerability Matters
Impact of the Exploit
When attackers exploit a WordPress plugin vulnerability, they can:
- Gain unauthorized access to your site.
- Steal sensitive data.
- Redirect visitors to malicious websites.
A Pattern of Exploitation
This isn’t the first time a WordPress plugin has been weaponized. In 2022, a similar vulnerability in the Elementor plugin affected millions of websites, leading to widespread attacks.
Protecting Your WordPress Site
To safeguard your website, follow these actionable steps:
- Update All Plugins Regularly: Ensure your plugins, including Hunk Companion, are updated to the latest versions.
