How to Fix CVE-2024-10960: An Arbitrary File Upload Vulnerability in Brizy WordPress Page Builder Plugin?
The Brizy – Page Builder plugin for WordPress is a popular tool, but recently, a critical vulnerability has been identified that demands immediate attention from security professionals. This article delves into CVE-2024-10960, an arbitrary file upload vulnerability affecting versions up to and including 2.6.4. We will provide a detailed overview of the vulnerability, its potential impact, and, most importantly, clear guidance on how to mitigate the risk and secure your WordPress sites. This guide is tailored for DevSecOps engineers, application security specialists, vulnerability management teams, penetration testers, and security operations personnel who need to understand and address this threat effectively.
A Short Introduction to the Brizy WordPress Page Builder Plugin
Brizy is a user-friendly WordPress page builder plugin designed to simplify the process of creating website layouts and content. It offers a visual, drag-and-drop interface that allows users to build complex pages without requiring coding knowledge. Brizy is known for its intuitive design, pre-built templates, and responsive design capabilities, making it a popular choice for both novice and experienced WordPress users. However, like any software, it is susceptible to vulnerabilities, and CVE-2024-10960 is a prime example of why security vigilance is crucial.
Summary of CVE-2024-10960
CVE ID: CVE-2024-10960
Description: Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in the Brizy – Page Builder plugin for WordPress.
CVSS Score: 9.9 (Critical)
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
The Brizy – Page Builder plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'storeUploads' function. This vulnerability affects all versions up to, and including, 2.6.4. This allows authenticated attackers with Contributor-level access and above to upload arbitrary files on the affected site's server. The absence of proper file type validation means that malicious actors can bypass security measures by uploading files with dangerous extensions (e.g., .php, .exe, .sh) or disguised as legitimate file types, potentially leading to remote code execution.
Impact of CVE-2024-10960
The impact of CVE-2024-10960 is severe, as it can lead to remote code execution (RCE) on affected WordPress sites. An attacker with Contributor-level access or higher can exploit this flaw to upload malicious files to the server. Once uploaded, these files can be executed, potentially granting the attacker full control over the server.
This level of access can result in:
Data Theft: Sensitive information, including user data, financial records, and proprietary business information, can be stolen.
Website Defacement: The website can be altered or replaced with malicious content, damaging the organization's reputation.
Further System Compromise: The compromised server can be used as a launchpad for attacks on other systems within the network.
Malicious Use: The server can be used for hosting malware, participating in botnet activities, or other illicit purposes.
Therefore, addressing this vulnerability is critical to protecting the integrity, confidentiality, and availability of WordPress-based systems. You can consider a Patch Management strategy to remediate such vulnerabilities.
Products Affected by CVE-2024-10960
The following product versions are affected by this vulnerability:
|
Product

Brizy – Page Builder (WordPress Plugin)
|
Up to and including 2.6.4
|
It is important to note that any WordPress site using the Brizy – Page Builder plugin with a version equal to or lower than 2.6.4 is potentially vulnerable. There is no information about non-affected products or exempted products. Organizations must verify their installed version of the Brizy plugin to determine their exposure to this vulnerability.
How to Check Your Product is Vulnerable?
Determining whether your WordPress site is vulnerable to CVE-2024-10960 involves a few straightforward steps:
1. Check the Plugin Version:
Log in to your WordPress admin dashboard.
Navigate to the "Plugins" section.
Locate the "Brizy – Page Builder" plugin in the list.
Check the version number displayed beneath the plugin name. If the version is 2.6.4 or lower, your site is vulnerable.
2. Audit User Roles:
Review the users on your WordPress site and their assigned roles.
Identify users with "Contributor" or higher-level access (e.g., Author, Editor, Administrator). These accounts could be exploited to upload malicious files.
3. Monitor File Upload Activity:
Examine server logs for any unusual file upload activities, especially to directories associated with the Brizy plugin.
Look for uploads of files with suspicious extensions or filenames.
4. Web Application Firewall (WAF) Logs:
If you have a WAF in place, review its logs for any blocked or suspicious file upload attempts targeting the Brizy plugin.
5. Identify potential exploitation attempts:
Monitor server logs for POST requests to file upload endpoints commonly used by Brizy, especially if they contain unusual file extensions or large file sizes.
Set up alerts for any unauthorized modifications to Brizy plugin files or directories.
Correlate file upload events with user login activity to identify suspicious patterns.
By proactively monitoring your system and checking these indicators, you can quickly assess whether your WordPress site is vulnerable to CVE-2024-10960 and take appropriate action. Threat Intelligence can also help to proactively identify potential threats and vulnerabilities.
How to Fix the Vulnerability?
The primary remediation strategy for CVE-2024-10960 is to update the Brizy – Page Builder plugin to a version higher than 2.6.4. Here's a step-by-step guide on how to do so:
1. Update the Plugin:
Log in to your WordPress admin dashboard.
Navigate to the "Plugins" section.
Locate the "Brizy – Page Builder" plugin.
If an update is available, you will see an "Update Now" link. Click it to initiate the update process.
Alternatively, you can go to "Dashboard" -> "Updates" and update all available plugins, including Brizy.
If an automatic update isn't possible or available, you can manually update the plugin:
1. Manual Update:
Download the latest version of the Brizy – Page Builder plugin from the official WordPress plugin repository (wordpress.org).
Deactivate the current version of the plugin on your WordPress site.
Delete the existing Brizy plugin directory from your server via FTP or a file manager.
Upload the new version of the plugin to the
wp-content/plugins/directory.Activate the new version of the plugin through the WordPress admin dashboard.
Additional Security Measures:
Even after updating the plugin, it is crucial to implement additional security measures to protect your WordPress site:
1. Implement Strict Access Controls:
Limit the number of users with Contributor-level access or higher.
Regularly audit user accounts and remove unnecessary privileges.
2. Web Application Firewall (WAF):
Implement a WAF to detect and prevent file upload attacks.
Configure the WAF to block uploads of files with dangerous extensions.
3. Regular Monitoring:
Monitor server logs for any suspicious file upload activities.
Set up alerts for unusual behavior.
4. Disable the Plugin (If Necessary):
If the risk is deemed too high for your environment, consider disabling the Brizy – Page Builder plugin until a patched version is available.
5. Content Security Policy (CSP):
Implement a strict Content Security Policy (CSP) to limit the sources from which resources can be loaded, reducing the risk of executing malicious code. Consider understanding indicator of compromise (IOC).
By combining the plugin update with these additional security measures, you can significantly reduce the risk of exploitation and protect your WordPress site from the arbitrary file upload vulnerability.
Organizations should monitor official channels for any security updates or patches related to this vulnerability. A SOAR platform can help automate threat detection and incident response.
