CVE-2024-1464 in Elementor Addons Plugin
Summary
by MITRE • 04/09/2024
The Elementor Addons by Livemesh plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘style’ attribute of the Posts Slider widget in all versions up to, and including, 8.3.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The vulnerability CVE-2024-1464 affects the Elementor Addons by Livemesh plugin for WordPress, specifically targeting the Posts Slider widget functionality. This issue represents a critical security flaw that enables attackers to execute malicious scripts within the context of a victim's browser. The vulnerability exists in all plugin versions up to and including 8.3.4, making it a widespread concern for WordPress administrators who have not yet updated their installations. The flaw lies in the plugin's failure to properly sanitize and escape user input, creating an environment where malicious code can persist and execute without proper authorization.
The technical implementation of this vulnerability stems from insufficient input validation within the 'style' attribute processing of the Posts Slider widget. When authenticated users with contributor-level access or higher create or modify posts containing malicious scripts within this attribute, the plugin fails to adequately sanitize the input before storing it in the database. This stored data is then served to other users who access pages containing the affected widget, leading to the execution of malicious scripts in their browsers. The vulnerability operates as a classic stored cross-site scripting attack where the malicious payload is permanently stored and executed during normal page rendering operations. This represents a CWE-79 (Cross-site Scripting) vulnerability with specific implications for content management systems where user-generated content is processed and displayed.
The operational impact of this vulnerability is significant for WordPress sites utilizing the affected plugin. Attackers with contributor-level access can inject scripts that may steal user session cookies, redirect visitors to malicious websites, or perform actions on behalf of authenticated users. The privilege escalation aspect means that even users who should not have the ability to execute arbitrary code can leverage this vulnerability to compromise the site's security. This creates a potential for widespread damage including data theft, unauthorized content modification, and establishment of persistent backdoors within the WordPress environment. The vulnerability affects not just individual users but potentially entire WordPress installations that rely on the Elementor Addons plugin for their page building functionality.
Organizations and WordPress administrators should immediately update to the latest version of the Elementor Addons by Livemesh plugin to mitigate this vulnerability. The recommended mitigation strategy includes implementing proper input validation and output escaping mechanisms, which aligns with defensive programming practices outlined in the OWASP Top Ten and MITRE ATT&CK framework for web application attacks. Additionally, administrators should consider implementing role-based access controls to limit the privileges of users who can modify content, thereby reducing the attack surface for this specific vulnerability. Regular security audits and monitoring of user activities within the WordPress admin panel can help detect potential exploitation attempts before they cause significant damage. The vulnerability also highlights the importance of keeping all WordPress plugins up to date and following security best practices for content management systems.
