The vulnerability identified as CVE-2024-35702 represents a critical security flaw in the Jewel Theme Master Addons for Elementor plugin, specifically targeting the improper neutralization of input during web page generation processes. This weakness manifests as a stored cross-site scripting vulnerability that enables attackers to inject malicious scripts into web pages viewed by other users. The vulnerability exists within the Master Addons for Elementor plugin version range from an unspecified starting point through version 2.0.6.0, indicating that all versions within this range are potentially susceptible to exploitation.
The technical flaw stems from inadequate input validation and sanitization mechanisms within the plugin's codebase, particularly when processing user-generated content or configuration data that gets rendered into web pages. When users create or modify content through the Elementor page builder interface, the plugin fails to properly sanitize or escape data before storing it in the database and subsequently rendering it on web pages. This allows malicious actors to inject script payloads that persist in the system and execute whenever affected pages are accessed by other users. The stored nature of this vulnerability means that the malicious code remains embedded in the application's database and continues to propagate until manually removed or patched.
The operational impact of this vulnerability extends beyond simple script execution, as it provides attackers with the capability to perform various malicious activities including session hijacking, credential theft, data exfiltration, and potential privilege escalation within the affected WordPress environment. Attackers can leverage this vulnerability to steal administrator credentials, modify website content, redirect users to malicious sites, or even establish persistent backdoors within the compromised system. The vulnerability directly maps to CWE-79, which specifically addresses Cross-site Scripting flaws in web applications, and aligns with ATT&CK technique T1566.001 for initial access through malicious content. Given that Elementor is a widely used page builder plugin, the potential attack surface is extensive, affecting numerous websites that rely on this functionality for content management.
Mitigation strategies should prioritize immediate patching of the affected plugin to the latest available version that addresses this vulnerability. System administrators should also implement additional defensive measures including input validation at multiple layers, content security policies to restrict script execution, and regular security audits of plugin installations. Monitoring for unusual user activity and implementing web application firewalls can provide additional protection layers. Organizations should conduct comprehensive security assessments of their WordPress environments to identify other potentially vulnerable plugins or themes. The vulnerability also highlights the importance of maintaining updated security practices, including regular plugin updates, proper access controls, and monitoring for suspicious activities that could indicate exploitation attempts.
