CVE-2024-52387 is a stored Cross-site Scripting (XSS) vulnerability identified in the Liton Arefin Master Addons for Elementor plugin, a popular extension for the WordPress Elementor page builder. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be stored and later executed in the context of users visiting the affected site. This flaw affects all versions up to and including 2.0.9.9.4. The attack vector requires an attacker to have high privileges (e.g., administrative or editor access) to inject the malicious payload, and it also requires user interaction for the payload to execute. The vulnerability impacts confidentiality, integrity, and availability to a limited extent, as attackers can execute arbitrary scripts that may steal session tokens, manipulate page content, or perform actions on behalf of users. The CVSS v3.1 base score of 5.9 reflects a medium severity, considering the network attack vector, low attack complexity, but requiring privileges and user interaction. No public exploits are known at this time, but the vulnerability remains a significant risk for websites using this plugin, especially those with multiple users and high privilege roles. The vulnerability highlights the importance of proper input validation and output encoding in web applications to prevent stored XSS attacks.

The primary impact of this vulnerability is the potential for attackers with elevated privileges to inject malicious JavaScript code that is stored and executed in the browsers of users visiting the affected site. This can lead to session hijacking, defacement, unauthorized actions performed on behalf of users, and potential data leakage. For organizations, this could result in compromised user accounts, loss of customer trust, reputational damage, and potential regulatory penalties if sensitive data is exposed. The requirement for high privileges limits the attack surface to users with administrative or editorial roles, but insider threats or compromised accounts could be leveraged to exploit this vulnerability. Additionally, the need for user interaction means attackers must trick users into triggering the payload, which could be done via phishing or social engineering. Overall, the vulnerability can disrupt website integrity and availability, impacting business operations and user confidence.

Organizations should immediately update the Liton Arefin Master Addons for Elementor plugin to the latest patched version once available. In the absence of a patch, administrators should restrict plugin access to trusted users only and review user roles to minimize high privilege accounts. Implement strict input validation and output encoding on all user-supplied data fields within the plugin to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Regularly audit and monitor logs for suspicious activities indicative of XSS exploitation attempts. Educate users and administrators about phishing and social engineering tactics that could trigger stored XSS payloads. Consider deploying Web Application Firewalls (WAFs) with rules targeting XSS attack patterns specific to this plugin. Finally, conduct periodic security assessments and penetration testing focusing on plugin vulnerabilities to detect and remediate issues proactively.
