CVE-2024-56254 is a stored cross-site scripting (XSS) vulnerability found in the Move Addons for Elementor WordPress plugin, specifically in versions up to 1.3.6. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows an attacker to inject malicious JavaScript code that is stored persistently on the affected website. When other users visit the compromised page, the malicious script executes in their browsers under the context of the vulnerable site. This can lead to a range of attacks including session hijacking, credential theft, unauthorized actions on behalf of users, and defacement of the website. The vulnerability does not require authentication or user interaction beyond visiting the infected page, making it easier to exploit. Move Addons for Elementor is a widely used plugin that extends the Elementor page builder, which itself is one of the most popular WordPress page builders globally. The lack of a CVSS score means severity must be assessed based on impact and exploitability factors. No patches or exploit code are currently publicly available, but the vulnerability has been officially published and should be addressed promptly. The issue highlights the importance of proper input validation and output encoding in web applications, especially in widely deployed CMS plugins.

The impact of CVE-2024-56254 is significant for organizations using WordPress sites with the Move Addons for Elementor plugin. Successful exploitation allows attackers to execute arbitrary JavaScript in the context of the vulnerable site, potentially leading to theft of cookies, session tokens, and other sensitive information. This can facilitate account takeover and unauthorized access to user data. Additionally, attackers can perform actions on behalf of authenticated users, inject phishing content, or deface websites, damaging brand reputation and user trust. Because the vulnerability is stored XSS, the malicious payload persists and can affect multiple visitors over time. The ease of exploitation without authentication or complex prerequisites increases the risk of widespread attacks. Organizations hosting customer-facing websites, especially those handling sensitive user data or financial transactions, face elevated risks. The vulnerability could also be leveraged as a foothold for further attacks within a compromised environment.

To mitigate CVE-2024-56254, organizations should immediately update Move Addons for Elementor to the latest version once a patch is released. Until then, consider disabling or removing the vulnerable plugin to eliminate exposure. Implementing a Web Application Firewall (WAF) with rules to detect and block XSS payloads can provide temporary protection. Review and sanitize all user inputs rigorously, especially those that are reflected or stored and rendered in web pages. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Regularly audit plugins and themes for vulnerabilities and maintain an inventory of installed components. Monitor web server logs for suspicious activity indicative of XSS exploitation attempts. Educate site administrators and developers about secure coding practices, focusing on input validation and output encoding. Finally, conduct penetration testing or vulnerability scanning to identify and remediate similar issues proactively.
