CVE-2024-47628 is a stored cross-site scripting (XSS) vulnerability identified in the LA-Studio Element Kit for Elementor, a WordPress plugin that extends Elementor page builder functionality. The vulnerability exists due to improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be injected and stored persistently within the website's content. When other users or administrators visit the affected pages, the malicious scripts execute in their browsers, potentially leading to session hijacking, credential theft, unauthorized actions, or malware distribution. The affected versions include all releases up to and including 1.3.9.3. Exploitation requires no authentication or special privileges, making it accessible to unauthenticated attackers who can submit crafted input to the vulnerable plugin's input fields. Although no public exploits are currently known, the vulnerability's nature and the widespread use of Elementor and its extensions make it a significant risk. The absence of a CVSS score necessitates a severity assessment based on the impact on confidentiality, integrity, and availability, ease of exploitation, and scope of affected systems. Stored XSS vulnerabilities are particularly dangerous because they can affect all visitors to a compromised site and can be used as a vector for further attacks. The vulnerability was published on October 5, 2024, with no patch links currently available, indicating that users should monitor vendor announcements for updates.

The impact of CVE-2024-47628 is substantial for organizations using the LA-Studio Element Kit for Elementor on their WordPress sites. Successful exploitation can lead to the execution of arbitrary JavaScript in the context of the affected website, enabling attackers to steal session cookies, perform actions on behalf of authenticated users, deface websites, or distribute malware. This compromises the confidentiality and integrity of user data and can damage organizational reputation. Since the vulnerability is stored XSS, it affects all visitors to the compromised pages, potentially amplifying the attack's reach. E-commerce sites, membership portals, and any sites handling sensitive user information are particularly at risk. Additionally, attackers can leverage this vulnerability as a foothold for further attacks within the organization's network or to pivot to other systems. The lack of authentication requirements lowers the barrier to exploitation, increasing the likelihood of attacks once the vulnerability becomes widely known. Organizations worldwide that rely on Elementor and its extensions for website functionality face potential service disruption and data breaches if this vulnerability is exploited.

To mitigate CVE-2024-47628, organizations should immediately audit their use of the LA-Studio Element Kit for Elementor plugin and restrict or sanitize all user inputs that interact with this plugin. Until an official patch is released, consider disabling or removing the plugin if feasible. Implement web application firewalls (WAFs) with rules designed to detect and block XSS payloads targeting known plugin endpoints. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected web pages. Regularly monitor website content for unauthorized script injections or defacements. Educate site administrators and users about the risks of XSS and encourage the use of strong authentication and session management practices to reduce the impact of potential session hijacking. Once a patch is available from LA-Studio, prioritize its deployment across all affected systems. Additionally, conduct penetration testing and vulnerability scanning focused on XSS to identify and remediate similar issues proactively.
