CVE-2024-49631 is a stored cross-site scripting (XSS) vulnerability identified in the Easy Addons for Elementor plugin developed by Md Abdul Kader, affecting versions up to 1.5.0. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows malicious scripts to be stored and subsequently executed in the browsers of users visiting the compromised site. Stored XSS is particularly dangerous because the malicious payload persists on the server and is delivered to multiple users, increasing the attack surface. Attackers can exploit this flaw to execute arbitrary JavaScript code, potentially leading to session hijacking, theft of sensitive information, defacement of websites, or redirection to phishing or malware sites. The vulnerability does not require authentication or user interaction to be exploited once the malicious script is stored. Although no public exploits have been reported yet, the widespread use of the Elementor plugin ecosystem and the ease of exploitation make this a significant threat. The vulnerability was published on October 20, 2024, with no CVSS score assigned yet. The lack of a patch link indicates that a fix may not be available at the time of publication, underscoring the need for immediate attention by site administrators. The plugin is widely used in WordPress environments, which are common globally, especially in countries with large WordPress user bases. The vulnerability highlights the importance of proper input validation and output encoding in web applications to prevent injection attacks.

The impact of CVE-2024-49631 is considerable for organizations running websites with the Easy Addons for Elementor plugin. Successful exploitation can compromise the confidentiality and integrity of user sessions by enabling attackers to steal cookies, credentials, or other sensitive data. It can also affect availability indirectly by enabling attackers to deface websites or inject malicious redirects, damaging brand reputation and user trust. Since the vulnerability is stored XSS, it can affect all users who visit the compromised pages, amplifying the potential damage. Organizations in sectors such as e-commerce, finance, healthcare, and government that rely on WordPress sites with this plugin are particularly vulnerable to data breaches and phishing campaigns. The absence of a patch at the time of disclosure increases the window of exposure, necessitating immediate mitigation efforts. Additionally, attackers could leverage this vulnerability as a foothold for further attacks within the network or to distribute malware. The global reach of WordPress and Elementor means that the threat is not localized but widespread, affecting organizations of all sizes and industries worldwide.

1. Monitor for updates from the plugin vendor and apply patches immediately once available to remediate the vulnerability. 2. Until a patch is released, implement Web Application Firewall (WAF) rules to detect and block malicious input patterns targeting the vulnerable plugin components. 3. Conduct a thorough audit of all user-generated content fields handled by the Easy Addons for Elementor plugin and apply strict input validation and output encoding to neutralize potentially malicious scripts. 4. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 5. Regularly scan websites for XSS vulnerabilities using automated tools and manual penetration testing. 6. Educate site administrators and developers about secure coding practices, especially regarding input handling in WordPress plugins. 7. Restrict administrative access and monitor logs for suspicious activities that may indicate exploitation attempts. 8. Consider temporarily disabling or removing the Easy Addons for Elementor plugin if immediate patching is not feasible and the risk is deemed high.
