CVE-2024-47375 identifies a stored cross-site scripting (XSS) vulnerability in the webangon XLTab – Accordions and Tabs for Elementor Page Builder plugin, specifically versions up to 1.3. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be stored persistently within the plugin's data. When a victim accesses a page containing the injected payload, the malicious JavaScript executes in their browser context. This can lead to a range of attacks including session hijacking, theft of cookies or credentials, defacement, or unauthorized actions performed on behalf of the user. The vulnerability is particularly dangerous because it is stored XSS, meaning the malicious code remains on the server and affects all users viewing the compromised content. The plugin is widely used in WordPress environments that utilize the Elementor Page Builder, a popular tool for building websites. Although no known exploits have been reported in the wild yet and no official patches have been released, the vulnerability is publicly disclosed and thus could be targeted by attackers. The lack of a CVSS score requires an assessment based on the nature of the vulnerability, which indicates a high severity due to the potential impact and ease of exploitation without authentication. The vulnerability affects the confidentiality and integrity of user data and could also impact availability if leveraged for further attacks. The plugin’s user base includes a broad range of organizations, from small businesses to larger enterprises relying on WordPress for content management and customer engagement.

The primary impact of CVE-2024-47375 is on the confidentiality and integrity of users interacting with websites using the vulnerable XLTab plugin. Attackers exploiting this stored XSS vulnerability can execute arbitrary JavaScript in the context of any user visiting the affected pages, potentially stealing session cookies, redirecting users to malicious sites, or performing unauthorized actions on behalf of users. This can lead to compromised user accounts, data breaches, and reputational damage for affected organizations. Additionally, if attackers inject scripts that perform destructive actions or spread malware, the availability of the website could be impacted. Organizations with high-traffic websites or those handling sensitive user information are at greater risk. The vulnerability also poses a risk to website administrators and content editors who may inadvertently trigger malicious scripts. Since the plugin is integrated into WordPress sites using Elementor, a widely adopted page builder, the scope of affected systems is significant, spanning multiple industries and geographies. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as public disclosure increases awareness among attackers.

Organizations should monitor for official patches or updates from the webangon vendor and apply them promptly once available. Until a patch is released, administrators should restrict or sanitize user input fields that interact with the XLTab plugin to prevent injection of malicious scripts. Employing a robust web application firewall (WAF) with specific rules to detect and block XSS payloads can provide an additional layer of defense. Website owners should review and audit content generated by the plugin for suspicious or unauthorized scripts. Implementing Content Security Policy (CSP) headers can help mitigate the impact of XSS by restricting the execution of inline scripts and external resources. Regular security scanning and penetration testing focused on XSS vulnerabilities are recommended to identify and remediate similar issues proactively. Educating content editors and administrators about the risks of XSS and safe content management practices can reduce accidental exploitation. Finally, maintaining up-to-date backups ensures recovery options in case of compromise.
