CVE-2024-50543 identifies a DOM-based Cross-site Scripting (XSS) vulnerability in the 'amazing neo icon font for elementor' WordPress plugin developed by mudssar. This plugin, widely used to enhance Elementor page builder capabilities with icon fonts, improperly neutralizes user-supplied input during web page generation. Specifically, the vulnerability allows malicious actors to inject arbitrary JavaScript code into the DOM, which executes in the context of the victim's browser when they visit a crafted page or URL. This occurs because the plugin fails to sanitize or encode input that is dynamically inserted into the page, leading to a classic DOM-based XSS scenario. The affected versions include all releases up to and including 2.0.1. The vulnerability does not require authentication, increasing its risk profile, and can be exploited via social engineering techniques to lure users into clicking malicious links. Although no public exploits have been reported yet, the flaw is publicly disclosed and documented in the CVE database. The absence of a CVSS score indicates that the vulnerability is newly published and pending further assessment. The vulnerability primarily threatens the confidentiality and integrity of user sessions and data, as attackers can steal cookies, perform actions on behalf of users, or deface websites. The plugin’s widespread use in WordPress sites that utilize Elementor for page building amplifies the potential attack surface. The vulnerability is classified as a web application security issue, specifically related to improper input handling during dynamic content generation.

The impact of CVE-2024-50543 on organizations worldwide can be significant, especially for those relying on WordPress websites using the 'amazing neo icon font for elementor' plugin. Successful exploitation allows attackers to execute arbitrary JavaScript in users' browsers, leading to session hijacking, theft of sensitive information such as authentication tokens, and unauthorized actions performed on behalf of legitimate users. This can result in data breaches, defacement of websites, loss of customer trust, and potential regulatory penalties if personal data is compromised. E-commerce sites, membership portals, and any web applications handling sensitive user data are particularly vulnerable. The vulnerability also increases the risk of malware distribution through injected scripts, potentially leading to broader network compromise. Since the flaw is DOM-based, it can be triggered by user interaction with malicious links or content, making it a potent vector for phishing and social engineering attacks. The lack of authentication requirements and the ease of exploitation amplify the threat, potentially affecting a large number of end users and visitors to compromised sites. Organizations may face reputational damage and operational disruptions if exploited at scale.

To mitigate CVE-2024-50543, organizations should prioritize updating the 'amazing neo icon font for elementor' plugin to a patched version once it becomes available from the vendor. Until an official patch is released, administrators should consider disabling or removing the plugin if feasible. Implement strict input validation and output encoding on all user-supplied data that the plugin processes, particularly data inserted into the DOM. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. Web Application Firewalls (WAFs) can be configured to detect and block suspicious payloads targeting this vulnerability. Educate users about the risks of clicking unknown or suspicious links to reduce the likelihood of successful social engineering exploitation. Regularly audit and monitor web application logs for unusual activity indicative of exploitation attempts. Additionally, developers maintaining custom Elementor integrations should review their code for similar input handling issues and apply secure coding practices to prevent analogous vulnerabilities.
