CVE-2024-50414 identifies a stored cross-site scripting (XSS) vulnerability in the Buttonizer Button contact VR plugin, which is used to add interactive contact buttons on websites. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be injected and stored persistently. When other users visit the affected pages, the malicious scripts execute in their browsers, potentially leading to session hijacking, theft of cookies or credentials, unauthorized actions on behalf of users, or redirection to malicious websites. This vulnerability affects all versions of the Button contact VR plugin up to and including 4.7.9.1. Exploitation does not require authentication, making it accessible to remote attackers who can submit crafted input. Although no known exploits have been reported in the wild, the risk remains significant due to the nature of stored XSS vulnerabilities. The lack of an official patch at the time of publication necessitates immediate attention from administrators. The vulnerability is particularly relevant for websites using the Buttonizer plugin, which is popular among WordPress users for enhancing user interaction. The absence of a CVSS score requires an assessment based on impact and exploitability factors, leading to a high severity rating. The vulnerability compromises the confidentiality and integrity of user data and can affect the availability of services if exploited for defacement or denial-of-service attacks.

The primary impact of CVE-2024-50414 is on the confidentiality and integrity of user data accessed through affected websites. Attackers can execute arbitrary JavaScript in the context of the victim's browser, enabling session hijacking, credential theft, and unauthorized actions. This can lead to compromised user accounts, data breaches, and loss of user trust. Additionally, attackers may deface websites or redirect users to malicious domains, damaging the organization's reputation and potentially causing financial losses. Since the vulnerability is stored XSS, the malicious payload persists and affects all users who visit the compromised page, increasing the attack surface. The ease of exploitation without authentication and the widespread use of the Buttonizer plugin in WordPress ecosystems amplify the risk. Organizations relying on this plugin for customer interaction or support are particularly vulnerable, as attackers can leverage the contact button functionality to inject malicious content. The lack of current known exploits provides a window for proactive mitigation, but the threat remains significant if left unaddressed.

Organizations should immediately audit their use of the Buttonizer Button contact VR plugin and identify affected versions (up to 4.7.9.1). Until an official patch is released, implement strict input validation and sanitization on all user-supplied data fields associated with the plugin to prevent malicious script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. Regularly monitor web application logs for suspicious input patterns or unusual activity related to the contact button feature. Consider temporarily disabling the Button contact VR plugin if mitigation controls cannot be effectively applied. Educate web administrators and developers on secure coding practices, especially regarding output encoding and input handling. Once the vendor releases a patch, prioritize its deployment across all affected systems. Additionally, conduct security testing and vulnerability scanning focused on XSS vectors in the affected web applications to ensure no residual vulnerabilities remain.
