CVE-2024-52484 is a reflected Cross-site Scripting (XSS) vulnerability found in the deepintowp Wc Recently viewed products WordPress plugin, affecting versions up to 1.0.1. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows attackers to inject malicious JavaScript code into web pages viewed by other users. When a victim visits a specially crafted URL or page containing the malicious payload, the injected script executes in their browser context. This can lead to session hijacking, theft of sensitive information, unauthorized actions performed on behalf of the user, or delivery of further malware. The plugin is designed to display recently viewed products on e-commerce WordPress sites, meaning that online stores using this plugin are the primary targets. Currently, there are no known exploits in the wild, and no official patch or CVSS score has been published. The vulnerability requires no authentication but does require user interaction (visiting a malicious link). The lack of input sanitization or output encoding in the plugin's code is the root cause. This vulnerability highlights the importance of secure coding practices in WordPress plugins, especially those handling dynamic content generation based on user input.

The impact of CVE-2024-52484 can be significant for organizations running WordPress e-commerce sites using the affected plugin. Successful exploitation allows attackers to execute arbitrary scripts in the context of users' browsers, potentially leading to session hijacking, theft of personal and payment information, unauthorized transactions, and distribution of malware. This can damage customer trust, result in financial losses, and lead to regulatory compliance issues related to data protection. Since the vulnerability is reflected XSS, it requires tricking users into clicking malicious links, which can be facilitated through phishing campaigns. The scope of affected systems is limited to sites using the vulnerable plugin, but given WordPress's large market share in e-commerce, the potential reach is broad. The vulnerability affects confidentiality and integrity primarily, with availability impact being minimal unless combined with other attacks. Organizations with high volumes of online transactions and sensitive customer data are at greater risk.

To mitigate CVE-2024-52484, organizations should first monitor for an official patch from the plugin vendor and apply it immediately upon release. Until a patch is available, administrators can implement manual input validation and output encoding in the plugin's code to neutralize malicious input. Employing a Web Application Firewall (WAF) with rules to detect and block reflected XSS payloads targeting the plugin's endpoints can provide interim protection. Educating users and staff about phishing risks can reduce the likelihood of successful exploitation. Additionally, implementing Content Security Policy (CSP) headers can help restrict the execution of unauthorized scripts in browsers. Regular security audits of WordPress plugins and minimizing the use of unnecessary or untrusted plugins can reduce exposure. Monitoring web logs for suspicious query parameters or unusual traffic patterns related to the plugin can aid in early detection of exploitation attempts.
