CVE-2024-49225 is a stored cross-site scripting (XSS) vulnerability identified in the swebdeveloper wpPricing Builder WordPress plugin, specifically 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 attackers to inject malicious JavaScript code that is stored persistently within the plugin's data structures. When an unsuspecting user visits a page containing the injected script, the malicious code executes in their browser context. This can lead to session hijacking, unauthorized actions performed with the victim's privileges, defacement, or distribution of malware. The vulnerability does not require authentication, meaning any unauthenticated attacker can exploit it by submitting crafted input to the plugin. No user interaction beyond visiting the affected page is necessary to trigger the payload. The absence of a CVSS score suggests this is a newly disclosed issue, with no known public exploits at the time of publication. However, stored XSS vulnerabilities in WordPress plugins are frequently targeted due to the widespread use of WordPress and the potential for significant impact on website visitors and administrators. The plugin wpPricing Builder is used to create responsive pricing tables, commonly employed in business and e-commerce websites, increasing the attractiveness of this vulnerability to attackers. The vulnerability was published on October 18, 2024, and assigned by Patchstack, but no official patches or mitigations are linked yet, emphasizing the need for immediate attention by site administrators.

The impact of CVE-2024-49225 is substantial for organizations using the wpPricing Builder plugin. Successful exploitation can compromise the confidentiality and integrity of user sessions by enabling attackers to steal cookies or tokens, potentially leading to account takeover. Attackers may also perform unauthorized actions on behalf of users, including administrators, resulting in website defacement, data manipulation, or further malware distribution. The availability of the site could be indirectly affected if attackers use the vulnerability to inject disruptive scripts or launch further attacks. Given the stored nature of the XSS, the malicious payload persists and can affect multiple users over time, increasing the scope of impact. Organizations relying on this plugin for pricing display on their websites, especially those handling sensitive customer data or financial transactions, face elevated risks. The lack of authentication requirements and ease of exploitation make this vulnerability attractive for automated attacks and mass exploitation campaigns once public exploit code becomes available. This could lead to reputational damage, loss of customer trust, and potential regulatory consequences for affected organizations.

To mitigate CVE-2024-49225, organizations should first check for and apply any official patches or updates released by the wpPricing Builder plugin developers as soon as they become available. In the absence of patches, administrators should consider temporarily disabling the plugin or removing it if it is not essential. Implementing a Web Application Firewall (WAF) with rules to detect and block common XSS payloads can provide interim protection. Site owners should also audit and sanitize all user inputs related to the plugin manually, ensuring that any data stored or displayed is properly escaped and validated. Employing Content Security Policy (CSP) headers can help reduce the impact of injected scripts by restricting script execution sources. Regularly scanning the website for malicious scripts and monitoring logs for suspicious activity can aid in early detection of exploitation attempts. Educating site administrators about the risks and signs of XSS attacks will improve response readiness. Finally, consider isolating or sandboxing the plugin's output areas to limit the potential damage of any injected scripts.
