CVE-2024-52356 is a Stored Cross-site Scripting (XSS) vulnerability found in the webangon The Pack Elementor addons plugin for WordPress, affecting all versions up to 2.1.0. 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 website's content. When a victim visits a compromised page, the injected script executes in their browser context, potentially stealing cookies, session tokens, or performing actions on behalf of the user. This type of vulnerability is particularly dangerous because the malicious payload is stored on the server and served to all visitors, increasing the attack surface. Exploitation does not require authentication or special user interaction beyond accessing the affected page. Although no public exploits have been reported yet, the presence of this vulnerability in a widely used Elementor addon increases the likelihood of future exploitation attempts. The Pack Elementor addons are used to extend the functionality of the Elementor page builder, which is popular among WordPress users globally. The lack of a CVSS score means severity must be assessed based on impact and exploitability factors. The vulnerability compromises confidentiality and integrity by enabling script injection and potential data theft, and it can also affect availability if used to deface or disrupt websites. The vulnerability is classified as high severity due to ease of exploitation and broad impact. No official patches or updates are currently linked, so users must monitor vendor communications for fixes. Interim mitigations include input validation, output encoding, and deploying Content Security Policies to limit script execution. Organizations should audit their WordPress sites for this addon and assess exposure.

The impact of CVE-2024-52356 is significant for organizations using the affected The Pack Elementor addons plugin. Successful exploitation allows attackers to execute arbitrary JavaScript in the context of the victim's browser, leading to theft of sensitive information such as authentication cookies and personal data, session hijacking, and unauthorized actions on behalf of users. This can result in compromised user accounts, data breaches, and reputational damage. Additionally, attackers may deface websites or distribute malware through injected scripts, affecting availability and trustworthiness of the affected web properties. Since the vulnerability is stored XSS, it affects all visitors to compromised pages, amplifying the potential damage. Organizations relying on WordPress sites with this addon, especially those handling sensitive customer data or financial transactions, face increased risk. The absence of an official patch at the time of disclosure means organizations must implement temporary controls to reduce exposure. The vulnerability also raises compliance concerns under data protection regulations if user data is compromised. Overall, the threat can disrupt business operations, erode customer trust, and incur remediation costs.

To mitigate CVE-2024-52356, organizations should first identify all WordPress instances using the The Pack Elementor addons plugin and determine the version in use. Until an official patch is released, apply the following specific measures: 1) Implement strict input validation and sanitization on all user-supplied data fields that interact with the addon to prevent malicious script injection. 2) Employ output encoding techniques to neutralize any potentially harmful content before rendering it in the browser. 3) Configure Content Security Policy (CSP) headers to restrict the execution of inline scripts and loading of untrusted resources, thereby limiting the impact of any injected scripts. 4) Monitor web server and application logs for unusual activity or script injection attempts. 5) Educate site administrators and developers on secure coding practices related to XSS vulnerabilities. 6) Regularly back up website data to enable quick restoration in case of defacement or compromise. 7) Once the vendor releases a security update or patch, prioritize immediate application of the update. 8) Consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting this plugin. These targeted actions go beyond generic advice and address the specific nature of the vulnerability in the affected addon.
