CVE-2024-13622 in File Uploads Addon for WooCommerce Plugin
Summary
by MITRE • 02/18/2025
The File Uploads Addon for WooCommerce plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.7.1 via the 'uploads' directory. This makes it possible for unauthenticated attackers to extract sensitive data stored insecurely in the /wp-content/uploads directory which can contain file attachments uploaded by customers.

The File Uploads Addon for WooCommerce plugin presents a critical security vulnerability classified as sensitive information exposure affecting versions up to and including 1.7.1. This vulnerability stems from improper access controls within the plugin's implementation, specifically targeting the WordPress uploads directory structure. The flaw allows unauthenticated attackers to directly access files stored in the /wp-content/uploads directory without proper authentication or authorization mechanisms. The vulnerability represents a direct violation of the principle of least privilege and demonstrates inadequate input validation and access control measures within the plugin's file handling routines. Security researchers have identified this issue as a significant risk to e-commerce platforms utilizing WooCommerce, as the uploads directory typically contains sensitive customer data including order documents, invoices, and other confidential attachments.
The technical exploitation of this vulnerability occurs through direct path traversal attacks against the plugin's file access endpoints. Attackers can construct malicious URLs that bypass the plugin's intended access controls and directly retrieve files from the WordPress uploads directory. This exposure affects the underlying WordPress file system structure and demonstrates a failure in implementing proper access control lists or authentication checks before serving file content. The vulnerability is particularly concerning because it affects the core WordPress upload directory which is commonly used by various plugins and themes to store user-generated content, customer data, and administrative attachments. This type of vulnerability aligns with CWE-200, which describes improper exposure of sensitive information, and represents a failure in the secure coding practices typically expected in web application development. The attack surface is expanded by the fact that many WooCommerce installations rely heavily on file uploads for customer communication and order processing, making the exposed data particularly valuable to threat actors.
The operational impact of this vulnerability extends beyond simple data exposure, as it creates potential for significant data breaches and compliance violations. Customer attachments stored in the uploads directory may contain personal information, financial details, or proprietary business data that could be exploited for identity theft, fraud, or competitive advantage. The unauthenticated nature of the attack means that threat actors can exploit this vulnerability without requiring any credentials, making detection and prevention particularly challenging for system administrators. Organizations using affected versions of the plugin face potential regulatory penalties under data protection frameworks such as gdpr and pci dss, as the exposure of customer data violates fundamental privacy and security requirements. The vulnerability also impacts the overall security posture of WordPress installations by demonstrating poor access control implementation that could serve as a foothold for more sophisticated attacks. This exposure creates opportunities for attackers to gather intelligence about the target environment and potentially escalate privileges through additional exploitation vectors.
Mitigation strategies for this vulnerability require immediate action to address the root cause through plugin updates and access control hardening. Organizations should upgrade to the latest version of the File Uploads Addon for WooCommerce plugin where the vulnerability has been patched, as this represents the most direct solution to the issue. System administrators should implement additional access controls by restricting direct access to the uploads directory through web server configuration changes, ensuring that only authorized users can access the file system. The implementation of proper authentication mechanisms for file access endpoints should be enforced, potentially through the use of token-based access controls or session management. Network-level protections such as web application firewalls should be deployed to monitor and block suspicious file access patterns that could indicate exploitation attempts. Regular security audits of WordPress installations should be conducted to identify similar access control vulnerabilities in other plugins or themes, as this vulnerability demonstrates a common pattern of insecure file handling practices. The remediation process should also include the implementation of automated monitoring for unauthorized access attempts and the establishment of incident response procedures to address potential data exposure events. Organizations should consider implementing data loss prevention measures to protect sensitive information stored in upload directories and ensure compliance with industry security standards such as those defined in the NIST cybersecurity framework and ISO 27001 requirements.
