CVE-2024-13538 in BigBuy Dropshipping Connector for WooCommerce Plugin
Summary
by MITRE • 02/18/2025
The BigBuy Dropshipping Connector for WooCommerce plugin for WordPress is vulnerable to Full Path Disclosure in all versions up to, and including, 1.9.19. This is due the /vendor/cocur/slugify/bin/generate-default.php file being directly accessible and triggering an error. This makes it possible for unauthenticated attackers to retrieve the full path of the web application, which can be used to aid other attacks. The information displayed is not useful on its own, and requires another vulnerability to be present for damage to an affected website.

The vulnerability identified as CVE-2024-13538 affects the BigBuy Dropshipping Connector for WooCommerce plugin, a widely used integration tool for WordPress e-commerce platforms. This plugin facilitates dropshipping operations by connecting WooCommerce stores with BigBuy's inventory management system. The flaw exists in versions up to and including 1.9.19, representing a significant security gap that exposes the underlying system architecture to potential attackers. The vulnerability manifests through a direct file access issue that allows unauthenticated threat actors to obtain critical system information through a specific file path.
The technical implementation of this vulnerability stems from improper access controls within the plugin's directory structure. Specifically, the file /vendor/cocur/slugify/bin/generate-default.php remains directly accessible through web requests rather than being properly secured or excluded from public access. When this file is accessed, it triggers a PHP error that reveals the complete server path to the WordPress installation. This occurs because the file contains executable code that, when invoked without proper authentication or input validation, generates an error message containing the full filesystem path. The path disclosure vulnerability operates at the application level, making it particularly dangerous as it provides attackers with precise knowledge of the server environment structure.
The operational impact of this vulnerability extends beyond simple information disclosure, as it serves as a foundational element for more sophisticated attacks. While the path information alone may appear benign, it provides crucial intelligence for attackers planning subsequent exploitation attempts. The full path disclosure creates opportunities for attackers to craft more targeted attacks by understanding the exact file structure, directory permissions, and system layout. This information can be combined with other vulnerabilities to execute more effective exploitation strategies, such as local file inclusion attacks or directory traversal attempts. The vulnerability aligns with CWE-209, which specifically addresses information exposure through error messages, and represents a classic example of how seemingly minor access control issues can create significant security implications.
Security professionals should note that this vulnerability fits within the ATT&CK framework under the T1083 technique for "File and Directory Discovery," as it enables attackers to gather information about the target system's file structure. The lack of authentication requirements makes this particularly concerning for publicly accessible web applications. While the vulnerability does not directly compromise the system's integrity or confidentiality, it significantly reduces the attack surface by providing attackers with essential reconnaissance information. The impact is amplified when combined with other vulnerabilities, as the disclosed paths can be used to craft more precise attacks against the target environment.
Mitigation strategies for CVE-2024-13538 should focus on immediate access restriction and plugin updates. Administrators must ensure that the vulnerable file path /vendor/cocur/slugify/bin/generate-default.php is not accessible through web requests by implementing proper directory permissions or web server configuration restrictions. The most effective solution involves updating to the latest version of the BigBuy Dropshipping Connector plugin where this vulnerability has been patched. Organizations should also implement comprehensive web application firewalls to monitor and block access to sensitive vendor directories. Regular security audits of plugin installations and proper file permission management should be enforced to prevent similar issues from occurring in other components of the WordPress ecosystem. Additionally, implementing proper error handling mechanisms that prevent path information from being exposed in error messages aligns with industry best practices for secure application development and helps prevent similar vulnerabilities from arising in the future.
