The vulnerability identified as CVE-2023-39677 affects two popularprestashop modules namely MyPrestaModules Prestashop Module version 6.2.9 and UpdateProducts Prestashop Module version 3.6.9. This security flaw resides within the send.php file of these modules and represents a critical information disclosure vulnerability that can expose sensitive system details to unauthorized parties. The issue stems from the improper handling of phpinfo() function calls within the module's codebase, which inadvertently reveals comprehensive server configuration information including php settings, loaded extensions, system environment variables, and potentially database connection details. Such exposure creates significant security risks forprestashop merchants who rely on these modules for their online store operations.
The technical implementation of this vulnerability occurs through the send.php script which contains a direct call to the phpinfo() function without proper access controls or sanitization measures. When an attacker accesses this specific endpoint, the module executes the phpinfo() function and displays the complete php configuration information in the browser. This information disclosure represents a CWE-200 vulnerability category under the Common Weakness Enumeration framework, specifically addressing the exposure of sensitive information to unauthorized users. The flaw allows attackers to gather detailed insights about the server environment, which can be leveraged for subsequent exploitation attempts. According to ATT&CK framework, this vulnerability maps to T1592 - Obtain Capabilities and T1082 - System Information Discovery, as it provides adversaries with crucial reconnaissance data about the target system.
The operational impact of this vulnerability extends beyond simple information disclosure as it creates a gateway for more sophisticated attacks againstprestashop installations. Attackers can use the disclosed php configuration information to identify potential weaknesses in the server setup, including outdated php versions, insecure extensions, and misconfigured security settings. The exposure of database connection details, server paths, and php module configurations significantly increases the attack surface for the affected prestashop stores. This vulnerability particularly impacts e-commerce environments where sensitive customer data, payment information, and business-critical system configurations are stored. The risk is compounded because prestashop modules are widely used across the platform, meaning a single vulnerable module can affect numerous online stores simultaneously.
Mitigation strategies for CVE-2023-39677 require immediate action from affected merchants and system administrators. The primary recommendation involves updating both MyPrestaModules Prestashop Module to version 6.2.10 or higher and UpdateProducts Prestashop Module to version 3.7.0 or later, as these versions contain the necessary patches to address the phpinfo disclosure issue. Additionally, administrators should implement proper access controls to restrict direct access to module files and consider removing or disabling the send.php endpoint if it is not essential for operations. Security monitoring should be enhanced to detect unauthorized access attempts to phpinfo endpoints, and regular security audits should be conducted to identify similar vulnerabilities in other modules. Network-level protections including web application firewalls and access control lists should be configured to prevent exploitation attempts. The remediation process should also include comprehensive testing to ensure that the patched modules function correctly without introducing new security issues, as per industry best practices outlined in the OWASP Top Ten and NIST cybersecurity frameworks.
