CVE-2024-8165 is a path traversal vulnerability identified in the BeikeShop e-commerce platform developed by Chengdu Everbrite Network Technology, affecting versions 1.5.0 through 1.5.5. The vulnerability resides in the exportZip function within the /admin/file_manager/export endpoint, where insufficient validation of the 'path' parameter allows an attacker to traverse directories and access files outside the intended directory scope. This can lead to unauthorized disclosure of sensitive files on the server. The vulnerability can be exploited remotely over the network without requiring authentication or user interaction, making it relatively easy to exploit. The CVSS 4.0 score is 5.3 (medium), reflecting the low complexity of the attack vector (network), no privileges required, and no user interaction needed, but limited impact on confidentiality and no impact on integrity or availability. Although no known exploits are currently observed in the wild, a public exploit is available, increasing the risk of exploitation. The recommended mitigation is to upgrade to BeikeShop version 1.6.0, where the vulnerability has been fixed by proper input validation and sanitization of the path parameter. Organizations should also review access controls and monitor for suspicious file access patterns to detect exploitation attempts.

For European organizations, exploitation of this vulnerability could lead to unauthorized disclosure of sensitive files stored on BeikeShop servers, potentially exposing customer data, configuration files, or internal documents. While the vulnerability does not allow modification or deletion of files, the confidentiality breach could facilitate further attacks such as credential theft or lateral movement. E-commerce platforms using BeikeShop may face reputational damage and regulatory scrutiny under GDPR if personal data is exposed. The ease of remote exploitation without authentication increases the risk, especially for organizations with externally accessible BeikeShop admin interfaces. However, the absence of known active exploitation in the wild somewhat reduces immediate risk. Still, the availability of a public exploit means attackers could quickly weaponize this vulnerability. Organizations should consider this a moderate threat that requires timely remediation to avoid potential data breaches and compliance violations.

1. Upgrade BeikeShop installations to version 1.6.0 or later immediately to apply the official patch addressing the path traversal vulnerability. 2. Restrict network access to the /admin/file_manager/export endpoint using firewalls or web application firewalls (WAFs) to limit exposure to trusted IP addresses only. 3. Implement strict input validation and sanitization on all user-supplied parameters, especially those related to file paths, to prevent traversal sequences such as '../'. 4. Conduct regular security audits and penetration testing focused on file management functionalities to detect similar vulnerabilities. 5. Monitor server logs for unusual file access patterns or attempts to access sensitive files outside expected directories. 6. Employ least privilege principles for the web application and underlying file system permissions to minimize the impact of any successful exploitation. 7. Educate system administrators and developers about secure coding practices related to file handling and path validation. 8. Consider deploying runtime application self-protection (RASP) tools that can detect and block path traversal attempts in real time.
