CVE-2024-8164 is a vulnerability identified in the BeikeShop e-commerce platform developed by Chengdu Everbrite Network Technology, affecting versions 1.5.0 through 1.5.5. The root cause lies in the improper validation and sanitization of the 'new_name' parameter in the rename function located in /Admin/Http/Controllers/FileManagerController.php. This flaw allows an attacker to manipulate the argument to perform unrestricted file uploads remotely without requiring user interaction or elevated privileges beyond low-level access. Such unrestricted upload capability can enable attackers to upload malicious files, including web shells or scripts, which may lead to remote code execution, data breaches, or service disruption. The vulnerability has a CVSS 4.0 base score of 5.3, indicating a medium severity level due to the ease of exploitation (network attack vector, low complexity, no user interaction) but limited scope and impact. Although no known exploits are currently active in the wild, the public disclosure increases the risk of exploitation attempts. The recommended remediation is to upgrade BeikeShop to version 1.6.0, where the vulnerability has been addressed by proper input validation and access controls on file operations. Organizations should also audit their file upload and management functionalities for similar weaknesses and monitor for suspicious file activity.

For European organizations, this vulnerability poses a significant risk to e-commerce platforms running BeikeShop, potentially leading to unauthorized file uploads that can compromise system integrity and confidentiality. Attackers could deploy web shells or malware, enabling persistent access, data theft, or disruption of online retail services. This can result in financial losses, reputational damage, and regulatory penalties under GDPR if customer data is exposed. The medium CVSS score reflects moderate impact, but the ease of remote exploitation without user interaction increases urgency. Organizations in sectors reliant on online commerce, such as retail and logistics, are particularly vulnerable. Additionally, supply chain risks arise if third-party vendors use affected BeikeShop versions. The vulnerability could also be leveraged as a foothold for lateral movement within corporate networks, amplifying its impact.

1. Immediately upgrade all BeikeShop installations to version 1.6.0 or later to apply the official patch addressing this vulnerability. 2. Implement strict input validation and sanitization on all file management functions, especially those handling file names and uploads. 3. Restrict file upload permissions to authenticated and authorized users only, and enforce the principle of least privilege. 4. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious file upload attempts targeting the vulnerable endpoint. 5. Monitor server logs and file system changes for unusual activity indicative of exploitation attempts, such as unexpected file creations or renames. 6. Conduct regular security assessments and code reviews focusing on file handling components. 7. Isolate e-commerce platforms from critical internal networks to limit lateral movement in case of compromise. 8. Educate development and operations teams about secure file handling practices and the risks of unrestricted uploads.
