CVE-2025-4868 is a path traversal vulnerability identified in the merikbest ecommerce-spring-reactjs product, specifically affecting an unknown functionality within the /api/v1/admin/ File Upload Endpoint. The vulnerability arises from improper validation or sanitization of the 'filename' argument, allowing an attacker to manipulate this parameter to traverse directories outside the intended file upload directory. This can enable unauthorized access to sensitive files on the server's filesystem. The vulnerability can be exploited remotely without requiring user interaction or authentication, increasing its risk profile. The product uses continuous delivery with rolling releases, which complicates precise version tracking and patch availability. The CVSS 4.0 score is 5.3 (medium severity), reflecting network attack vector, low attack complexity, no privileges or user interaction required, but limited confidentiality, integrity, and availability impact. No known exploits are currently reported in the wild, but public disclosure of the exploit code exists, increasing the likelihood of exploitation attempts. The vulnerability affects the backend component handling file uploads in an ecommerce platform built with Spring and ReactJS, which is likely used by online retail businesses. The path traversal can lead to exposure or modification of critical files, potentially compromising the server or application integrity.

For European organizations using the merikbest ecommerce-spring-reactjs platform, this vulnerability poses a risk of unauthorized access to server files, which can lead to data breaches, leakage of sensitive business or customer information, and potential disruption of ecommerce services. Attackers exploiting this flaw could access configuration files, credentials, or other sensitive data, facilitating further attacks such as privilege escalation or persistent compromise. Given the ecommerce context, this could also impact customer trust and regulatory compliance, especially under GDPR requirements. The medium severity score suggests the impact is significant but not catastrophic; however, the ease of remote exploitation without authentication increases urgency. Organizations relying on this platform should consider the potential for reputational damage and operational disruption if exploited.

To mitigate this vulnerability, organizations should implement strict validation and sanitization of all file upload parameters, especially the 'filename' argument, to prevent directory traversal sequences (e.g., '../'). Employ allowlisting of acceptable file names and extensions, and enforce storage of uploaded files in isolated directories with restricted permissions. Use secure coding practices to avoid direct filesystem path concatenation with user input. Additionally, monitor and restrict access to the /api/v1/admin/ endpoint, ideally limiting it to trusted administrators and internal networks. Implement Web Application Firewalls (WAFs) with rules to detect and block path traversal attempts. Since no official patches are currently available due to continuous delivery practices, organizations should engage with the vendor for updates or consider temporary compensating controls such as disabling the vulnerable endpoint if feasible. Regularly audit logs for suspicious file access patterns and maintain up-to-date backups to recover from potential compromises.
