CVE-2025-64265 identifies a missing authorization vulnerability in the N-Media Frontend File Manager, specifically within the nmedia-user-file-uploader component. This vulnerability arises from incorrectly configured access control security levels, allowing unauthorized users to interact with the file upload functionality without proper permission checks. The affected product versions include all releases up to and including version 23.2. The vulnerability is classified with a CVSS 3.1 base score of 4.3 (medium severity), reflecting a network attack vector, low attack complexity, no privileges required, but requiring user interaction. The impact primarily concerns confidentiality, as unauthorized users might gain access to files or upload malicious content, but it does not affect integrity or availability directly. No known exploits have been reported in the wild, and no official patches have been published yet. The vulnerability was reserved on October 29, 2025, and published on November 13, 2025. The lack of authorization checks suggests a design or configuration flaw in the frontend file manager's access control mechanisms, which could be exploited by attackers to bypass security restrictions and perform unauthorized file operations. This vulnerability is particularly relevant for organizations relying on N-Media's frontend file management solutions for handling user-uploaded content or managing files accessible via web interfaces.

For European organizations, the primary impact of CVE-2025-64265 is the potential unauthorized access to or upload of files through the N-Media Frontend File Manager. This could lead to exposure of sensitive information if confidential files are accessible or uploaded maliciously. While the vulnerability does not directly compromise system integrity or availability, unauthorized file uploads could serve as a vector for further attacks, such as hosting malicious scripts or malware. Organizations in sectors with strict data protection regulations (e.g., GDPR) may face compliance risks if sensitive data is exposed. The requirement for user interaction reduces the risk somewhat but does not eliminate it, especially in environments with many users or where social engineering could be employed. The absence of known exploits in the wild suggests limited immediate threat, but the vulnerability should be addressed proactively to prevent future exploitation. The impact is more pronounced for organizations that expose the frontend file manager to the internet or have weak internal network segmentation.

1. Immediately review and restrict access to the N-Media Frontend File Manager, ensuring only authorized users can reach the file uploader interface. 2. Implement strict access control policies at both application and network levels, including IP whitelisting and authentication enforcement. 3. Monitor file upload activities for unusual patterns, such as unexpected file types or upload volumes, using logging and anomaly detection tools. 4. Disable or limit the file upload functionality if not essential, or replace it with a more secure alternative. 5. Apply the principle of least privilege to all users interacting with the file manager. 6. Segregate the frontend file manager environment from critical systems to contain potential breaches. 7. Stay alert for official patches or updates from N-Media and apply them promptly once available. 8. Conduct security awareness training to reduce the risk of user interaction-based exploitation. 9. Perform regular security assessments and penetration tests focusing on access control mechanisms in the file management system.
