CVE-2025-54160 is a path traversal vulnerability identified in Synology BeeDrive for desktop versions prior to 1.4.2-13960. The vulnerability stems from improper validation and limitation of pathnames, allowing local users to escape restricted directories. This flaw enables attackers to access files and directories outside the intended sandbox, potentially leading to arbitrary code execution. The attack vector requires local access with low privileges and does not require user interaction, increasing the risk in environments where multiple users share systems or where local access can be gained through other means. The vulnerability affects all versions before the fixed release, indicating a broad scope. The CVSS 3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability due to the ability to execute arbitrary code. Although no public exploits are currently known, the vulnerability's nature suggests it could be leveraged for local privilege escalation or lateral movement within networks. The lack of patch links in the provided data suggests organizations should monitor Synology's official channels for updates. This vulnerability is particularly concerning for enterprise environments where BeeDrive is used for file synchronization and backup, as exploitation could compromise sensitive data and disrupt operations.

For European organizations, this vulnerability poses a significant risk, especially in sectors relying on Synology BeeDrive for desktop for file storage and synchronization. Successful exploitation could lead to unauthorized access to sensitive files, data corruption, or full system compromise through arbitrary code execution. This could disrupt business continuity, lead to data breaches, and cause compliance violations under regulations like GDPR. Organizations with multi-user systems or those that allow local user access are particularly vulnerable. The ability to execute code without user interaction and with low privileges increases the threat of insider attacks or attacks following initial local compromise. Critical infrastructure, government agencies, and enterprises using Synology products are at heightened risk, potentially impacting national security and economic stability in affected countries.

Organizations should immediately verify the version of Synology BeeDrive for desktop in use and upgrade to version 1.4.2-13960 or later once available. Until patches are applied, restrict local user access to trusted personnel only and implement strict access controls on systems running BeeDrive. Employ application whitelisting to prevent unauthorized code execution and monitor file system activities for unusual access patterns indicative of path traversal attempts. Regularly audit user privileges and remove unnecessary local accounts. Network segmentation can limit the spread of compromise if exploitation occurs. Additionally, maintain up-to-date backups and ensure endpoint protection solutions are configured to detect suspicious local activities. Organizations should also stay informed through Synology security advisories for any new developments or exploit disclosures.
