CVE-2025-60959 is an operating system command injection vulnerability identified in the EndRun Technologies Sonoma D12 Network Time Server, specifically in firmware version 4.00 (F/W 6010-0071-000). This vulnerability allows an attacker to inject and execute arbitrary OS commands on the device, which can lead to unauthorized disclosure of sensitive information. The Sonoma D12 is a GPS-based network time server used to provide precise time synchronization across networks, which is critical for many applications including telecommunications, financial transactions, and industrial control systems. The vulnerability likely arises from insufficient input validation in the device’s management interface or command processing components, enabling attackers to manipulate commands passed to the underlying OS shell. Although no public exploits or CVSS score have been published yet, the nature of OS command injection typically allows attackers to gain significant control over the device. This can compromise the integrity and availability of time synchronization services, potentially causing cascading failures in dependent systems. The lack of available patches or detailed technical mitigations increases the urgency for organizations to implement interim protective measures. Given the device’s role in critical infrastructure, exploitation could have widespread operational and security implications.

For European organizations, the impact of this vulnerability can be substantial. The Sonoma D12 Network Time Server is often deployed in sectors requiring precise and reliable time synchronization, such as telecommunications networks, financial institutions for transaction timestamping, energy grids, and government infrastructure. Exploitation could lead to unauthorized access to sensitive configuration data or manipulation of time data, undermining system integrity and trustworthiness. Disruption of time synchronization can cause failures in logging, transaction processing, and network coordination, potentially leading to financial losses, regulatory non-compliance, and operational outages. Additionally, attackers gaining control over these devices could use them as pivot points for lateral movement within networks. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits following public disclosure. European organizations with critical infrastructure or high dependency on EndRun Technologies devices should consider this vulnerability a significant risk.

1. Inventory and identify all Sonoma D12 Network Time Servers running firmware version 4.00 within the network. 2. Restrict network access to the management interfaces of these devices using firewalls and network segmentation to limit exposure to trusted administrators only. 3. Implement strict authentication and authorization controls for device management, including the use of strong, unique credentials and multi-factor authentication if supported. 4. Monitor device logs and network traffic for unusual command execution patterns or unauthorized access attempts. 5. Engage with EndRun Technologies for official patches or firmware updates addressing this vulnerability and apply them promptly once available. 6. As an interim measure, consider isolating affected devices from critical network segments or replacing them with alternative time synchronization solutions if feasible. 7. Conduct regular security assessments and penetration testing focused on network time servers to detect potential exploitation attempts. 8. Educate network and security teams about the risks associated with time server vulnerabilities and the importance of timely patch management.
