CVE-2025-60964 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 multiple severe impacts including denial of service (DoS), privilege escalation, unauthorized disclosure of sensitive information, and potentially other unspecified consequences. The vulnerability arises from insufficient input validation or improper sanitization of user-supplied input in the device’s firmware, enabling attackers to manipulate command execution paths. Although no specific affected versions beyond 4.00 are listed, the vulnerability is tied to this firmware release. No CVSS score has been assigned yet, and there are no known exploits in the wild as of the publication date (October 6, 2025). The Sonoma D12 Network Time Server is used for precise time synchronization in network environments, often critical for infrastructure, telecommunications, and financial services. Successful exploitation could allow attackers to disrupt time synchronization services, which can cascade into broader operational failures or security control bypasses. The lack of authentication requirements or user interaction details is not specified, but given the nature of network time servers, remote exploitation is plausible. This vulnerability demands urgent attention due to the critical role of time servers in network operations and security.

The impact of CVE-2025-60964 on European organizations could be significant, especially those relying on EndRun Technologies Sonoma D12 Network Time Servers for critical infrastructure synchronization. Disruption or compromise of time synchronization can affect logging accuracy, security event correlation, and the operation of time-sensitive applications such as financial transactions, telecommunications, and industrial control systems. An attacker exploiting this vulnerability could cause denial of service, leading to operational downtime, or escalate privileges to gain deeper access within the network, potentially facilitating lateral movement or data exfiltration. The exposure of sensitive information could include configuration details or cryptographic keys used for securing communications. Given the centrality of time servers in maintaining network integrity and security, this vulnerability could undermine trust in security controls and compliance with regulatory requirements such as GDPR, which mandates data integrity and protection. The absence of known exploits currently provides a window for proactive mitigation, but the potential for rapid exploitation once public details are available is high.

1. Immediate action should include isolating the affected Sonoma D12 Network Time Servers from untrusted networks to reduce exposure. 2. Monitor network traffic for unusual command execution attempts or anomalies in time synchronization behavior. 3. Implement strict network segmentation and firewall rules to restrict access to the time server management interfaces to authorized personnel only. 4. Engage with EndRun Technologies for firmware updates or patches addressing this vulnerability; prioritize deployment as soon as they become available. 5. Employ intrusion detection and prevention systems (IDS/IPS) with signatures or heuristics capable of detecting command injection attempts targeting network time servers. 6. Conduct thorough audits of time server configurations and logs to identify any signs of compromise. 7. Consider deploying redundant time synchronization sources to maintain operational continuity during remediation. 8. Educate network and security teams about the risks associated with compromised time servers and the importance of timely patching and monitoring. 9. Review and enhance incident response plans to include scenarios involving time server compromise.
