CVE-2025-60963
📋 TL;DR
This CVE describes an OS command injection vulnerability in EndRun Technologies Sonoma D12 Network Time Server firmware that allows attackers to execute arbitrary commands on the device. Attackers can exploit this to run malicious code, disrupt time synchronization services, escalate privileges, or access sensitive information. Organizations using the affected firmware version are at risk.
💻 Affected Systems
- EndRun Technologies Sonoma D12 Network Time Server (GPS)
📦 What is this software?
Sonoma D12 Firmware by Endruntechnologies
⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise allowing attackers to execute arbitrary commands, install persistent backdoors, disrupt critical time synchronization services across the network, and potentially pivot to other systems.
Likely Case
Attackers gain unauthorized access to execute commands, potentially disrupting NTP services, extracting configuration data, or using the device as a foothold for further network attacks.
If Mitigated
Limited impact with proper network segmentation, restricted administrative access, and monitoring in place, though the vulnerability remains present.
🎯 Exploit Status
OS command injection vulnerabilities typically have low exploitation complexity when unauthenticated access is possible.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: http://endrun.com
Restart Required: Yes
Instructions:
1. Check vendor website for firmware updates. 2. Download latest firmware. 3. Follow vendor's firmware update procedure. 4. Verify successful update and restart device.
🔧 Temporary Workarounds
Network Segmentation
allIsolate the Sonoma D12 device from untrusted networks and restrict access to management interfaces.
Access Control Lists
allImplement strict firewall rules to limit which IP addresses can communicate with the device's management interfaces.
🧯 If You Can't Patch
- Segment the device on a dedicated VLAN with strict access controls
- Implement network monitoring for unusual traffic patterns to/from the device
🔍 How to Verify
Check if Vulnerable:
Check device firmware version via web interface or CLI. If version is 4.00 (6010-0071-000), device is vulnerable.Check Version:
Check via web interface at device IP or consult device documentation for CLI version command.Verify Fix Applied:
After updating, verify firmware version is no longer 4.00 and test management interfaces for command injection vulnerabilities.📡 Detection & Monitoring
Log Indicators:
- Unusual command execution in system logs
- Failed authentication attempts to management interfaces
- Unexpected process creation
Network Indicators:
- Unusual outbound connections from NTP server
- Suspicious traffic to management ports
- Anomalous payloads in HTTP requests to device
SIEM Query:
Example: 'source_ip=[NTP_SERVER_IP] AND (destination_port=80 OR destination_port=443) AND http_method=POST AND url_contains="command" OR url_contains="exec"'
