CVE-2025-60957
📋 TL;DR
This OS command injection vulnerability in EndRun Technologies Sonoma D12 Network Time Server allows attackers to execute arbitrary operating system commands on the device. Attackers can gain full control of the time server, potentially disrupting time synchronization services across networks. Organizations using this specific firmware version are affected.
💻 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 compromise of the time server allowing attackers to execute arbitrary code, pivot to other network devices, disrupt time-sensitive operations, and potentially cause cascading failures in dependent systems.
Likely Case
Attackers gain unauthorized access to the time server, modify time settings to disrupt network operations, and potentially use the device as a foothold for further network attacks.
If Mitigated
Limited impact with proper network segmentation and access controls preventing exploitation attempts from reaching the vulnerable interface.
🎯 Exploit Status
OS command injection vulnerabilities typically have low exploitation complexity when unauthenticated access is available. The advisory suggests multiple attack vectors including arbitrary code execution.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: http://endrun.com
Restart Required: Yes
Instructions:
1. Check EndRun Technologies website for security advisories
2. Download updated firmware if available
3. Backup current configuration
4. Upload and apply new firmware
5. Verify functionality after update
🔧 Temporary Workarounds
Network Segmentation
allIsolate the Sonoma D12 time server from untrusted networks and restrict access to management interfaces
Access Control Lists
linuxImplement strict firewall rules to only allow NTP traffic (UDP 123) and block all other management ports
iptables -A INPUT -p udp --dport 123 -j ACCEPT
iptables -A INPUT -j DROP
🧯 If You Can't Patch
- Segment the device on a dedicated VLAN with strict access controls
- Monitor network traffic to/from the device for unusual patterns or exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check the firmware version via the web interface or serial console. If version is 6010-0071-000 Ver 4.00, the device is vulnerable.Check Version:
Check via web interface at device IP or use serial console connectionVerify Fix Applied:
Verify firmware version has been updated to a version later than 6010-0071-000 Ver 4.00📡 Detection & Monitoring
Log Indicators:
- Unusual command execution in system logs
- Failed authentication attempts to management interface
- Unexpected process creation
Network Indicators:
- Unusual traffic patterns to management ports
- Exploit attempts containing shell metacharacters in HTTP requests
- Outbound connections from the time server to unexpected destinations
