CVE-2025-63225
📋 TL;DR
The Eurolab ELTS100_UBX device with firmware ELTS100v1.UBX has critical administrative endpoints that lack any authentication. Attackers can remotely access these endpoints to modify system configurations, upload malicious firmware, and execute unauthorized commands, leading to full device compromise. Organizations using this device in its vulnerable state are affected.
💻 Affected Systems
- Eurolab ELTS100_UBX device
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain complete control over the device, modify its functionality, disrupt operations, and potentially use it as a foothold for further network attacks.
Likely Case
Remote attackers exploit the vulnerability to reconfigure the device, upload malicious firmware, and disrupt its normal operation without detection.
If Mitigated
With proper network segmentation and access controls, the impact is limited to the device itself, preventing lateral movement.
🎯 Exploit Status
The vulnerability requires no authentication and has a public proof-of-concept available, making exploitation straightforward.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: http://eurolab-srl.com/
Restart Required: No
Instructions:
Check the vendor website for firmware updates or security advisories. If a patch is released, follow the vendor's instructions to update the firmware.
🔧 Temporary Workarounds
Network Segmentation
allIsolate the device from untrusted networks and restrict access to administrative interfaces.
Access Control Lists
allImplement firewall rules to block unauthorized access to the device's administrative endpoints.
🧯 If You Can't Patch
- Immediately isolate the device from the internet and untrusted networks.
- Monitor network traffic to the device for unauthorized access attempts and anomalous behavior.
🔍 How to Verify
Check if Vulnerable:
Attempt to access administrative endpoints (e.g., via HTTP requests to known URLs) without authentication; if accessible, the device is vulnerable.Check Version:
Check the device's web interface or console for firmware version information; it should display the version string.Verify Fix Applied:
After applying any vendor patch, verify that administrative endpoints now require authentication and reject unauthenticated requests.📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to administrative endpoints in device logs
- Unexpected configuration changes or firmware uploads
Network Indicators:
- Unusual HTTP requests to administrative URLs from untrusted sources
- Traffic patterns indicating configuration modifications
SIEM Query:
Example: 'source="device_logs" AND (url="*/admin*" OR action="upload_firmware") AND user="anonymous"'
