Overview
A severe security vulnerability, identified as CVE-2025-63225, has been discovered in the Eurolab ELTS100_UBX device (firmware version ELTS100v1.UBX). This vulnerability stems from a broken access control implementation, allowing unauthenticated attackers to access and manipulate sensitive system functionalities.
Technical Details
The Eurolab ELTS100_UBX device suffers from a critical flaw: missing authentication on critical administrative endpoints. This absence of authentication allows remote attackers to bypass security measures and directly access sensitive system configurations. Specifically, attackers can:
- Modify system configurations
- Modify network configurations
- Upload malicious firmware updates
- Execute unauthorized actions
This vulnerability exists because the firmware does not require any form of authentication before allowing access to administrative functions. This allows for complete device compromise.
CVSS Analysis
Due to the severity and potential impact of this vulnerability, it is expected to receive a high CVSS score. However, the assigned CVSS score is currently listed as N/A. A full CVSS analysis will be provided once available. The lack of authentication for sensitive functions suggests a potential CVSS score of 9.0 or higher, indicating critical severity.
Possible Impact
The exploitation of CVE-2025-63225 can have devastating consequences:
- Full Device Compromise: Attackers gain complete control over the affected device.
- Data Breach: Sensitive data stored on or transmitted through the device can be compromised.
- Denial of Service: Attackers can disrupt the device’s operation, leading to a denial of service for legitimate users.
- Network Disruption: Compromised devices can be used as a launching pad for attacks against other devices on the network.
- Supply Chain Attacks: A compromised device can be used as an entry point to compromise other systems and devices in the supply chain.
Mitigation and Patch Steps
Currently, there is no official patch available from Eurolab. However, the following mitigation steps are recommended until a patch is released:
- Isolate the Device: If possible, isolate the ELTS100_UBX device from the network to prevent unauthorized access.
- Firewall Restrictions: Implement strict firewall rules to limit access to the device’s administrative interface. Only allow access from trusted IP addresses, if possible.
- Monitor Network Traffic: Monitor network traffic to and from the device for suspicious activity.
- Contact Eurolab: Contact Eurolab support (eurolab-srl.com) to inquire about a timeline for a security patch and to report your concerns.
- Consider Device Replacement: If the device is critical to your operations and a patch is not forthcoming, consider replacing the device with a more secure alternative.
