EUVD-2025-20795

Comprehensive Technical Analysis of EUVD-2025-20795

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-20795 affects the Radiflow iSAP Smart Collector running on CentOS 7 with VSAP version 1.20. The vulnerability allows an unauthenticated user with management network access to retrieve and modify the device's configuration through exposed REST APIs on TCP ports 8084 and 8086. This can lead to unauthorized access to system settings, configuration modifications, and execution of commands such as system reboots.

Severity Evaluation:

• Base Score: 9.9 (Critical)
• Base Score Version: CVSS 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:H/A:L

The high base score indicates a critical vulnerability due to the ease of exploitation (low complexity, no authentication required) and the significant impact on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Network Access: An attacker needs access to the management network where the iSAP Smart Collector is deployed.
2. Unauthenticated REST APIs: The attacker can exploit the unauthenticated REST APIs exposed on TCP ports 8084 and 8086.

Exploitation Methods:

1. Information Gathering: The attacker can use the exposed APIs to retrieve system settings and configuration details.
2. Configuration Modification: The attacker can modify the device's configuration, potentially leading to unauthorized changes in operational settings.
3. Command Execution: The attacker can execute commands such as system reboots, which can disrupt the device's operation.

3. Affected Systems and Software Versions

Affected Systems:

• Radiflow iSAP Smart Collector

Software Versions:

• CentOS 7
• VSAP version 1.20

Note: The vulnerability affects versions 1.20 and potentially earlier versions up to 3.02-1.

4. Recommended Mitigation Strategies

1. Network Segmentation: Implement strict network segmentation to limit access to the management network.
2. Access Control: Enforce robust access control mechanisms to ensure only authorized users can access the management network.
3. API Authentication: Implement authentication for the REST APIs to prevent unauthorized access.
4. Patch Management: Apply the latest patches and updates provided by Radiflow to mitigate the vulnerability.
5. Monitoring and Logging: Implement comprehensive monitoring and logging to detect and respond to any unauthorized access attempts.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to European organizations using the Radiflow iSAP Smart Collector, particularly in critical infrastructure sectors such as energy, manufacturing, and transportation. Unauthorized access and modification of these devices can lead to operational disruptions, data breaches, and potential safety risks. The high severity of this vulnerability underscores the need for robust cybersecurity measures and continuous monitoring in industrial control systems (ICS) and operational technology (OT) environments.

6. Technical Details for Security Professionals

Technical Overview:

• Exposed Ports: TCP 8084 and 8086
• REST APIs: Unauthenticated APIs that allow access to system settings, configuration modification, and command execution.

Detection and Response:

1. Intrusion Detection Systems (IDS): Deploy IDS to monitor for unauthorized access attempts to the exposed ports.
2. Security Information and Event Management (SIEM): Integrate SIEM solutions to correlate and analyze logs for suspicious activities.
3. Incident Response Plan: Develop and implement an incident response plan tailored to ICS/OT environments to quickly address any detected vulnerabilities.
