CVE-2025-3497 identifies a significant security vulnerability in the Radiflow iSAP Smart Collector product, specifically version 1.20. The root cause of this vulnerability is the use of an unmaintained third-party component: the underlying Linux distribution, CentOS 7 - VSAP 1.20, which reached its end of life (EOL) on June 30, 2024. Once a Linux distribution reaches EOL, it no longer receives security patches or updates, leaving any newly discovered or existing vulnerabilities unmitigated. This creates an exploitable attack surface within the Radiflow iSAP Smart Collector device. The CVSS v3.1 score of 8.7 (high severity) reflects the critical nature of this vulnerability. The vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:H/A:H indicates that the vulnerability can be exploited remotely over the network (AV:N) with low attack complexity (AC:L), but requires high privileges (PR:H) and no user interaction (UI:N). The scope is changed (S:C), meaning the exploit affects resources beyond the initially vulnerable component. The impact is high on integrity and availability (I:H/A:H) but no direct confidentiality impact (C:N). This suggests that an attacker with high privileges on the device could leverage unpatched vulnerabilities in the obsolete CentOS 7 base to compromise system integrity and availability, potentially disrupting operations or injecting malicious code. No patches are currently available, and no known exploits in the wild have been reported yet. The vulnerability is categorized under CWE-1104, which concerns the use of unmaintained third-party components, emphasizing the risk of relying on outdated software dependencies. Given the critical role of Radiflow iSAP Smart Collector in industrial and infrastructure environments, this vulnerability poses a significant risk if left unaddressed.

For European organizations, the impact of this vulnerability could be substantial, especially those operating critical infrastructure, industrial control systems, or utilities that rely on Radiflow iSAP Smart Collector devices. Exploitation could lead to unauthorized modification or disruption of data integrity and system availability, potentially causing operational downtime, safety risks, or cascading failures in industrial processes. The lack of confidentiality impact reduces the risk of data leakage but does not mitigate the threat to operational continuity. Since the vulnerability requires high privileges, initial access controls are a mitigating factor; however, if an attacker gains privileged access (e.g., via lateral movement or insider threat), they could exploit this vulnerability to escalate control or cause denial of service. The changed scope indicates that the impact could extend beyond the device itself, potentially affecting connected systems or networks. European organizations in sectors such as energy, manufacturing, transportation, and critical infrastructure are particularly at risk due to the strategic importance of these sectors and their reliance on industrial IoT and SCADA devices. The absence of patches and the EOL status of the underlying OS complicate remediation and increase exposure time.

1. Immediate Inventory and Assessment: European organizations should identify all Radiflow iSAP Smart Collector devices running version 1.20 or earlier and assess their exposure and network segmentation. 2. Network Segmentation and Access Controls: Restrict network access to these devices to trusted management networks only, employing strict firewall rules and VPNs to limit exposure. 3. Privilege Management: Enforce the principle of least privilege for users and processes interacting with these devices to reduce the risk of privilege escalation. 4. Monitoring and Anomaly Detection: Implement enhanced monitoring for unusual activity or signs of compromise on these devices, including integrity checks and network traffic analysis. 5. Vendor Engagement: Engage with Radiflow for updates or patches addressing this vulnerability or for guidance on secure configurations or migration paths. 6. OS Upgrade or Replacement: Plan for migration away from the obsolete CentOS 7 base to a supported and actively maintained OS version or device firmware, if possible. 7. Incident Response Preparedness: Prepare incident response plans specific to potential exploitation scenarios involving these devices. 8. Compensating Controls: Use application-layer protections, such as intrusion prevention systems (IPS) and endpoint detection and response (EDR) solutions, to detect and block exploitation attempts. These steps go beyond generic advice by focusing on immediate containment, privilege restriction, and proactive monitoring tailored to the specific product and its environment.
