CVE-2025-13373 identifies a critical SQL Injection vulnerability in Advantech iView, a product commonly used for industrial monitoring and management. The vulnerability exists because the software does not properly sanitize SNMP v1 trap requests received on UDP port 162. SNMP traps are unsolicited messages sent by network devices to notify management systems of events. In this case, maliciously crafted SNMP trap payloads can include SQL commands that the iView backend database executes without proper validation, leading to SQL Injection (CWE-89). This allows an unauthenticated attacker to remotely execute arbitrary SQL queries, potentially extracting sensitive data, modifying or deleting records, or causing denial of service by corrupting the database. The vulnerability is remotely exploitable over the network without any authentication or user interaction, increasing its risk profile. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality. No patches have been linked yet, and no exploits are publicly known, but the vulnerability is published and should be considered exploitable. Advantech iView is often deployed in industrial control systems (ICS) and critical infrastructure environments, where database integrity and availability are paramount. The improper input validation on SNMP traps represents a significant attack surface, especially since SNMP traffic is often allowed through firewalls for monitoring purposes. This vulnerability highlights the importance of rigorous input validation on all network-facing services, especially those handling management protocols like SNMP.

For European organizations, especially those in industrial sectors such as manufacturing, energy, transportation, and utilities, this vulnerability poses a severe risk. Exploitation could lead to unauthorized disclosure of sensitive operational data, manipulation or deletion of critical monitoring information, and potential disruption of industrial processes. Given the role of Advantech iView in monitoring and managing industrial assets, a successful attack could degrade situational awareness or cause erroneous control decisions, impacting safety and operational continuity. The vulnerability's network accessibility and lack of authentication requirements increase the likelihood of exploitation by threat actors, including cybercriminals or nation-state actors targeting critical infrastructure. This could result in financial losses, regulatory penalties under GDPR for data breaches, and reputational damage. Additionally, disruption in critical infrastructure could have cascading effects on public services and economic stability in affected regions.

1. Immediately restrict access to UDP port 162 (SNMP trap) on Advantech iView systems using network firewalls or access control lists to allow only trusted management stations. 2. Implement network segmentation to isolate industrial monitoring systems from general enterprise networks and the internet. 3. Deploy intrusion detection/prevention systems (IDS/IPS) with signatures or anomaly detection for malicious SNMP trap payloads. 4. Monitor SNMP traffic logs for unusual or unexpected trap messages that could indicate exploitation attempts. 5. Coordinate with Advantech for official patches or updates addressing this vulnerability and apply them promptly once available. 6. If patching is delayed, consider disabling SNMP trap reception on iView if not essential, or use SNMPv3 with encryption and authentication where possible. 7. Conduct regular security assessments and penetration testing focused on industrial protocols and management interfaces. 8. Educate operational technology (OT) and IT teams about the risks of SNMP-based attacks and enforce strict change management procedures.
