CVE-2025-13373 is a critical SQL Injection vulnerability identified in Advantech iView, a widely used industrial monitoring and management platform. The vulnerability exists because the software fails to properly sanitize SNMP v1 trap requests received on UDP port 162. SNMP traps are unsolicited notifications sent by network devices to management systems; in this case, iView processes these traps without adequate input validation. An attacker can craft malicious SNMP trap payloads containing SQL commands that, when processed by iView, are executed against its backend database. This improper neutralization of special elements in SQL commands (CWE-89) allows remote, unauthenticated attackers to manipulate database queries, potentially leading to unauthorized data disclosure, data modification, or denial of service. The vulnerability does not require any authentication or user interaction, and the attack surface is exposed over the network, increasing the risk of exploitation. Although no public exploits have been reported yet, the high CVSS score of 8.7 underscores the severity and potential impact. The vulnerability affects version 5.7.05.7057 and earlier, and no official patches have been linked yet, indicating that organizations must rely on compensating controls until a fix is released. Given Advantech iView's role in industrial control systems and critical infrastructure monitoring, exploitation could disrupt operations or compromise sensitive industrial data.

For European organizations, especially those in critical infrastructure sectors such as energy, manufacturing, transportation, and utilities, this vulnerability poses a significant threat. Successful exploitation could lead to unauthorized access to sensitive operational data, manipulation of industrial processes, or disruption of monitoring capabilities. This can result in operational downtime, safety hazards, regulatory non-compliance, and financial losses. The ability to execute arbitrary SQL commands without authentication means attackers could extract confidential information, alter system configurations, or delete critical data, severely impacting the integrity and availability of industrial control systems. Given the increasing reliance on industrial IoT and monitoring platforms like Advantech iView in Europe, the risk extends to national critical infrastructure resilience and industrial competitiveness.

1. Immediately restrict access to UDP port 162 (SNMP trap port) at network boundaries using firewalls or access control lists to allow only trusted management systems. 2. Implement network segmentation to isolate Advantech iView servers from untrusted networks and limit exposure to potential attackers. 3. Deploy intrusion detection/prevention systems (IDS/IPS) with signatures or anomaly detection capabilities for malicious SNMP traffic. 4. Monitor SNMP trap traffic for unusual or malformed packets indicative of exploitation attempts. 5. Engage with Advantech for official patches or updates addressing this vulnerability and plan prompt deployment once available. 6. Consider disabling SNMP trap reception on iView if not required operationally. 7. Conduct regular security assessments and penetration testing focused on industrial control system components to identify similar weaknesses. 8. Maintain up-to-date asset inventories to quickly identify affected systems and prioritize remediation efforts.
