Advantech WebAccess/SCADA version 9.2.1 contains a SQL injection vulnerability identified as CVE-2025-46268, classified under CWE-89. SQL injection vulnerabilities occur when untrusted input is improperly sanitized, allowing attackers to manipulate backend SQL queries. In this case, an attacker with low privileges (PR:L) can remotely exploit the vulnerability without requiring user interaction (UI:N) to execute arbitrary SQL commands. This can lead to unauthorized data access, modification, or deletion, impacting confidentiality, integrity, and availability of the SCADA system. The vulnerability is remotely exploitable over the network (AV:N) and does not require complex attack conditions (AC:L). The CVSS v3.1 base score is 6.3, indicating a medium severity level. No public exploits have been reported yet, but the vulnerability poses a risk to industrial control environments where WebAccess/SCADA is deployed. The lack of available patches at the time of publication necessitates immediate risk mitigation through compensating controls. Given the critical role of SCADA systems in industrial automation, exploitation could disrupt operational processes or lead to data compromise.

For European organizations, especially those in critical infrastructure sectors such as energy, manufacturing, and utilities, this vulnerability could lead to unauthorized access to sensitive operational data and control commands. Exploitation might allow attackers to alter system configurations, disrupt industrial processes, or exfiltrate confidential information, potentially causing operational downtime and safety hazards. The impact extends to regulatory compliance risks under GDPR and NIS Directive frameworks due to potential data breaches and service disruptions. The medium severity score reflects moderate but tangible risks that could escalate if combined with other vulnerabilities or insider threats. Organizations relying on Advantech WebAccess/SCADA version 9.2.1 should consider this vulnerability a serious concern given the critical nature of SCADA systems in European industrial environments.

1. Monitor Advantech’s official channels for patches addressing CVE-2025-46268 and apply them promptly once released. 2. Restrict network access to the WebAccess/SCADA interface using firewalls and VPNs, limiting exposure to trusted administrators only. 3. Implement strict input validation and sanitization on all user inputs interacting with the SCADA system to prevent injection attacks. 4. Employ network segmentation to isolate SCADA systems from general IT networks, reducing attack surface. 5. Conduct regular security audits and penetration testing focused on injection vulnerabilities within industrial control systems. 6. Deploy intrusion detection and prevention systems (IDS/IPS) tuned to detect anomalous SQL queries or suspicious traffic patterns targeting SCADA components. 7. Enforce the principle of least privilege for user accounts accessing the SCADA system to minimize potential damage from compromised credentials. 8. Maintain comprehensive logging and monitoring to detect early signs of exploitation attempts.
