CVE-2025-53475 is a high-severity vulnerability affecting Advantech iView, a product commonly used in industrial and infrastructure monitoring environments. The vulnerability is classified as CWE-89, indicating it is an SQL Injection flaw. Specifically, the issue resides in the NetworkServlet.getNextTrapPage() function, where certain input parameters are not properly sanitized. This improper input validation allows an authenticated attacker with at least user-level privileges to inject malicious SQL commands. Exploiting this flaw can lead to remote code execution (RCE) under the context of the 'NT AUTHORITY\LOCAL SERVICE' account, which is a highly privileged local system account in Windows environments. The vulnerability requires no user interaction beyond authentication, and the attacker can leverage it to compromise the confidentiality, integrity, and availability of the affected system. The CVSS v3.1 base score is 8.8, reflecting the ease of exploitation over the network (AV:N), low attack complexity (AC:L), and the requirement for low privileges (PR:L) but no user interaction (UI:N). The scope is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). No known exploits are currently reported in the wild, and no patches have been linked yet. However, given the nature of the vulnerability and the privileged context of code execution, this represents a significant risk to organizations using Advantech iView, especially in critical infrastructure or industrial control system (ICS) environments where this product is deployed.

For European organizations, the impact of this vulnerability can be substantial. Advantech iView is often used in industrial automation, manufacturing, and critical infrastructure sectors such as energy, transportation, and utilities. A successful exploitation could allow attackers to manipulate monitoring data, disrupt operational technology (OT) processes, or gain persistent footholds within networks. This could lead to operational downtime, safety hazards, data breaches, and loss of control over critical systems. Given the high privileges under which the code executes, attackers could potentially move laterally within networks, escalate privileges further, or deploy ransomware or other malware payloads. The confidentiality of sensitive operational data could be compromised, and integrity of system states could be undermined, leading to incorrect decision-making or physical damage. The availability of monitoring and control systems could also be affected, causing service interruptions. Such impacts are particularly critical in sectors regulated under EU directives for cybersecurity and critical infrastructure protection, potentially leading to regulatory penalties and reputational damage.

To mitigate this vulnerability, European organizations should prioritize the following actions: 1) Implement strict access controls to limit user-level privileges on Advantech iView systems, ensuring only trusted personnel have authenticated access. 2) Monitor and audit authentication logs and application usage to detect suspicious activities indicative of exploitation attempts. 3) Employ network segmentation to isolate Advantech iView systems from broader enterprise networks, reducing the attack surface and limiting lateral movement. 4) Apply virtual patching via web application firewalls (WAFs) or intrusion prevention systems (IPS) that can detect and block SQL injection patterns targeting the vulnerable function. 5) Engage with Advantech for official patches or updates and plan for timely deployment once available. 6) Conduct regular vulnerability assessments and penetration testing focused on industrial control systems to identify and remediate similar issues proactively. 7) Educate system administrators and operators about the risks of SQL injection and the importance of secure coding and input validation practices. These measures, combined, will reduce the likelihood and impact of exploitation.
