CVE-2025-53475 Advantech CVE debrief

Who should care

Administrators and operators of Advantech iView, especially teams responsible for OT/ICS management systems, should treat this as a priority patching item. Security teams should also review any environments where lower-privileged authenticated users can reach iView interfaces.

Technical summary

The advisory describes a flaw in NetworkServlet.getNextTrapPage() where certain parameters are not properly sanitized. Because the attack requires authentication, the initial access condition is lower than a public unauthenticated issue, but the impact can still be severe: SQL injection may be used as a stepping stone to code execution in the context of the Local Service account. The supplied CVSS vector is CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, which aligns with network exposure, low complexity, and high confidentiality, integrity, and availability impact.

Defensive priority

High. The combination of authenticated network access, SQL injection, and potential remote code execution warrants prompt remediation, especially on exposed or shared iView instances.

Recommended defensive actions

• Update Advantech iView to v5.7.05 build 7057 as recommended by the vendor.
• Inventory iView deployments and identify any instances running versions earlier than 5.7.05_build_7057.
• Review who has authenticated access to iView and remove unnecessary user-level accounts or access paths.
• Monitor for suspicious requests targeting NetworkServlet.getNextTrapPage() and investigate abnormal authentication or database-related activity.
• Prioritize remediation on systems that are reachable from broader enterprise networks or are used in operational environments.

Evidence notes

This debrief is based on the supplied CISA CSAF advisory for ICSA-25-191-08, which names Advantech iView as the affected product, specifies versions before 5.7.05_build_7057, and recommends updating to v5.7.05 build 7057. The official CVE and NVD records are included as corroborating references in the source corpus.
