CVE-2025-48891 Advantech CVE debrief

Who should care

Organizations using Advantech iView, especially teams operating OT or industrial environments, should treat this as important if the application is deployed anywhere authenticated users can reach it. Administrators responsible for patching, access control, and application monitoring should prioritize review.

Technical summary

CISA assigns CVE-2025-48891 a CVSS 3.1 score of 7.6 (HIGH) with vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L. The issue is an SQL injection condition in CUtils.checkSQLInjection() affecting Advantech iView < 5.7.05_build_7057. The advisory states exploitation requires an authenticated attacker with at least user-level privileges and may lead to information disclosure or a denial-of-service condition.

Defensive priority

High. The flaw is network-reachable, low-complexity, and requires only low-privilege authenticated access, which makes remediation important for any exposed or broadly accessible iView deployment.

Recommended defensive actions

• Upgrade Advantech iView to v5.7.05 build 7057 as recommended in the advisory.
• Inventory deployments and verify no systems remain on versions earlier than 5.7.05_build_7057.
• Review authenticated access paths to iView and reduce user-level exposure where possible.
• Monitor logs and application behavior for unusual SQL errors or denial-of-service symptoms until patching is complete.

Evidence notes

Primary evidence comes from CISA CSAF advisory ICSA-25-191-08 for Advantech iView, which states the affected version range, the vulnerable CUtils.checkSQLInjection() function, the authenticated user-level attack requirement, and the recommended update. The CVE record and CISA advisory page provide official cross-reference points for the same vulnerability.
