DescriptionCVE.org

A vulnerability exists in Advantech iView that could allow for SQL injection through the CUtils.checkSQLInjection() function. This vulnerability can be exploited by an authenticated attacker with at least user-level privileges, potentially leading to information disclosure or a denial-of-service condition.

AnalysisAI

CVE-2025-48891 is a SQL injection vulnerability in Advantech iView's CUtils.checkSQLInjection() function that fails to properly sanitize user input, allowing authenticated attackers with user-level privileges to execute arbitrary SQL queries. This can lead to unauthorized information disclosure or denial-of-service conditions. The vulnerability requires network access and user authentication but has no UI interaction requirement, making it a significant risk for organizations using iView in multi-user environments.

Technical ContextAI

This vulnerability exists in Advantech iView, a web-based industrial data visualization and management platform. The root cause is classified under CWE-89 (SQL Injection), indicating that the CUtils.checkSQLInjection() utility function—intended as a security control—contains a bypass or implementation flaw that allows malicious SQL code to pass through validation. Rather than properly parameterizing queries or using prepared statements, the function likely performs inadequate input validation or uses a blacklist approach that can be circumvented. The vulnerability is particularly dangerous because it exists in a function explicitly designed for SQL injection prevention, suggesting a logic error in the validation mechanism itself. Affected systems are those running vulnerable versions of Advantech iView, a platform commonly deployed in industrial control systems, manufacturing, and critical infrastructure environments.

RemediationAI

IMMEDIATE: Apply vendor patch from Advantech when available (check Advantech Product Security Advisory page for CVE-2025-48891). 2) INTERIM MITIGATIONS: Restrict database account privileges used by iView to minimum required (principle of least privilege); implement network segmentation to limit iView access to trusted administrative users only; disable or isolate iView instances not in active use. 3) DETECTION: Monitor database query logs for suspicious SQL patterns; audit user access to iView; implement Web Application Firewall (WAF) rules to detect SQL injection patterns in HTTP requests to iView endpoints. 4) LONG-TERM: Upgrade to patched iView version when released; conduct code review of custom CUtils implementations if any exist; implement parameterized queries/prepared statements organization-wide.
