Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

SQL injection vulnerability in Advantech iView's CUtils.checkSQLInjection() function allows authenticated users with at least user-level privileges to inject malicious SQL queries, potentially exposing sensitive database information or causing denial-of-service conditions.

MitigationImplement proper parameterized queries or prepared statements in the CUtils.checkSQLInjection() function and validate/sanitize all user inputs before SQL execution. Apply vendor-provided patches when available.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Advantech iView installation
    Locate the iView application installation directory, typically found in C:\Program Files\Advantech\iView or similar paths on the server. Check for the presence of iView application files and the management console.
    Affected if Advantech iView software is present on the system
  2. Identify installed iView version
    Access the iView web interface or management console and navigate to the About/Help section to view the software version. Alternatively, check version files in the installation directory.
    Affected if The installed version is lower than 5.7.05.7057
  3. Verify user authentication is enabled
    Check iView's user management configuration to confirm that authentication is required for accessing the application. Review the user accounts and privilege levels configured in the system.
    Affected if User authentication is configured and users with at least user-level privileges can access the application
  4. Confirm CUtils module availability
    Inspect the application deployment for the presence of CUtils class or check the web application's class files and libraries for the checkSQLInjection() function implementation.
    Affected if The CUtils.checkSQLInjection() method is present in the deployed application

A user is affected if Advantech iView is installed with a version lower than 5.7.05.7057 and the application is accessible to authenticated users with at least user-level privileges.
