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
Advantech iView versions prior to v5.7.04 build 6425 contain a vulnerability within the SNMP management tool that allows for remote attackers to bypass authentication checks and reach a SQL injection vulnerability within the ‘search_term’ parameter to the ‘NetworkServlet’ endpoint. Successful exploitation allows for remote code execution with administrator privileges.

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 · high confidence

Advantech iView versions before v5.7.04 build 6425 contain an authentication bypass in the SNMP management tool that allows unauthenticated remote attackers to reach a SQL injection vulnerability in the 'search_term' parameter of the NetworkServlet endpoint. Chaining these vulnerabilities enables remote code execution with administrator privileges.

MitigationUpgrade to iView v5.7.04 build 6425 or later. If immediate patching is not feasible, restrict network access to the SNMP management interface and implement WAF rules to block SQL injection patterns in the 'search_term' parameter.

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. Identify Advantech iView installation and version
    Locate the iView installation directory (commonly C:\Program Files\Advantech\iView or similar on Windows, or /opt/iview on Linux). Check for a version file, or right-click the application executable and select Properties > Details to view the File Version. Alternatively, check the Windows Services list for 'Advantech iView' service and its associated executable path.
    Affected if The installed version is revealed to be lower than 5.7.04.6425 (for example, 5.7.03 or any build number below 6425).
  2. Verify SNMP management interface is accessible
    Confirm that the SNMP management tool interface is exposed on the network. This is typically accessible on UDP port 161 or a custom port configured during iView setup. Check firewall rules and network exposure for any inbound access to SNMP ports on the iView server.
    Affected if The SNMP management interface is reachable from untrusted networks or is enabled without network segmentation.
  3. Confirm NetworkServlet endpoint is exposed
    Identify if the NetworkServlet endpoint is accessible. This endpoint typically responds at a path containing '/NetworkServlet' (such as /iview/NetworkServlet or similar depending on deployment). Use a web request to the known endpoint URL with any valid parameter to test for availability.
    Affected if The NetworkServlet endpoint is reachable without authentication (the authentication bypass is the entry point for the SQL injection).

A user is affected if Advantech iView is installed with a version lower than 5.7.04 build 6425 AND the SNMP management interface is exposed, allowing unauthenticated access to the NetworkServlet endpoint containing the SQL injection vulnerability.

Upgrade available Upgrade to 5.7.04.6425 or later
Fixed in 5.7.04.6425
Interim mitigation

Upgrade to iView v5.7.04 build 6425 or later. If immediate patching is not feasible, restrict network access to the SNMP management interface and implement WAF rules to block SQL injection patterns in the 'search_term' parameter.

Recommended fix High confidence

v5.7.04 build 6425

  1. Backup the current iView installation and database before proceeding with the upgrade
  2. Download Advantech iView version 5.7.04 build 6425 or later from the official Advantech support portal (www.advantech.tw)
  3. Stop the iView service to ensure no active connections during upgrade
  4. Install or apply the upgraded version following the standard installation procedure
  5. Start the iView service after the upgrade completes
  6. Verify the version number reflects 5.7.04.6425 or later in the application
  7. Test critical functionality including the SNMP management tool and NetworkServlet endpoint to confirm proper operation
Caveat Standard practice recommends testing the upgrade in a non-production environment before deploying to production
