CVE-2025-34247
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 · uneditedAdvantech WebAccess/VPN versions prior to 1.1.5 contain a SQL injection vulnerability in NetworksController.addNetworkAction() that allows an authenticated low-privileged observer user to inject SQL via datatable search parameters, leading to disclosure of database information.
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 confidenceAdvantech WebAccess/VPN versions prior to 1.1.5 have a SQL injection vulnerability in the NetworksController.addNetworkAction() method. An authenticated user with low observer privileges can inject malicious SQL via datatable search parameters, enabling disclosure of database schema and contents.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed WebAccess/VPN versionLocate the WebAccess/VPN application version through the product interface, about dialog, installation logs, or configuration files. Compare the discovered version against the affected range.Affected if The installed version is less than 1.1.5
-
Confirm NetworksController component existsInspect the WebAccess/VPN application deployment to verify the presence of the NetworksController class which contains the vulnerable addNetworkAction() method.Affected if The NetworksController with addNetworkAction() method is present in the application
-
Verify user authentication is enabledReview the WebAccess/VPN authentication configuration to confirm user login is required for access, since exploitation requires an authenticated session.Affected if User authentication is required and observer-level user accounts can be created or already exist
-
Check datatable search functionality exposureDetermine whether the datatable search parameters in the addNetworkAction() endpoint are accessible to authenticated users, as this is the injection vector.Affected if The datatable search interface in addNetworkAction() is accessible to authenticated users with observer privileges
Your environment is affected if WebAccess/VPN is installed at a version prior to 1.1.5, the NetworksController module is present, and authenticated users with observer privileges can access the datatable search parameters in addNetworkAction().

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.1.5
Upgrade to WebAccess/VPN version 1.1.5 or later, which contains the security patch for this vulnerability. If immediate upgrade is not possible, implement input validation and parameterized queries for the affected endpoint.
1.1.5
- Obtain the WebAccess/VPN version 1.1.5 release from the official Advantech download channels (icr.advantech.com or through official support)
- Backup the current WebAccess/VPN installation and database before performing the upgrade
- Install version 1.1.5 of WebAccess/VPN following the standard upgrade procedure
- Verify the upgrade was successful by checking the version number in the product interface
- Confirm the NetworksController.addNetworkAction() endpoint is no longer vulnerable to SQL injection via datatable search parameters
