CVE-2026-9142
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 · uneditedThere is an insecure default credentials vulnerability in NI grpc-device when TLS configuration is not present and the server is bound beyond loopback. This may allow an unauthenticated user access to the server on the local network. This affects NI grpc-device 2.17.0 and prior versions.
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 confidenceNI grpc-device server versions 2.17.0 and prior contain insecure default credentials that are exposed when TLS configuration is omitted and the server binds to a network-accessible interface (non-loopback). Attackers on the local network can authenticate without credentials, achieving unauthenticated access to the gRPC device server.

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 grpc-device server installationLocate the grpc-device server executable or service on the system (commonly found in NI installation directories such as C:\Program Files\National Instruments\ or /usr/local/ni/). Check for grpc-device-server.exe or ni_grpc_device_server service.Affected if The grpc-device server software is installed on the system.
-
Determine installed grpc-device server versionRun the grpc-device server with a version flag (such as --version) or inspect the server binary properties/details. Compare the version number against the affected range: versions 2.17.0 and prior, or InstrumentStudio versions 2025 and 2026.Affected if The installed version is 2.17.0 or earlier, or InstrumentStudio 2025/2026 is in use.
-
Inspect TLS configuration statusExamine the grpc-device server configuration file or startup parameters for TLS settings. Look for flags such as --tls, --use_ssl, or similar TLS-enabling options. Check whether SSL/TLS certificates are configured.Affected if TLS configuration is omitted or disabled on the server.
-
Verify server binding interfaceReview the server configuration or runtime logs to determine which network interface the server is bound to. Look for binding to 0.0.0.0 (all interfaces), the machine hostname IP, or any non-loopback address, versus 127.0.0.1 (loopback only).Affected if The server binds to a network-accessible interface (non-loopback address).
-
Confirm network accessibilityCheck if the server is listening on a non-loopback IP address by running network status commands (such as netstat -an) and looking for the grpc-device server port (typically port 3581) bound to an external IP.Affected if The server listens on an IP address other than 127.0.0.1.
The environment is affected if grpc-device server version 2.17.0 or earlier (or InstrumentStudio 2025/2026) is running with TLS disabled and bound to a non-loopback interface, allowing unauthenticated network access.

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 · scoped2.18.0
Enable TLS configuration and proper authentication mechanisms on the grpc-device server; if network access is unnecessary, bind exclusively to loopback interface; otherwise update to a patched version when available.
NI grpc-device server version 2.18.0 or later
- 1. Identify the currently installed NI grpc-device server version by checking the application or service details
- 2. Download NI grpc-device server version 2.18.0 or later from the official NI website (www.ni.com) or official NI distribution channels
- 3. Back up any existing configuration files for the NI grpc-device server
- 4. Uninstall or stop the current NI grpc-device server instance
- 5. Install the updated NI grpc-device server version 2.18.0 or later
- 6. Restore the backed-up configuration files to the new installation
- 7. Start the NI grpc-device server and verify it is running correctly
- 8. Confirm TLS configuration is properly enabled for production deployments (this vulnerability only manifests when TLS is not configured and server is bound beyond loopback)
