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
An improper access restriction in NI MeasurementLink Python services could allow an attacker on an adjacent network to reach services exposed on localhost. These services were previously thought to be unreachable outside of the node. This affects measurement plug-ins written in Python using version 1.1.0 of the ni-measurementlink-service Python package and all previous 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 · high confidence

This is an improper access control vulnerability in NI MeasurementLink Python services where services bound to localhost were inadvertently exposed to adjacent networks. An attacker on the same network segment can reach these previously localhost-only services, potentially executing measurements or accessing sensitive data. The issue affects ni-measurementlink-service Python package version 1.1.0 and all prior versions.

MitigationUpgrade to a patched version of the ni-measurementlink-service package and verify that services are properly bound to localhost only or have appropriate network access controls in place.

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. Verify ni-measurementlink-service package installation
    Run 'pip show ni-measurementlink-service' or check your Python environment's installed packages to confirm the package is present
    Affected if The package is installed and its version is 1.1.0 or earlier (or any version below 1.1.1)
  2. Determine the installed package version
    Use pip or your package manager to list the exact version number of the ni-measurementlink-service package
    Affected if The installed version falls within the range >= 1.0.0 and < 1.1.1
  3. Inspect service binding configuration
    Examine your MeasurementLink service configuration files or startup scripts to identify the network binding address used by your services
    Affected if Services are configured to bind to all interfaces (0.0.0.0) or a non-localhost address rather than localhost only (127.0.0.1)
  4. Test network accessibility of services
    From a separate machine on the same network segment, attempt to reach the MeasurementLink service ports using the target machine's IP address rather than localhost
    Affected if Services respond to network requests from adjacent hosts on ports they should only be listening on locally

You are affected if you have ni-measurementlink-service version 1.1.0 or earlier installed AND your services are accessible from network addresses rather than being restricted to localhost-only connections.

Upgrade available Upgrade to 1.1.1 or later
Fixed in 1.1.1
Interim mitigation

Upgrade to a patched version of the ni-measurementlink-service package and verify that services are properly bound to localhost only or have appropriate network access controls in place.

Recommended fix High confidence

1.1.1

  1. Identify the current version of the ni-measurementlink-service package in your Python environment using 'pip show ni-measurementlink-service'
  2. Upgrade the package to version 1.1.1 or later by running: pip install --upgrade ni-measurementlink-service>=1.1.1
  3. Verify the installed version matches the requirement: pip show ni-measurementlink-service
  4. If you have deployed measurement plug-ins to production systems, restart any running MeasurementLink services to ensure they load the updated package
  5. Confirm the upgrade was successful by checking that the service version is now 1.1.1 or higher
