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
During an internal security assessment, a potential vulnerability was discovered in Lenovo Diagnostics and the HardwareScanAddin used in Lenovo Vantage that, during installation or when using hardware scan, could allow a local authenticated user to perform an arbitrary file write with elevated 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 · moderate confidence

Lenovo Diagnostics and the HardwareScanAddin component in Lenovo Vantage contain a local privilege escalation vulnerability where an authenticated local user can perform arbitrary file writes with elevated (SYSTEM) privileges during installation or hardware scan operations. This could allow a local attacker to achieve code execution at elevated privilege levels.

MitigationApply vendor-supplied patches from Lenovo when available. Until then, restrict local user access to Lenovo Vantage/Diagnostics functionality and monitor for suspicious file activity in system directories.

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 Lenovo Vantage installation
    Open Programs and Features (appwiz.cpl) or check for Lenovo Vantage in the Start Menu, or look for the installation directory under C:\Program Files\Lenovo\Vantage or similar paths
    Affected if Lenovo Vantage is not installed on the system
  2. Identify Lenovo Vantage version
    Right-click on Lenovo Vantage in Programs and Features to view the version, or right-click the executable and view Properties > Details, or check the version in the software's About/Help section
    Affected if The installed version has not been patched and falls within the vulnerable version range
  3. Locate HardwareScanAddin component
    Search for HardwareScanAddin.dll or HardwareScanAddin in the Lenovo Vantage installation directory (typically under C:\Program Files\Lenovo\Vantage or C:\Program Files (x86)\Lenovo\Vantage)
    Affected if The HardwareScanAddin component is present in the installation
  4. Check for recent installation or scan activity
    Review Windows Event Viewer logs under Application and System logs for events related to Lenovo Diagnostics or HardwareScan operations, or check recent file activity in the Lenovo Vantage installation directory
    Affected if Recent installation, repair, or hardware scan operations have been performed on the system
  5. Verify local user access
    Check if standard (non-admin) local users have access to run Lenovo Vantage or Diagnostics tools, or check group membership for users who can access Lenovo Vantage functionality
    Affected if Standard local users can access and execute Lenovo Vantage or Diagnostics features

A user is affected if Lenovo Vantage with the HardwareScanAddin component is installed, the version is within the vulnerable range, and local non-privileged users have access to run the software.
