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
A Time of Check Time of Use (TOCTOU) vulnerability was reported in the Lenovo Vantage SystemUpdate Plugin version 2.0.0.212 and earlier that could allow a local attacker to delete arbitrary files.

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

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 if Lenovo Vantage is installed
    Check for Lenovo Vantage installation by looking in Program Files or Program Files (x86) for 'Lenovo' folder, or check Add/Remove Programs for 'Lenovo Vantage' entry
    Affected if Lenovo Vantage is present on the system
  2. Locate the SystemUpdate Plugin version file
    Navigate to the Lenovo Vantage installation directory (typically C:\Program Files\Lenovo\Lenovo Vantage\) and look for the SystemUpdatePlugin.dll or a version info file; right-click the DLL and select Properties > Details to view the File Version
    Affected if SystemUpdate Plugin version is 2.0.0.212 or earlier (or version cannot be determined and the file exists)
  3. Locate the Hardware Scan Plugin version
    Check for HardwareScanPlugin.dll in the Lenovo Vantage installation directory and view its file version via Properties > Details
    Affected if Hardware Scan Plugin version is 1.3.1.2 or earlier (or version cannot be determined and the file exists)
  4. Locate the Hardware Scan Addin version
    Look for HardwareScanAddin.dll or a version file in the Lenovo Vantage directory and check its file version via Properties > Details
    Affected if Hardware Scan Addin version is 2.4.1.1 or earlier (or version cannot be determined and the file exists)
  5. Confirm vulnerable component is enabled
    Check if the Lenovo Vantage service is running and if the SystemUpdate Plugin feature is active; verify the plugin is loaded by examining running processes or Lenovo Vantage logs if accessible
    Affected if Lenovo Vantage service is running and the vulnerable plugin is loaded/enabled

A user is affected if any of the three plugins (SystemUpdate Plugin, Hardware Scan Plugin, or Hardware Scan Addin) are installed with a version lower than the fixed releases (2.0.0.213, 1.3.1.2, or 2.4.1.1 respectively) and the application is active on the system.
