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. Locate Lenovo App Store executable
    Search for lenovoappstore.exe in common installation directories such as C:\Program Files\Lenovo\Lenovo App Store or C:\Program Files (x86)\Lenovo\Lenovo App Store, or use 'Get-ChildItem -Path C:\Program Files* -Recurse -Filter lenovoappstore.exe -ErrorAction SilentlyContinue'
    Affected if The executable exists on the system
  2. Retrieve installed version
    Right-click the lenovoappstore.exe file, select Properties, then view the Details tab for the Product version, or run '(Get-Item "C:\Program Files\Lenovo\Lenovo App Store\lenovoappstore.exe").VersionInfo.ProductVersion'
    Affected if Version number is lower than 9.0.2530.1027
  3. Check registry for version
    Run 'Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*" | Where-Object {$_.DisplayName -like "*Lenovo App Store*"} | Select-Object DisplayVersion, InstallLocation' or check HKLM:\SOFTWARE\Lenovo\Lenovo App Store for version keys
    Affected if Registry shows a version lower than 9.0.2530.1027 or the registry key does not exist (indicating older unpatched version)
  4. Verify the installation service exists
    Run 'Get-Service -Name *Lenovo*AppStore* -ErrorAction SilentlyContinue' or check services.msc for a Lenovo App Store update/installation service
    Affected if The service is present and running on versions below 9.0.2530.1027

If Lenovo App Store is installed and its version is below 9.0.2530.1027, the environment is vulnerable to local privilege escalation via improper permission controls during app installation.
