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
MITRE is populating this ID because it was assigned prior to Lenovo becoming a CNA. A local privilege escalation vulnerability was reported (fixed and publicly disclosed in 2015) in Lenovo System Update version 5.07.0008 and prior where the SUService.exe /type COMMAND type could allow a user to execute arbitrary code 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 · high confidence

A local privilege escalation vulnerability in Lenovo System Update version 5.07.0008 and prior allows local users to execute arbitrary code with elevated privileges via the SUService.exe service when invoked with the /type COMMAND parameter. The service improperly validates or does not properly restrict the command execution, enabling a low-privilege user to gain SYSTEM-level access.

MitigationUpdate Lenovo System Update to a version newer than 5.07.0008. As this is a local privilege escalation, ensure proper access controls and monitor for unauthorized access to the affected system.

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. Check if Lenovo System Update is installed
    Open Windows Control Panel, go to Programs and Features, or run 'Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -like "*Lenovo System Update*"}' in PowerShell
    Affected if Lenovo System Update appears in the installed programs list
  2. Determine the installed version of Lenovo System Update
    In Programs and Features, locate Lenovo System Update and note the version column, or check the registry key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{GUID}\DisplayVersion
    Affected if The version listed is 5.07.0008 or any version lower than 5.07.0008
  3. Locate the SUService.exe file
    Search for SUService.exe in typical installation paths such as C:\Program Files\Lenovo\System Update\ or C:\Program Files (x86)\Lenovo\System Update\, or use 'Get-ChildItem -Path "C:\Program Files" -Recurse -Filter "SUService.exe" -ErrorAction SilentlyContinue'
    Affected if SUService.exe exists in a Lenovo System Update directory
  4. Verify the SUService.exe version
    Right-click the SUService.exe file, go to Properties, and check the Details tab for the File Version, or run 'Get-Item "path\to\SUService.exe" | Select-Object VersionInfo | Format-List *'
    Affected if The file version is 5.07.0008 or lower
  5. Check if the SUService service is running
    Open Services (services.msc), locate 'Lenovo System Update Service' or 'SUService', and check its Status, or run 'Get-Service -Name *Lenovo* -ErrorAction SilentlyContinue' in PowerShell
    Affected if The service is installed and running with SYSTEM or elevated privileges

Your environment is affected if Lenovo System Update version 5.07.0008 or lower is installed and the SUService.exe service is present and executable by a low-privilege user.
