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
    Look for Lenovo System Update in the list of installed programs via Control Panel > Programs and Features, or query the Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for an entry named 'Lenovo System Update'
    Affected if The program is not present in the installed programs list
  2. Determine the installed version
    Locate the executable (typically in C:\Program Files\Lenovo\System Update\ or C:\Program Files (x86)\Lenovo\System Update\) and check its version property, or query the registry key HKLM\SOFTWARE\Lenovo\System Update for a Version value
    Affected if Unable to determine version or version information is missing
  3. Compare version to the affected range
    Compare the installed version number to 5.07.0084 - any version lower than 5.07.0084 is affected
    Affected if Installed version is less than 5.07.0084 (for example, 5.07.0080 or 5.06.0012)
  4. Verify if System Update service is running
    Open Services (services.msc) and check if the 'System Update' service exists and its status, or run 'sc query SystemUpdate' from command prompt
    Affected if The service is installed and running - only then can the log file vulnerability be exploited

You are affected if Lenovo System Update is installed with a version lower than 5.07.0084 and the System Update service is currently running on your machine.
