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 checksWork through these to decide whether this CVE applies to you.
-
Check if Lenovo System Interface Foundation is installedOpen Programs and Features (appwiz.cpl) or check for the presence of the Lenovo System Interface Foundation folder in Program Files (typically C:\Program Files\Lenovo\System Interface Foundation or C:\Program Files (x86)\Lenovo\System Interface Foundation)Affected if The application is not listed in Programs and Features or the folder does not exist, meaning the product is not installed and the user is not affected by this CVE.
-
Find the installed version via Windows RegistryOpen Registry Editor (regedit) and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Lenovo\System Interface Foundation (or HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Lenovo\System Interface Foundation for 32-bit on 64-bit systems). Look for a Version or DisplayVersion value.Affected if The version value shown is less than 1.1.19.3, indicating the installed version is vulnerable.
-
Check file version of the main executableLocate the main executable (typically SystemInterfaceFoundation.exe or similar in the installation directory), right-click the file, select Properties, and view the Details tab for the File Version.Affected if The file version displayed is earlier than 1.1.19.3, meaning the environment is affected.
-
Verify if Lenovo System Interface Foundation service is runningOpen Services (services.msc), locate any Lenovo System Interface Foundation related service, and check its status. Alternatively, run `sc query` or check Task Manager for running Lenovo processes.Affected if The service or process is running on a version earlier than 1.1.19.3, making the privilege escalation vulnerability exploitable.
A user is affected if Lenovo System Interface Foundation is installed with a version earlier than 1.1.19.3 and the application or its service is present on the system.
