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. Verify Samsung Smart Switch is installed
    Check for the application in the Windows registry at HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ or look in C:\Program Files\Samsung\Smart Switch\ or C:\Program Files (x86)\Samsung\Smart Switch\
    Affected if Samsung Smart Switch is found on the system
  2. Identify installed version
    Locate the version information in the registry uninstall key or right-click the Smart Switch executable, select Properties, and view the File Version under the Details tab
    Affected if The version shown is blank, unreadable, or cannot be determined
  3. Compare version to affected range
    Compare your installed version number against 4.3.23043_3. The first three numbers (4.3.23043) are the primary version; the _3 is a build suffix
    Affected if The installed version is 4.3.23043_2, 4.3.23042, 4.3.23040, or any version where the numeric portion is less than 23043
  4. Check for installation anomalies
    Examine the Smart Switch installation directory for any directory junctions, broken symlinks, or unusually named folders that did not exist after a clean installation
    Affected if Unexpected directory junctions or symlinks are present in the installation folder or surrounding directories
  5. Verify installer was run with elevated privileges
    Review Windows Event Viewer logs under Windows Logs > Application for Smart Switch installer events, checking if the installer executed with administrator privileges
    Affected if The installer historically ran with elevated privileges and version is below 4.3.23043_3

The environment is affected if Samsung Smart Switch PC is installed with any version prior to 4.3.23043_3, as the installer vulnerability exists in those versions.
