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 Samsung Cloud is installed
    Inspect the installed programs list on the system, or check common installation directories for Samsung Cloud client software. On Windows, this can be done via Control Panel > Programs and Features, or by searching for 'Samsung Cloud' in the start menu.
    Affected if Samsung Cloud client software is present on the system
  2. Determine the installed version of Samsung Cloud
    Right-click on the Samsung Cloud application in the programs list and select 'Properties' or 'Change', or right-click the application shortcut and select 'Properties' to view the version information in the 'Details' or 'Version' field.
    Affected if The displayed version number is lower than 4.7.0.3
  3. Verify the exact version number against the affected range
    Compare the installed version string to the affected range. Note that version comparisons should account for full version strings (e.g., 4.7.0.1, 4.5.2, etc.).
    Affected if The installed version falls below 4.7.0.3 (e.g., 4.7.0.2, 4.6.x, 4.5.x, or any earlier version)

A user is affected if Samsung Cloud client software is installed and its version number is less than 4.7.0.3.
