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 · moderate confidence

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 IIJ SmartKey app is installed
    Open Android device Settings > Apps > Apps list and search for 'IIJ SmartKey' or 'SmartKey', or check the app drawer for the SmartKey icon
    Affected if IIJ SmartKey app is present on the device
  2. Find installed app version
    In Settings > Apps > IIJ SmartKey, scroll to the 'App info' or 'Version' field to display the installed version number (e.g., 2.1.3, 2.1.2, etc.)
    Affected if Version displayed is less than 2.1.4 or version info shows no number / is unknown
  3. Confirm version comparison
    Compare the displayed version against 2.1.4 - any version starting with 2.1.3, 2.1.2, 2.1.1, 2.1.0 or lower is affected
    Affected if Installed version is a release prior to 2.1.4 (e.g., 2.1.3, 2.1.0, 1.x.x)
  4. Check if OTP functionality is in use
    Determine whether the app is actively generating or storing one-time passwords for authentication purposes - look for OTP codes displayed in the app or configured authentication accounts
    Affected if App is actively used for OTP generation and version is below 2.1.4

A user is affected if IIJ SmartKey Android app is installed with any version prior to 2.1.4 and the app is being used for OTP-based authentication.
