Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The smart.card (aka nh.smart.card) application 3.2 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

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 · high confidence

The smart.card (nh.smart.card) Android application version 3.2 fails to validate X.509 certificates during SSL/TLS server connections, enabling man-in-the-middle attackers to intercept encrypted communications by presenting fraudulent certificates and steal sensitive data.

MitigationUpgrade to a patched version of the application that implements proper X.509 certificate chain validation, or implement certificate pinning in the application's network layer to ensure connections only trust legitimate server certificates.

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. Identify if Nonghyup Smart Card app is installed
    On the Android device, go to Settings > Apps > look for 'Nonghyup Smart Card' or 'nh.smart.card' in the installed applications list
    Affected if The application named 'Nonghyup Smart Card', 'nh.smart.card', or 'Smart Card' is found on the device
  2. Check the installed version number
    Tap on the app in Settings > Apps, then look at the 'Version' or 'Version info' field under App info; alternatively, check the APK file metadata if the APK is available
    Affected if The version displayed is exactly 3.2
  3. Confirm the package identifier
    In Settings > Apps, verify the package name is 'nh.smart.card' or com.nonghyup.smartcard
    Affected if The package name matches nh.smart.card and version is 3.2

If the Nonghyup Smart Card Android application with package identifier nh.smart.card is installed and its version is exactly 3.2, the device is affected by this CVE.

Mitigation

Upgrade to a patched version of the application that implements proper X.509 certificate chain validation, or implement certificate pinning in the application's network layer to ensure connections only trust legitimate server certificates.
