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 A Very Short History of Japan (aka com.ireadercity.c51) application 3.0.2 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 Android application fails to validate X.509 certificates during SSL/TLS connections, allowing man-in-the-middle attackers to intercept encrypted traffic by presenting fraudulent certificates and spoof legitimate servers.

MitigationImplement proper SSL certificate validation including chain-of-trust verification and hostname checking, or employ certificate pinning for sensitive endpoints.

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 if the vulnerable app is installed
    Check your Android device for the application named 'Ireadercity A Very Short History Of Japan' in Settings > Apps or using a package manager tool like 'pm list packages' via ADB
    Affected if The app is present on the device
  2. Confirm the installed version is 3.0.2
    Open the app info page in Settings > Apps > [app name] and check the version, or use 'dumpsys package [package_name]' via ADB to retrieve version details
    Affected if The installed version is exactly 3.0.2
  3. Determine if the app uses network connections
    Monitor the app's network activity using Android's built-in netstat, a packet capture tool like Wireshark on a rooted device, or by checking app permissions for network access
    Affected if The app makes outbound network connections using SSL/TLS

You are affected if the app 'Ireadercity A Very Short History Of Japan' version 3.0.2 is installed and it makes SSL/TLS connections, as the vulnerability lies in the app's failure to validate X.509 certificates during such connections.
