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 Access CX App for Android prior to 2.0.0.1 and for iOS prior to 2.0.2 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 Access CX mobile application for Android and iOS fails to validate X.509 certificates when establishing SSL/TLS connections, allowing attackers on the same network to intercept communications through a man-in-the-middle attack by presenting a fraudulent certificate.

MitigationUpdate the Access CX app to version 2.0.0.1 or later for Android and version 2.0.2 or later for iOS, which implement proper SSL certificate validation.

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 the installed Access CX app version on Android
    Open Settings > Apps > Access CX (or Nissan Securities Access CX), then view the Version information. Alternatively, run `adb shell dumpsys package com.nissan.access` (replace with actual package name if different) and look for versionName or versionCode.
    Affected if The displayed version is 2.0.0.0 or lower (Android)
  2. Identify the installed Access CX app version on iOS
