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
Coordinate Plus App for Android 1.0.2 and earlier and Coordinate Plus App for iOS 1.0.2 and earlier do not verify SSL certificates.

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 Coordinate Plus mobile applications for Android and iOS versions 1.0.2 and earlier fail to validate SSL/TLS certificates during HTTPS connections. This allows man-in-the-middle attackers to intercept, read, and modify encrypted traffic by presenting invalid or self-signed certificates, since the app accepts any certificate without verification.

MitigationUpdate to Coordinate Plus App version 1.0.3 or later which implements proper SSL certificate validation. Until then, avoid using the app on untrusted networks.

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 Coordinate Plus app is installed
    On Android: Open Settings > Apps and search for 'Coordinate Plus'. On iOS: Search for 'Coordinate Plus' in the App Library or on the Home Screen
    Affected if Coordinate Plus app is found on the device
  2. Determine installed version on Android
    Go to Settings > Apps > Coordinate Plus and read the version number displayed under 'App info' or 'Version'
    Affected if Version displays as 1.0.2 or lower
  3. Determine installed version on iOS
    Open the App Store, search for 'Coordinate Plus', tap on the app, and note the version number shown in the app description
    Affected if Version displays as 1.0.2 or lower
  4. Confirm affected status
    Compare your identified version against the affected range: versions 1.0.2 and earlier are vulnerable. Versions 1.0.3 and later include the fix
    Affected if Installed version is 1.0.2 or earlier

If the Coordinate Plus app version is 1.0.2 or earlier, the app is vulnerable because it accepts any SSL certificate without validation, allowing traffic interception.
