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 Zipcar (aka com.zc.android) application 3.4.2 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 Zipcar Android application version 3.4.2 fails to validate X.509 certificates from SSL servers during HTTPS connections, allowing attackers to perform man-in-the-middle attacks by presenting fraudulent certificates. This enables interception and theft of sensitive user data transmitted between the app and servers.

MitigationImplement proper SSL/TLS certificate validation in the Android app, including certificate pinning or robust trust manager configuration to verify server certificates against trusted Certificate Authorities.

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 Zipcar app version
    Open the Zipcar app, or go to Settings > Apps > Zipcar on the Android device, or check in the Google Play Store under My Apps > Zipcar to view the installed version
    Affected if The displayed version is exactly 3.4.2
  2. Confirm Android OS version
    Go to Settings > About Phone on the Android device to see the OS version
    Affected if The app runs on Android (the vulnerability description specifies the Android app)
  3. Verify certificate validation behavior
    Use a man-in-the-middle proxy tool (such as Burp Suite or OWASP ZAP) configured with an invalid or self-signed certificate, then attempt to intercept traffic while using the Zipcar app
    Affected if The app successfully connects to servers and transmits data even with an invalid certificate present, indicating no certificate validation

The environment is affected if the Zipcar Android app version 3.4.2 is installed and the app accepts HTTPS connections with invalid certificates.
