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 TripAdvisor app 6.6 for iOS sends cleartext credentials, which allows remote attackers to obtain sensitive information by sniffing the network.

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 · moderate confidence

The TripAdvisor iOS app version 6.6 transmits user credentials in cleartext over the network, without TLS/SSL encryption. This allows any attacker on the same network to intercept and read the credentials using packet sniffing tools.

MitigationImplement TLS/SSL encryption for all authentication-related network communications and ensure proper certificate validation to prevent man-in-the-middle attacks.

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 TripAdvisor iOS app version
    Open the App Store app, go to the Updates tab, find TripAdvisor in your purchased apps or installed apps list, and view the version number. Alternatively, open TripAdvisor app, go to Settings > About to view the version.
    Affected if The displayed version number is exactly 6.6
  2. Confirm app is the original TripAdvisor app
    Verify the app is the official TripAdvisor app from TripAdvisor Inc, not a third-party alternative. Check the developer name in the App Store listing or the app's bundle identifier.
    Affected if The app is the official TripAdvisor app version 6.6 from TripAdvisor Inc
  3. Verify network transmission method
    Since this is a legacy CVE from 2012, you would need to capture network traffic from the device using a network proxy or packet sniffing tool to observe if login credentials are transmitted without TLS encryption. However, given the version-specific nature of this CVE, version 6.6 is the primary indicator.
    Affected if Running TripAdvisor iOS app version 6.6, which historically transmitted credentials in cleartext

You are affected if the TripAdvisor iOS app installed on your device is version 6.6 from TripAdvisor Inc.
