CVE-2014-5857
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 · uneditedThe White & Yellow Pages (aka com.avantar.wny) application 5.1.1 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 confidenceThe White & Yellow Pages Android application version 5.1.1 fails to validate X.509 certificates from SSL servers. This allows an attacker positioned on the same network to intercept and modify SSL/TLS traffic by presenting a forged certificate, effectively performing a man-in-the-middle attack to steal sensitive data transmitted by the app.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify the installed White & Yellow Pages app versionOn the Android device, go to Settings > Apps > White & Yellow Pages (or Avantar) and check the version number under App Info. Alternatively, use ADB with command: `adb shell dumpsys package com.avantar.yellowpages` (or the actual package name) to retrieve versionInfo.Affected if The installed version is exactly 5.1.1, as this is the only version affected by this CVE.
-
Confirm the app transmits data over networkMonitor network traffic while using the app. Use a packet capture tool on the device or check if the app has network permissions in its manifest (look for INTERNET permission).Affected if The app makes outbound network connections, as the vulnerability allows interception of this traffic through SSL/TLS.
-
Determine if the app handles sensitive dataReview the app functionality. The vulnerability description indicates the app transmits sensitive data that could be stolen via MITM attacks.Affected if The app is used to transmit login credentials, personal information, or other sensitive data over the network, as this data would be at risk if intercepted.
A user is affected if they have installed White & Yellow Pages version 5.1.1 on their Android device and use the app to transmit sensitive data over network connections, making them vulnerable to man-in-the-middle attacks on the same network.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper SSL certificate validation in the Android application using certificate chain verification, hostname validation, and potentially certificate pinning for high-security endpoints.
