CVE-2014-6020
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 Fuel Rewards Network (aka com.excentus.frn) application 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 Fuel Rewards Network Android application fails to validate X.509 certificates from SSL servers, allowing man-in-the-middle attackers to intercept and modify traffic by presenting arbitrary crafted certificates. The app essentially trusts all certificates, enabling attackers to spoof legitimate servers and capture sensitive information transmitted by the application.

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.
-
Identify installed app versionOpen Android Settings > Apps > Fuel Rewards Network and note the version number displayed, or use 'adb shell dumpsys package com.fuelrewards.network' to retrieve version infoAffected if Version is 1.0 exactly
-
Confirm SSL certificate validation is absentPerform dynamic analysis by configuring a proxy with an invalid/malicious certificate (e.g., using Burp Suite with a self-signed cert) and attempt to intercept traffic from the appAffected if App successfully establishes connections and transmits data despite presenting an untrusted/invalid certificate
-
Inspect certificate validation codeDecompile the APK (using apktool or jadx) and search for TrustManager implementations, hostname verification (HostnameVerifier), and check if custom TrustManagers accept all certificatesAffected if Code shows custom TrustManager that overrides checkServerTrusted() without proper chain validation, or TrustManager is left empty/unimplemented
Environment is affected if Fuel Rewards Network version 1.0 is installed and the app accepts invalid SSL certificates during network communication.

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 by ensuring the application verifies the certificate chain, validates hostname, and uses Android's default TrustManager or implements certificate pinning for added security.
