CVE-2016-4818
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 · uneditedDMMFX Trade for Android 1.5.0 and earlier, DMMFX DEMO Trade for Android 1.5.0 and earlier, and GAITAMEJAPAN FX Trade for Android 1.4.0 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 confidenceThree Android forex trading applications (DMMFX Trade, DMMFX DEMO Trade, and GAITAMEJAPAN FX Trade) fail to verify SSL certificates when establishing encrypted connections. This allows man-in-the-middle attackers to intercept sensitive financial data by presenting a fraudulent certificate, as the applications accept any certificate without validation.

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 version of DMMFX DEMO TradeOpen Android Settings > Apps > DMMFX DEMO Trade and view the version number under App info, or use adb shell dumpsys package dmm.dmmfx.demo.trade to retrieve versionInfoAffected if Version displayed is 1.5.0 or lower (the app accepts any SSL certificate without validation in these versions)
-
Identify installed version of DMMFX TradeOpen Android Settings > Apps > DMMFX Trade and view the version number under App info, or use adb shell dumpsys package dmm.dmmfx.trade to retrieve versionInfoAffected if Version displayed is 1.5.0 or lower (the app accepts any SSL certificate without validation in these versions)
-
Identify installed version of GAITAMEJAPAN FX TradeOpen Android Settings > Apps > GAITAMEJAPAN FX Trade and view the version number under App info, or use adb shell dumpsys package com.gaitamejapan.fx to retrieve versionInfoAffected if Version displayed is 1.4.0 or lower (the app accepts any SSL certificate without validation in these versions)
-
Confirm network traffic inspection vulnerabilityIf any of the three apps are installed in an affected version range, use a proxy tool like Burp Suite to intercept traffic from the app while it communicates with its trading server - the app will complete connections even with an untrusted or mismatched certificateAffected if The app successfully connects and transmits data when presented with an invalid or self-signed certificate, confirming SSL verification is disabled
You are affected if any of these three trading apps are installed on the device at versions at or below the affected thresholds (1.5.0 for DMMFX apps, 1.4.0 for GAITAMEJAPAN), as they do not validate SSL certificates and are vulnerable to man-in-the-middle interception of financial data.

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 using Android's CertificateChainCleaner and appropriate TrustManager configuration, or implement certificate pinning for the known trading server certificates.
