CVE-2019-16252
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 · uneditedMissing SSL Certificate Validation in the Nutfind.com application through 3.9.12 for Android allows a man-in-the-middle attacker to sniff and manipulate all API requests, including login credentials and location data.
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 Nutfind.com Android application through version 3.9.12 fails to validate SSL certificates when establishing HTTPS connections, allowing attackers to perform man-in-the-middle attacks. This enables interception of all API traffic including user credentials and location data.

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 Nutfind app versionCheck the installed version of the Nutfind Android application on the device. On Android, this can be done via Settings > Apps > Nutfind, or by using ADB: adb shell dumpsys package com.nutfind.app (or the actual package name).Affected if The installed version is 3.9.12 or any version below 3.9.12.
-
Extract and inspect the app APKObtain the APK file from the device (using ADB: adb pull /data/app/com.nutfind.app/*.apk) and decompile it using tools like apktool or jadx to examine the source code.Affected if The APK is obtained and contains the vulnerable code.
-
Search for custom TrustManager implementationWithin the decompiled code, search for any custom TrustManager class implementations or instances where the default SSLContext is modified. Look for code that initializes an SSLContext with a custom TrustManager that performs no validation.Affected if A custom TrustManager is found that accepts all certificates or performs no certificate chain validation.
-
Inspect network security configurationCheck the app's AndroidManifest.xml and any network_security_config.xml for settings related to certificate validation. Look for debuggable network configurations or trust-anchors settings.Affected if The network security config disables certificate validation or allows user-added CAs without restriction.
If the Nutfind Android app version is 3.9.12 or lower AND the app code contains a custom TrustManager that bypasses certificate validation or has no certificate pinning, the environment is affected by this vulnerability.

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 certificate pinning or a properly configured TrustManager that verifies the server certificate chain.
