CVE-2017-3182
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 · uneditedOn the iOS platform, the ThreatMetrix SDK versions prior to 3.2 fail to validate SSL certificates provided by HTTPS connections, which may allow an attacker to perform a man-in-the-middle (MITM) attack. ThreatMetrix is a security library for mobile applications, which aims to provide fraud prevention and device identity capabilities. The ThreatMetrix SDK versions prior to 3.2 do not validate SSL certificates on the iOS platform. An affected application will communicate with https://h-sdk.online-metrix.net, regardless of whether the connection is secure or not. An attacker on the same network as or upstream from the iOS device may be able to view or modify ThreatMetrix network traffic that should have been protected by HTTPS.
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 ThreatMetrix SDK for iOS versions prior to 3.2 fail to validate SSL certificates during HTTPS connections to h-sdk.online-metrix.net, allowing attackers to perform MITM attacks and view or modify supposedly encrypted traffic.

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 ThreatMetrix SDK presenceInspect the iOS application's embedded frameworks, libraries, or dependency files (such as Podfile, Package.swift, or Cartfile) to determine if the ThreatMetrix SDK is included in the buildAffected if ThreatMetrix SDK is found in the application dependencies or frameworks
-
Determine the installed SDK versionLocate the ThreatMetrix SDK version identifier within the application bundle or dependency manifest file (check framework binary, Podfile.lock, or embedded dylib version strings)Affected if The SDK version is below 3.2 (e.g., 3.1.x, 3.0.x, etc.)
-
Verify network endpoint connectivityUse a network proxy or traffic inspection tool to monitor if the application establishes HTTPS connections to h-sdk.online-metrix.netAffected if The application sends traffic to h-sdk.online-metrix.net
-
Confirm SSL validation is bypassedPerform a MITM proxy test (e.g., using Burp Suite or Charles Proxy) with a self-signed certificate and observe if the application accepts the invalid certificate without rejectionAffected if The application accepts invalid or untrusted SSL certificates when connecting to h-sdk.online-metrix.net, indicating certificate validation is not occurring
The environment is affected if the ThreatMetrix SDK for iOS with a version lower than 3.2 is present and the application connects to h-sdk.online-metrix.net with certificate validation disabled.

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 data3.2
Update the ThreatMetrix SDK to version 3.2 or later which includes proper SSL certificate validation.
