## What is CVE-2017-3182?

CVE-2017-3182 is a medium-severity vulnerability in ThreatMetrix SDK, published on 24 Jul 2018. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

On 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.

Weakness: CWE-295 (Improper Certificate Validation)

Check this codebase for CVE-2017-3182 and fix it if it is affected.

What it is: CVE-2017-3182 is a medium-severity vulnerability in ThreatMetrix SDK, published on 24 Jul 2018. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2017-3182 in the wild and no public exploit code.

Affected product: ThreatMetrix SDK. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
