CVE-2018-20200

Description

From CVE.org

CertificatePinner.java in OkHttp 3.x through 3.12.0 allows man-in-the-middle attackers to bypass certificate pinning by changing SSLContext and the boolean values while hooking the application. NOTE: This id is disputed because some parties don't consider this is a vulnerability. Their rationale can be found in https://github.com/square/okhttp/issues/4967

Statement

OkHttp is used by OpenShift Container Platform in the Aggregated Logging stack. This issue is not considered a vulnerability for OpenShift Container Platform as the prerequisite for exploitation is the ability to inject code into the application.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.
