CVE-2019-10747
Description
A flaw was found in nodejs-set-value. The function mixin-deep can be tricked into adding or modifying properties of Object.prototype using any of the constructor, prototype, or proto payloads. The highest threat from this vulnerability is to data confidentiality and integrity.
Statement
While OpenShift Container Platform (OCP) contains the affected nodejs-set-value code, it's added as a dependency of Kibana 5. Similar issue about prototype pollution [1] have been fixed, but no known attack vector was found, so we're rating this issue as Low for OCP.
In Red Hat Software Collections and Red Hat Enterprise Linux 8, nodejs-set-value is bundled into nodejs-nodemon, and is not meant to be accessed outside of that package. Within nodemon, this flaw is rated with a Low severity.
OpenShift distributed tracing bundles vulnerable version of Nodejs set-value package, however the components are protected by OpenShift OAuth, hence the impact by this vulnerability is reduced to LOW.

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).

Red Hat CVSS v3 Score Explanation
Prototype pollution relies on a user having the ability to merge new methods into an existing object. An attacker would have to know how those methods were going to be used by the application, so an attack is difficult to perform.
