CVE-2020-28469
Description
A flaw was found in nodejs-glob-parent. The enclosure regex used to check for glob enclosures containing backslashes is vulnerable to Regular Expression Denial of Service attacks. This flaw allows an attacker to cause a denial of service if they can supply a malicious string to the glob-parent function. The highest threat from this vulnerability is to system availability.
Statement
While some components do package a vulnerable version of glob-parent, access to them requires OpenShift OAuth credentials and hence have been marked with a Low impact. This applies to the following products:
- OpenShift Container Platform (OCP)
- OpenShift ServiceMesh (OSSM)
- Red Hat Advanced Cluster Management for Kubernetes (RHACM)
- OpenShift distributed tracing
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).
