Description Sam Fowler 2020-03-19 06:13:26 UTC

Versions before 1.5 of the Kubernetes NGINX Ingress Controller, exposed the prometheus '/metrics' endpoint publicly by default. A remote user could view cluster metrics without authenticating.

Upstream Issue:

https://github.com/kubernetes/ingress-nginx/pull/3125

Comment 1 Sam Fowler 2020-03-19 06:16:30 UTC

Statement:

OpenShift Container Platform is not affected by this flaw as it neither uses the Kubernetes NGINX Ingress Controller nor exposes exposes metrics publicly without authentication.
