Описание
A flaw was found in Openshift. A pod with a DNSPolicy of "ClusterFirst" may incorrectly resolve the hostname based on a service provided. This flaw allows an attacker to supply an incorrect name with the DNS search policy, affecting confidentiality and availability.
Отчет
This is a known issue upstream: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/#namespaces-and-dns To guard against redirection attacks system administrators can pre-create the namespaces for TLDs or use a third-party solution to block users from creating those namespaces.
