Vulnerability in Red Hat Openshift
CVE-2022-2403
A credentials leak was found in the OpenShift Container Platform. The private key for the external cluster certificate was stored incorrectly in the oauth-serving-cert ConfigMaps, and accessible to any authenticated OpenShift user or service-account. A malicious user could exploit this flaw by reading the oauth-serving-cert ConfigMap in the openshift-config-managed namespace, compromising any web traffic secured using that certificate.
