CVE-2022-2403Network attack vector

TLS private-key disclosure via readable ConfigMap

Published Sep 1, 2022 · Updated Aug 3, 2024

Information exposure in Red Hat OpenShift Container Platform 4.9 and later allows remote authenticated users to read a cluster TLS private key. The authentication-operator incorrectly stores the external cluster certificate's private key in oauth-serving-cert ConfigMaps where authenticated users and service accounts can read it. Cluster credentials are sufficient to obtain the key and compromise the confidentiality of web traffic protected by the certificate.
