CVE-2021-20238 1 Redhat 2 Openshift Container Platform, Openshift Machine-config-operator 2024-08-03 3.7 Low
It was found in OpenShift Container Platform 4 that ignition config, served by the Machine Config Server, can be accessed externally from clusters without authentication. The MCS endpoint (port 22623) provides ignition configuration used for bootstrapping Nodes and can include some sensitive data, e.g. registry pull secrets. There are two scenarios where this data can be accessed. The first is on Baremetal, OpenStack, Ovirt, Vsphere and KubeVirt deployments which do not have a separate internal API endpoint and allow access from outside the cluster to port 22623 from the standard OpenShift API Virtual IP address. The second is on cloud deployments when using unsupported network plugins, which do not create iptables rules that prevent to port 22623. In this scenario, the ignition config is exposed to all pods within the cluster and cannot be accessed externally.
CVE-2021-20288 4 Debian, Fedoraproject, Linuxfoundation and 1 more 4 Debian Linux, Fedora, Ceph and 1 more 2024-08-03 7.2 High
An authentication flaw was found in ceph in versions before 14.2.20. When the monitor handles CEPHX_GET_AUTH_SESSION_KEY requests, it doesn't sanitize other_keys, allowing key reuse. An attacker who can request a global_id can exploit the ability of any user to request a global_id previously associated with another user, as ceph does not force the reuse of old keys to generate new ones. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2021-20232 3 Fedoraproject, Gnu, Redhat 3 Fedora, Gnutls, Enterprise Linux 2024-08-03 9.8 Critical
