The version of cri-o as released for Red Hat OpenShift Container Platform 4.9.48, 4.10.31, and 4.11.6 via RHBA-2022:6316, RHBA-2022:6257, and RHBA-2022:6658, respectively, included an incorrect version of cri-o missing the fix for CVE-2022-27652, which was previously fixed in OCP 4.9.41 and 4.10.12 via RHBA-2022:5433 and RHSA-2022:1600. This issue could allow an attacker with access to programs with inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs. For more details, see https://access.redhat.com/security/cve/CVE-2022-27652.

A compliance problem was found in the Red Hat OpenShift Container Platform. Red Hat discovered that, when FIPS mode was enabled, not all of the cryptographic modules in use were FIPS-validated.

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.

In OpenShift Container Platform, a user with permissions to create or modify Routes can craft a payload that inserts a malformed entry into one of the cluster router's HAProxy configuration files. This malformed entry can match any arbitrary hostname, or all hostnames in the cluster, and direct traffic to an arbitrary application within the cluster, including one under attacker control.

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.

A flaw was found in the Restricted Security Context Constraints (SCC), where it allows pods to craft custom network packets. This flaw allows an attacker to cause a denial of service attack on an OpenShift Container Platform cluster if they can deploy pods. The highest threat from this vulnerability is to system availability.

It was discovered that OpenShift Container Platform's (OCP) distribution of Kibana could open in an iframe, which made it possible to intercept and manipulate requests. This flaw allows an attacker to trick a user into performing arbitrary actions in OCP's distribution of Kibana, such as clickjacking.

A malicious container image can consume an unbounded amount of memory when being pulled to a container runtime host, such as Red Hat Enterprise Linux using podman, or OpenShift Container Platform. An attacker can use this flaw to trick a user, with privileges to pull container images, into crashing the process responsible for pulling the image. This flaw affects containers-image versions before 5.2.0.

A flaw was found in atomic-openshift of openshift-4.2 where the basic-user RABC role in OpenShift Container Platform doesn't sufficiently protect the GlusterFS StorageClass against leaking of the restuserkey. An attacker with basic-user permissions is able to obtain the value of restuserkey, and use it to authenticate to the GlusterFS REST service, gaining access to read, and modify files.

A flaw was discovered in OpenShift Container Platform 4 where, by default, users with access to create pods also have the ability to schedule workloads on master nodes. Pods with permission to access the host network, running on master nodes, can retrieve security credentials for the master AWS IAM role, allowing management access to AWS resources. With access to the security credentials, the user then has access to the entire infrastructure. Impact to data and system availability is high.

A flaw was found in the OpenShift Installer before version v0.9.0-master.0.20210125200451-95101da940b0. During installation of OpenShift Container Platform 4 clusters, bootstrap nodes are provisioned with anonymous authentication enabled on kubelet port 10250. A remote attacker able to reach this port during installation can make unauthenticated `/exec` requests to execute arbitrary commands within running containers. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A flaw was found in OpenShift Container Platform where OAuth tokens are not encrypted when the encryption of data at rest is enabled. This flaw allows an attacker with access to a backup to obtain OAuth tokens and then use them to log into the cluster as any user who logged into the cluster via the WebUI or via the command line in the last 24 hours. Once the backup is older than 24 hours the OAuth tokens are no longer valid.

A flaw was found in openshift-ansible. OpenShift Container Platform (OCP) 3.11 is too permissive in the way it specified CORS allowed origins during installation. An attacker, able to man-in-the-middle the connection between the user's browser and the openshift console, could use this flaw to perform a phishing attack. The main threat from this vulnerability is data confidentiality.

A flaw was found in OpenShift Container Platform version 4.1 and later. Sensitive information was found to be logged by the image registry operator allowing an attacker able to gain access to those logs, to read and write to the storage backing the internal image registry. The highest threat from this vulnerability is to data integrity.

A flaw was found during the upgrade of an existing OpenShift Container Platform 3.x cluster. Using CRI-O, the dockergc service account is assigned to the current namespace of the user performing the upgrade. This flaw can allow an unprivileged user to escalate their privileges to those allowed by the privileged Security Context Constraints.

OpenShift Container Platform 4 does not sanitize secret data written to static pod logs when the log level in a given operator is set to Debug or higher. A low privileged user could read pod logs to discover secret material if the log level has already been modified in an operator by a privileged user.

OpenShift Container Platform, versions 4.1 and 4.2, does not sanitize secret data written to pod logs when the log level in a given operator is set to Debug or higher. A low privileged user could read pod logs to discover secret material if the log level has already been modified in an operator by a privileged user.

The containers/image library used by the container tools Podman, Buildah, and Skopeo in Red Hat Enterprise Linux version 8 and CRI-O in OpenShift Container Platform, does not enforce TLS connections to the container registry authorization service. An attacker could use this vulnerability to launch a MiTM attack and steal login credentials or bearer tokens.

A flaw was found in OpenShift Container Platform, versions 3.11 and later, in which the CSRF tokens used in the cluster console component were found to remain static during a user's session. An attacker with the ability to observe the value of this token would be able to re-use the token to perform a CSRF attack.

OpenShift Container Platform before version 4.1.3 writes OAuth tokens in plaintext to the audit logs for the Kubernetes API server and OpenShift API server. A user with sufficient privileges could recover OAuth tokens from these audit logs and use them to access other resources.
