Redhat: >> Advanced Cluster Management For Kubernetes Security Vulnerabilities
A container privilege escalation flaw was found in certain Multicluster Engine for Kubernetes images. This issue stems from the /etc/passwd file being created with group-writable permissions during build time. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, can leverage their membership in the root group to modify the /etc/passwd file. This could allow the attacker to add a new user with any arbitrary UID, including UID 0, leading to full root privileges within the container.

A flaw was found in Open Cluster Management (OCM), the technology underlying Red Hat Advanced Cluster Management (ACM). Improper validation of Kubernetes client certificate renewal allows a managed cluster administrator to forge a client certificate that can be approved by the OCM controller. This enables cross-cluster privilege escalation and may allow an attacker to gain control over other managed clusters, including the hub cluster.

A flaw was found in Red Hat Advanced Cluster Management through versions 2.10, before 2.10.7, 2.11, before 2.11.4, and 2.12, before 2.12.4. This vulnerability allows an unprivileged user to view confidential managed cluster credentials through the UI. This information should only be accessible to authorized users and may result in the loss of confidentiality of administrative information, which could be leaked to unauthorized actors.

The grc-policy-propagator allows security escalation within the cluster. The propagator allows policies which contain some dynamically obtained values (instead of the policy apply a static manifest on a managed cluster) of taking advantage of cluster scoped access in a created policy. This feature does not restrict properly to lookup content from the namespace where the policy was created.

RHACM: unauthenticated SSRF in console API endpoint. A Server-Side Request Forgery (SSRF) vulnerability was found in the console API endpoint from Red Hat Advanced Cluster Management for Kubernetes (RHACM). An attacker could take advantage of this as the console API endpoint is missing an authentication check, allowing unauthenticated users making requests.
