CVSS: 9.0EPSS: 0%CPEs: 4EXPL: 0CVE-2022-3294 – Node address isn't always verified when proxying
https://notcve.org/view.php?id=CVE-2022-3294
01 Mar 2023 — Users may have access to secure endpoints in the control plane network. Kubernetes clusters are only affected if an untrusted user can modify Node objects and send proxy requests to them. Kubernetes supports node proxying, which allows clients of kube-apiserver to access endpoints of a Kubelet to establish connections to Pods, retrieve container logs, and more. While Kubernetes already validates the proxying address for Nodes, a bug in kube-apiserver made it possible to bypass this validation. Bypassing thi... • https://github.com/kubernetes/kubernetes/issues/113757 • CWE-20: Improper Input Validation •

18 Jan 2023 — Users authorized to list or watch one type of namespaced custom resource cluster-wide can read custom resources of a different type in the same API group without authorization. Clusters are impacted by this vulnerability if all of the following are true: 1. There are 2+ CustomResourceDefinitions sharing the same API group 2. Users have cluster-wide list or watch authorization on one of those custom resources. 3. The same users are not authorized to read another custom resource in the same API group. • https://github.com/kubernetes/kubernetes/issues/113756 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-23: Relative Path Traversal •

https://notcve.org/view.php?id=CVE-2020-8562
01 Feb 2022 — As mitigations to a report from 2019 and CVE-2020-8555, Kubernetes attempts to prevent proxied connections from accessing link-local or localhost networks when making user-driven connections to Services, Pods, Nodes, or StorageClass service providers. As part of this mitigation Kubernetes does a DNS name resolution check and validates that response IPs are not in the link-local (169.254.0.0/16) or localhost (127.0.0.0/8) range. Kubernetes then performs a second DNS resolution without validation for the actu... • https://github.com/kubernetes/kubernetes/issues/101493 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
