https://notcve.org/view.php?id=CVE-2022-3162
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 https://groups.google.com/g/kubernetes-security-announce/c/iUd550j7kjA https://security.netapp.com/advisory/ntap-20230511-0004 https://access.redhat.com/security/cve/CVE-2022-3162 https://bugzilla.redhat.com/show_bug.cgi?id=2136673 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-23: Relative Path Traversal •
CVSS: 3.5EPSS: 0%CPEs: 4EXPL: 0CVE-2020-8562 – Bypass of Kubernetes API Server proxy TOCTOU
https://notcve.org/view.php?id=CVE-2020-8562
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 actual connection. If a non-standard DNS server returns different non-cached responses, a user may be able to bypass the proxy IP restriction and access private networks on the control plane. Como mitigación a un informe de 2019 y CVE-2020-8555, Kubernetes intenta impedir que las conexiones proxy accedan a las redes link-local o localhost cuando son realizadas conexiones impulsadas por el usuario a los servicios, pods, nodos o proveedores de servicios StorageClass. • https://github.com/kubernetes/kubernetes/issues/101493 https://groups.google.com/g/kubernetes-security-announce/c/-MFX60_wdOY https://security.netapp.com/advisory/ntap-20220225-0002 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
