https://notcve.org/view.php?id=CVE-2021-25735
A security issue was discovered in kube-apiserver that could allow node updates to bypass a Validating Admission Webhook. Clusters are only affected by this vulnerability if they run a Validating Admission Webhook for Nodes that denies admission based at least partially on the old state of the Node object. Validating Admission Webhook does not observe some previous fields. Se ha detectado un problema de seguridad en kube-apiserver que podría permitir a las actualizaciones de los nodos omitir un Validating Admission Webhook. Los clusters sólo están afectados por esta vulnerabilidad si ejecutan un Validating Admission Webhook para nodos que deniega la admisión basándose, al menos parcialmente, en el estado antiguo del objeto Node. • https://github.com/darryk10/CVE-2021-25735 https://github.com/kubernetes/kubernetes/issues/100096 https://groups.google.com/g/kubernetes-security-announce/c/FKAGqT4jx9Y https://access.redhat.com/security/cve/CVE-2021-25735 https://bugzilla.redhat.com/show_bug.cgi?id=1937562 • CWE-20: Improper Input Validation CWE-372: Incomplete Internal State Distinction •
