CVE-2021-25736 – Windows kube-proxy LoadBalancer contention
https://notcve.org/view.php?id=CVE-2021-25736
Kube-proxy on Windows can unintentionally forward traffic to local processes listening on the same port (“spec.ports[*].port”) as a LoadBalancer Service when the LoadBalancer controller does not set the “status.loadBalancer.ingress[].ip” field. Clusters where the LoadBalancer controller sets the “status.loadBalancer.ingress[].ip” field are unaffected. Kube-proxy en Windows puede reenviar tráfico involuntariamente a procesos locales que escuchan en el mismo puerto (“spec.ports[*].port”) que LoadBalancer Service cuando el controlador LoadBalancer no configura “status.loadBalancer.ingress[].ip”. Los clústeres donde el controlador LoadBalancer establece el campo "status.loadBalancer.ingress[].ip" no se ven afectados. A flaw was found in the Windows kube-proxy component. • https://github.com/kubernetes/kubernetes/pull/99958 https://groups.google.com/g/kubernetes-security-announce/c/lIoOPObO51Q/m/O15LOazPAgAJ https://security.netapp.com/advisory/ntap-20231221-0003 https://access.redhat.com/security/cve/CVE-2021-25736 https://bugzilla.redhat.com/show_bug.cgi?id=1946538 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
