CVSS: 4.9EPSS: 0%CPEs: 4EXPL: 0CVE-2021-25737 – Holes in EndpointSlice Validation Enable Host Network Hijack
https://notcve.org/view.php?id=CVE-2021-25737
A security issue was discovered in Kubernetes where a user may be able to redirect pod traffic to private networks on a Node. Kubernetes already prevents creation of Endpoint IPs in the localhost or link-local range, but the same validation was not performed on EndpointSlice IPs. Se ha detectado un problema de seguridad en Kubernetes en el que un usuario puede ser capaz de redirigir el tráfico del pod a redes privadas en un Nodo. Kubernetes ya previene la creación de IPs de Endpoint en el rango localhost o link-local, pero no se ha llevado a cabo la misma comprobación en las IPs de EndpointSlice. A security issue was discovered in Kubernetes where an authorized user may be able to redirect traffic to private networks on a Node. • https://github.com/kubernetes/kubernetes/issues/102106 https://groups.google.com/g/kubernetes-security-announce/c/xAiN3924thY https://security.netapp.com/advisory/ntap-20211004-0004 https://access.redhat.com/security/cve/CVE-2021-25737 https://bugzilla.redhat.com/show_bug.cgi?id=1954917 • CWE-20: Improper Input Validation CWE-184: Incomplete List of Disallowed Inputs CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
CVSS: 6.3EPSS: 0%CPEs: 4EXPL: 0CVE-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 •
