https://notcve.org/view.php?id=CVE-2020-8555
The Kubernetes kube-controller-manager in versions v1.0-1.14, versions prior to v1.15.12, v1.16.9, v1.17.5, and version v1.18.0 are vulnerable to a Server Side Request Forgery (SSRF) that allows certain authorized users to leak up to 500 bytes of arbitrary information from unprotected endpoints within the master's host network (such as link-local or loopback services). El Kubernetes kube-controller-manager en las versiones v1.0-1.14, versiones anteriores a v1.15.12, v1.16.9, v1.17.5 y v1.18.0, son vulnerables a un ataque de tipo Server Side Request Forgery (SSRF) que permite que determinados usuarios autorizados pierdan hasta 500 bytes de información arbitraria de endpoints desprotegidos dentro de la red host del maestro (tales como los servicios link-local o loopback) A server side request forgery (SSRF) flaw was found in Kubernetes. The kube-controller-manager allows authorized users with the ability to create StorageClasses or certain Volume types to leak up to 500 bytes of arbitrary information from the master's host network. This can include secrets from the kube-apiserver through the unauthenticated localhost port (if enabled). • http://www.openwall.com/lists/oss-security/2020/06/01/4 http://www.openwall.com/lists/oss-security/2021/05/04/8 https://github.com/kubernetes/kubernetes/issues/91542 https://groups.google.com/d/topic/kubernetes-security-announce/kEK27tqqs30/discussion https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3SOCLOPTSYABTE4CLTSPDIFE6ZZZR4LX https://security.netapp.com/advisory/ntap-20200724-0005 https://access.redhat.com/security/cve/CVE-2020-8555 https://bugzil • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-918: Server-Side Request Forgery (SSRF) •
