CVSS: 8.2EPSS: 85%CPEs: 50EXPL: 1CVE-2019-11248 – Kubernetes kubelet exposes /debug/pprof info on healthz port
https://notcve.org/view.php?id=CVE-2019-11248
29 Aug 2019 — The debugging endpoint /debug/pprof is exposed over the unauthenticated Kubelet healthz port. The go pprof endpoint is exposed over the Kubelet's healthz port. This debugging endpoint can potentially leak sensitive information such as internal Kubelet memory addresses and configuration, or for limited denial of service. Versions prior to 1.15.0, 1.14.4, 1.13.8, and 1.12.10 are affected. The issue is of medium severity, but not exposed by the default configuration. • https://github.com/bash3rt3am/poc-cve • CWE-419: Unprotected Primary Channel CWE-862: Missing Authorization •
CVSS: 8.1EPSS: 0%CPEs: 8EXPL: 0CVE-2019-11247 – Kubernetes kube-apiserver allows access to custom resources via wrong scope
https://notcve.org/view.php?id=CVE-2019-11247
15 Aug 2019 — The Kubernetes kube-apiserver mistakenly allows access to a cluster-scoped custom resource if the request is made as if the resource were namespaced. Authorizations for the resource accessed in this manner are enforced using roles and role bindings within the namespace, meaning that a user with access only to a resource in one namespace could create, view update or delete the cluster-scoped resource (according to their namespace role privileges). Kubernetes affected versions include versions prior to 1.13.9... • https://access.redhat.com/errata/RHBA-2019:2816 • CWE-20: Improper Input Validation CWE-284: Improper Access Control CWE-863: Incorrect Authorization •
CVSS: 6.5EPSS: 0%CPEs: 5EXPL: 0CVE-2019-11246 – kubectl cp allows symlink directory traversal
https://notcve.org/view.php?id=CVE-2019-11246
27 Jun 2019 — The kubectl cp command allows copying files between containers and the user machine. To copy files from a container, Kubernetes runs tar inside the container to create a tar archive, copies it over the network, and kubectl unpacks it on the user’s machine. If the tar binary in the container is malicious, it could run any code and output unexpected, malicious results. An attacker could use this to write files to any path on the user’s machine when kubectl cp is called, limited only by the system permissions ... • https://github.com/kubernetes/kubernetes/pull/76788 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-61: UNIX Symbolic Link (Symlink) Following •

https://notcve.org/view.php?id=CVE-2019-11244
22 Apr 2019 — In Kubernetes v1.8.x-v1.14.x, schema info is cached by kubectl in the location specified by --cache-dir (defaulting to $HOME/.kube/http-cache), written with world-writeable permissions (rw-rw-rw-). If --cache-dir is specified and pointed at a different location accessible to other users/groups, the written files may be modified by other users/groups and disrupt the kubectl invocation.

02 Apr 2019 — Cloud Native Computing Foundation (CNCF) CNI (Container Networking Interface) 0.7.4 has a network firewall misconfiguration which affects Kubernetes. The CNI 'portmap' plugin, used to setup HostPorts for CNI, inserts rules at the front of the iptables nat chains; which take precedence over the KUBE- SERVICES chain. Because of this, the HostPort/portmap rule could match incoming traffic even if there were better fitting, more specific service definition rules like NodePorts later in the chain.
