CVE-2021-25736 2 Kubernetes, Microsoft 2 Kubernetes, Windows 2023-12-21 N/A 6.3 MEDIUM
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.
CVE-2020-8554 2 Kubernetes, Oracle 4 Kubernetes, Communications Cloud Native Core Network Slice Selection Function, Communications Cloud Native Core Policy and 1 more 2022-05-12 6.0 MEDIUM 5.0 MEDIUM
Kubernetes API server in all versions allow an attacker who is able to create a ClusterIP service and set the spec.externalIPs field, to intercept traffic to that IP address. Additionally, an attacker who is able to patch the status (which is considered a privileged operation and should not typically be granted to users) of a LoadBalancer service can set the status.loadBalancer.ingress.ip to similar effect.
CVE-2022-27652 4 Fedoraproject, Kubernetes, Mobyproject and 1 more 4 Fedora, Cri-o, Moby and 1 more 2022-04-27 4.6 MEDIUM 5.3 MEDIUM
A flaw was found in cri-o, where containers were incorrectly started with non-empty default permissions. A vulnerability was found in Moby (Docker Engine) where containers started incorrectly with non-empty inheritable Linux process capabilities. This flaw allows an attacker with access to programs with inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs.
CVE-2022-0532 2 Kubernetes, Redhat 2 Cri-o, Openshift Container Platform 2022-02-22 4.9 MEDIUM 4.2 MEDIUM
An incorrect sysctls validation vulnerability was found in CRI-O 1.18 and earlier. The sysctls from the list of "safe" sysctls specified for the cluster will be applied to the host if an attacker is able to create a pod with a hostIPC and hostNetwork kernel namespace.
CVE-2020-8561 1 Kubernetes 1 Kubernetes 2021-11-06 4.0 MEDIUM 4.1 MEDIUM
A security issue was discovered in Kubernetes where actors that control the responses of MutatingWebhookConfiguration or ValidatingWebhookConfiguration requests are able to redirect kube-apiserver requests to private networks of the apiserver. If that user can view kube-apiserver logs when the log level is set to 10, they can view the redirected responses and headers in the logs.

CVE-2019-11254 1 Kubernetes 1 Kubernetes 2020-10-02 4.0 MEDIUM 6.5 MEDIUM
The Kubernetes API Server component in versions 1.1-1.14, and versions prior to 1.15.10, 1.16.7 and 1.17.3 allows an authorized user who sends malicious YAML payloads to cause the kube-apiserver to consume excessive CPU cycles while parsing YAML.
CVE-2019-11249 2 Kubernetes, Redhat 2 Kubernetes, Openshift Container Platform 2020-10-02 5.8 MEDIUM 6.5 MEDIUM
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 of the local user. Kubernetes affected versions include versions prior to 1.13.9, versions prior to 1.14.5, versions prior to 1.15.2, and versions 1.1, 1.2, 1.4, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 1.10, 1.11, 1.12.

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.
CVE-2019-1002100 1 Kubernetes 1 Kubernetes 2020-08-24 4.0 MEDIUM 6.5 MEDIUM
In all Kubernetes versions prior to v1.11.8, v1.12.6, and v1.13.4, users that are authorized to make patch requests to the Kubernetes API Server can send a specially crafted patch of type "json-patch" (e.g. `kubectl patch --type json` or `"Content-Type: application/json-patch+json"`) that consumes excessive resources while processing, causing a Denial of Service on the API Server.
CVE-2020-8557 1 Kubernetes 1 Kubernetes 2020-08-21 2.1 LOW 5.5 MEDIUM
The Kubernetes kubelet component in versions 1.1-1.16.12, 1.17.0-1.17.8 and 1.18.0-1.18.5 do not account for disk usage by a pod which writes to its own /etc/hosts file. The /etc/hosts file mounted in a pod by kubelet is not included by the kubelet eviction manager when calculating ephemeral storage usage by a pod. If a pod writes a large amount of data to the /etc/hosts file, it could fill the storage space of the node and cause the node to fail.
CVE-2020-8559 1 Kubernetes 1 Kubernetes 2020-08-10 6.0 MEDIUM 6.8 MEDIUM
The Kubernetes kube-apiserver in versions v1.6-v1.15, and versions prior to v1.16.13, v1.17.9 and v1.18.6 are vulnerable to an unvalidated redirect on proxied upgrade requests that could allow an attacker to escalate privileges from a node compromise to a full cluster compromise.

A flaw was found in cri-o, as a result of all pod-related processes being placed in the same memory cgroup. This can result in container management (conmon) processes being killed if a workload process triggers an out-of-memory (OOM) condition for the cgroup. An attacker could abuse this flaw to get host network access on an cri-o host.
CVE-2019-1002101 2 Kubernetes, Redhat 2 Kubernetes, Openshift Container Platform 2020-02-10 5.8 MEDIUM 5.5 MEDIUM
The kubectl cp command allows copying files between containers and the user machine. To copy files from a container, Kubernetes creates a tar inside the container, 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 of the local user. The untar function can both create and follow symbolic links. The issue is resolved in kubectl v1.11.9, v1.12.7, v1.13.5, and v1.14.0.
CVE-2019-11251 1 Kubernetes 1 Kubernetes 2020-02-06 4.3 MEDIUM 5.7 MEDIUM
The Kubernetes kubectl cp command in versions 1.1-1.12, and versions prior to 1.13.11, 1.14.7, and 1.15.4 allows a combination of two symlinks provided by tar output of a malicious container to place a file outside of the destination directory specified in the kubectl cp invocation. This could be used to allow an attacker to place a nefarious file using a symlink, outside of the destination tree.
CVE-2018-1002104 1 Kubernetes 1 Nginx Ingress Controller 2020-01-17 5.0 MEDIUM 5.3 MEDIUM
Versions < 1.5 of the Kubernetes ingress default backend, which handles invalid ingress traffic, exposed prometheus metrics publicly.
CVE-2019-10223 3 Kubernetes, Linux, Redhat 3 Kube-state-metrics, Linux Kernel, Openshift Container Platform 2019-11-29 4.0 MEDIUM 6.5 MEDIUM
A security issue was discovered in the kube-state-metrics versions v1.7.0 and v1.7.1. An experimental feature was added to the v1.7.0 release that enabled annotations to be exposed as metrics. By default, the kube-state-metrics metrics only expose metadata about Secrets. However, a combination of the default `kubectl` behavior and this new feature can cause the entire secret content to end up in metric labels thus inadvertently exposing the secret content in metrics. This feature has been reverted and released as the v1.7.2 release. If you are running the v1.7.0 or v1.7.1 release, please upgrade to the v1.7.2 release as soon as possible.
CVE-2018-1002100 1 Kubernetes 1 Kubernetes 2019-10-09 3.6 LOW 5.5 MEDIUM
In Kubernetes versions 1.5.x, 1.6.x, 1.7.x, 1.8.x, and prior to version 1.9.6, the kubectl cp command insecurely handles tar data returned from the container, and can be caused to overwrite arbitrary local files.
CVE-2017-1002102 1 Kubernetes 1 Kubernetes 2019-10-09 6.3 MEDIUM 5.6 MEDIUM
In Kubernetes versions 1.3.x, 1.4.x, 1.5.x, 1.6.x and prior to versions 1.7.14, 1.8.9 and 1.9.4 containers using a secret, configMap, projected or downwardAPI volume can trigger deletion of arbitrary files/directories from the nodes where they are running.
CVE-2017-1002100 1 Kubernetes 1 Kubernetes 2017-09-29 4.0 MEDIUM 6.5 MEDIUM
Default access permissions for Persistent Volumes (PVs) created by the Kubernetes Azure cloud provider in versions 1.6.0 to 1.6.5 are set to "container" which exposes a URI that can be accessed without authentication on the public internet. Access to the URI string requires privileged access to the Kubernetes cluster or authenticated access to the Azure portal.
CVE-2015-7528 2 Kubernetes, Redhat 2 Kubernetes, Openshift 2016-06-15 5.0 MEDIUM 5.3 MEDIUM
Kubernetes before 1.2.0-alpha.5 allows remote attackers to read arbitrary pod logs via a container name.
