Privilege Escalation in Kubernetes

In all Kubernetes versions prior to v1.10.11, v1.11.5, and v1.12.3, incorrect handling of error responses to proxied upgrade requests in the kube-apiserver allowed specially crafted requests to establish a connection through the Kubernetes API server to backend servers, then send arbitrary reques...

Cryptographic Issues in ECK

Elastic Cloud on Kubernetes ECK versions prior to 1.1.0 generate passwords using a weak random number generator. If an attacker is able to determine when the current Elastic Stack cluster was deployed they may be able to more easily brute force the Elasticsearch credentials generated by ECK...

GHSA-JP32-VMM6-3VF5 Directory Traversal in Kubernetes

Directory traversal vulnerability in Kubernetes, as used in Red Hat OpenShift Enterprise 3.0, allows attackers to write to arbitrary files via a crafted object type name, which is not properly handled before passing it to etcd...

GHSA-HWRR-RHMM-VCVF NULL Pointer Dereference in Kubernetes CSI snapshot-controller

Kubernetes CSI snapshot-controller prior to v2.1.3 and v3.0.2 could panic when processing a VolumeSnapshot custom resource when: - The VolumeSnapshot referenced a non-existing PersistentVolumeClaim and the VolumeSnapshot did not reference any VolumeSnapshotClass. - The snapshot-controller crashes...

Allocation of Resources Without Limits or Throttling and Uncontrolled Memory Allocation in Kubernetes

The Kubelet component in versions 1.15.0-1.15.9, 1.16.0-1.16.6, and 1.17.0-1.17.2 has been found to be vulnerable to a denial of service attack via the kubelet API, including the unauthenticated HTTP read-only API typically served on port 10255, and the authenticated HTTPS API typically served on...

Directory traversal in Kubernetes Secrets Store CSI Driver

Kubernetes Secrets Store CSI Driver versions v0.0.15 and v0.0.16 allow an attacker who can modify a SecretProviderClassPodStatus/Status resource the ability to write content to the host filesystem and sync file contents to Kubernetes Secrets. This includes paths under var/lib/kubelet/pods that...

Kubernetes Arbitrary Command Injection

In Kubernetes versions 1.9.0-1.9.9, 1.10.0-1.10.5, and 1.11.0-1.11.1, user input was handled insecurely while setting up volume mounts on Windows nodes, which could lead to command line argument injection. Specific Go Packages Affected k8s.io/kubernetes/pkg/util/mount...

GO-2022-0701 Directory traversal in k8s.io/kubernetes

Crafted object type names can cause directory traversal in Kubernetes. Object names are not validated before being passed to etcd. This allows attackers to write arbitrary files via a crafted object name, hence causing directory traversal vulnerability in Kubernetes, as used in Red Hat OpenShift...

GHSA-82HX-W2R5-C2WQ Kubernetes API Server DoS Via API Requests

The Kubernetes API server component in Kubernetes versions prior to 1.15.9, 1.16.0-1.16.6, and 1.17.0-1.17.2 has been found to be vulnerable to a denial of service attack via successful API requests...

GHSA-2575-PGHM-6QQX Kubernetes Unsafe Cacheing

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...

GHSA-XX8C-M748-XR4J Access Restriction Bypass in kubernetes

The API server in Kubernetes does not properly check admission control, which allows remote authenticated users to access additional resources via a crafted patched object. Specific Go Packages Affected github.com/kubernetes/kubernetes/pkg/apiserver...

GHSA-5CGX-VHFP-6CF9 Directory traversal in Kubernetes Secrets Store CSI Driver

Kubernetes Secrets Store CSI Driver versions v0.0.15 and v0.0.16 allow an attacker who can modify a SecretProviderClassPodStatus/Status resource the ability to write content to the host filesystem and sync file contents to Kubernetes Secrets. This includes paths under var/lib/kubelet/pods that...

GO-2022-0629 Directory traversal in sigs.k8s.io/secrets-store-csi-driver

Modifying pod status allows host directory traversal. Kubernetes Secrets Store CSI Driver allows an attacker who can modify a SecretProviderClassPodStatus/Status resource the ability to write content to the host filesystem and sync file contents to Kubernetes Secrets. This includes paths under...

Improper Authentication in Kubernetes

A security issue was discovered in the Kubelet and kube-proxy components of Kubernetes which allows adjacent hosts to reach TCP and UDP services bound to 127.0.0.1 running on the node or in the node's network namespace. For example, if a cluster administrator runs a TCP service on a node that...
