Upgrade github.com/kubernetes/kubernetes to 1.25.4Upgrade github.com/kubernetes/kubernetes to 1.24.8Upgrade github.com/kubernetes/kubernetes to 1.23.14Upgrade github.com/kubernetes/kubernetes to 1.22.16Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for github.com/kubernetes/kubernetesHow to Check if You Are Affected
To determine whether your application is affected by CVE-2022-3294, inspect your project dependencies for Github.com/kubernetes/kubernetes:
inspect dependencies for github.com/kubernetes/kubernetesAnalyze the terminal output to locate any version of Github.com/kubernetes/kubernetes in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.25.4), your application is affected.
Note: Verify declared build manifests and deployed runtime container environments.

"details" : "Users may have access to secure endpoints in the control plane network. Kubernetes clusters are only affected if an untrusted user can modify Node objects and send proxy requests to them. Kubernetes supports node proxying, which allows clients of kube-apiserver to access endpoints of a Kubelet to establish connections to Pods, retrieve container logs, and more. While Kubernetes already validates the proxying address for Nodes, a bug in kube-apiserver made it possible to bypass this validation. Bypassing this validation could allow authenticated requests destined for Nodes to to the API server's private network.",
