## Remediation
Consider using AAD Pod Identity. A Microsoft project that allows scoping the identity of workloads to Kubernetes Pods instead of VMs (instances).
Starting in the 2020.10.15 Azure VHD Release, AKS restricts the pod CIDR access to that internal HTTP endpoint.

## Issue description
An attacker could view sensitive information about pods that are bound to a Node using the exposed /pods endpoint
This can be done either by accessing the readonly port (default 10255), or from the secure kubelet port (10250)
## Remediation
Ensure kubelet is protected using `--anonymous-auth=false` kubelet flag. Allow only legitimate users using `--client-ca-file` or `--authentication-token-webhook` kubelet flags. This is usually done by the installer or cloud provider.
Disable the readonly port by using `--read-only-port=0` kubelet flag.
