## 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.
