Title
Kanister has a potential risk which can be leveraged to make a cluster-level privilege escalation
Summary
Kanister is a data protection workflow management tool. The kanister has a deployment called default-kanister-operator, which is bound with a ClusterRole called edit via ClusterRoleBinding. The "edit" ClusterRole is one of Kubernetes default-created ClusterRole, and it has the create/patch/udpate verbs of daemonset resources, create verb of serviceaccount/token resources, and impersonate verb of serviceaccounts resources. A malicious user can leverage access the worker node which has this component to make a cluster-level privilege escalation.
