services / Azure / Kubernetes RoleBindings

Kubernetes RoleBindings in an AKS-managed aiManagers cluster, which bind RBAC Roles/ClusterRoles to subjects (users, groups, service accounts) and thereby determine who holds which in-cluster permissions.

RBAC bindings are the cluster's access-control policy; controlling them is equivalent to controlling who can do what, up to cluster-admin.

Creating/updating a RoleBinding binds an attacker-controlled subject to any role, directly granting elevated cluster permissions (the canonical privilege-escalation primitive).

Risks

Scope: CRITICAL

This privilege may grant access to sensitive data from a significant fraction of organizational functions, allow interruption of critical organizational services, or its exploit could lead to significant privilege escalation.
