CVE-2024-36536Public exploitNetwork attack vector

Cluster takeover via overprivileged service account token

Published Jul 24, 2024 · Updated Aug 2, 2024

Incorrect authorization in FabEdge 0.8.1 and earlier allows attackers to read Kubernetes secrets using a stolen service account token. FabEdge pods expose a service account token whose RBAC permissions let its bearer list cluster-wide secrets through the Kubernetes API. Exploitation requires control of a worker node or another ability to place a FabEdge pod on an attacker-controlled node; the token can then support cluster takeover.
