An authenticated project manager can reparent Volume Connectors and Volume Targets to nodes in a different project, crossing project authorization boundaries and potentially exposing iSCSI secrets used for boot-from-volume configurations. However, exploitation requires the 'manager' role, which is not a default role in OpenStack and must be explicitly granted by an administrator. The attacker must also know the UUID of the target node in the other project. In Red Hat OpenStack Platform 18.0, the automatic_lessee feature defaults to false and did not function correctly; a properly working version was only introduced in upstream release 26.1.0 (gazpacho), which Red Hat does not ship. The parent/child node relationship capability, introduced in upstream Ironic 22.0.0, has never been shipped in any version of Red Hat OpenStack Platform or Red Hat OpenStack Services on OpenShift. These factors reduce the practical attack surface in Red Hat shipped configurations.", "threat_severity": "Important"}
