While the IPMI send_raw functionality lacks a blocklist in certain step-based provisioning methods, exploitation requires privileges that are not available in default configurations. The SYSTEM_OR_OWNER_MEMBER_AND_LESSEE_ADMIN policy requires explicit administrator delegation of owner or lessee capabilities, and the automatic_lessee feature defaults to false and did not function correctly in shipped versions. This capability was introduced in upstream Ironic 22.1.0, which has not been shipped in any version of Red Hat OpenStack Platform or Red Hat OpenStack Services on OpenShift. In environments where exploitation is theoretically possible, an attacker could send arbitrary IPMI commands leading to unauthorized hardware control or system outage, but raw command access does not permit reading data returned by the BMC.", "threat_severity": "Moderate"}
