Medium [CVE-2026-54423] Arbitrary IPMI command execution via send_raw deployment step

In OpenStack Ironic before 37.0.1, an Ironic user with the ability to deploy nodes using the IPMI management interface can maliciously use the send_raw step to send arbitrary IPMI commands to a node, bypassing Ironic's access control.

IPMI send_raw capability is exposed multiple ways, including via VendorPassthru interfaces (restricted to system admin) and other step based flows such as cleaning or servicing. This also means any malicious user with the ability to initiate manual cleaning and servicing flows with arbitrary steps can also execute this vulnerability.

The Red Hat Product Security team has assessed the severity of this vulnerability as Moderate. 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.
