CVE-2026-54423 · Severity: high · CVSS 8.2 · Published 2026-07-10

OpenStack Ironic is a service used to manage and provision physical hardware (bare metal) servers. A security flaw allows users with permission to deploy or maintain servers to bypass safety controls and send raw, low-level commands directly to a server's hardware management controller (BMC). This could allow an attacker to gain persistent access to the hardware, modify network settings, or disrupt the server's availability.

## Technical details

A vulnerability in OpenStack Ironic's IPMI management interface allows users with the ability to initiate deployment, cleaning, or servicing flows to execute arbitrary IPMI commands. The 'send_raw' step, located in the ipmitool driver, was registered as a valid step for deployment and maintenance without sufficient RBAC distinction. While administrative interfaces like VendorPassthru are restricted, this flaw allows a project member with 'set_provision_state' permissions to include malicious IPMI payloads in manual cleaning or service steps. An attacker can use this to modify BMC users, alter network configurations, or ensure persistent out-of-band access. The issue is addressed in version 37.0.1 and various backported patches by implementing a blocklist for the send_raw functionality in specific provisioning methods.
