Which versions of OpenStack Ironic are affected by CVE-2026-42510?

A command injection vulnerability (CVE-2026-42510, CVSS 7.2) in OpenStack Ironic's ipmitool integration could allow authenticated operators with high privileges to fully compromise bare-metal…. A patch is available.

How to fix or mitigate CVE-2026-42510?

Within 24 hours: Identify all OpenStack Ironic deployments at version 25.0.0 or earlier with console interfaces enabled and validate operator privilege separation controls. Within 7 days: Assess operational necessity of IPMI console functionality; if non-critical, disable ipmitool integration or restrict execution permissions to minimally-privileged operators only. Within 30 days: Monitor OpenStack security advisories for patched releases; prepare testing and deployment procedures in advance of vendor patch availability.

DescriptionNVD

OpenStack Ironic through 25.0.0 allows ipmitool execution in a non-default configuration that has a console interface.

AnalysisAI

Command injection via ipmitool in OpenStack Ironic through 25.0.0 allows authenticated operators with high privileges to trigger ipmitool execution when a console interface is configured in a non-default deployment, leading to high impact on confidentiality, integrity, and availability of the bare-metal provisioning node. No public exploit identified at time of analysis, EPSS is very low (0.07%, 20th percentile), and SSVC indicates no observed exploitation, consistent with a niche operator-level flaw rather than mass-scanning risk.

Technical ContextAI

OpenStack Ironic is the bare-metal provisioning service in OpenStack, used to manage physical hardware lifecycle via IPMI, Redfish and serial console drivers. The vulnerability is classed as CWE-829 (Inclusion of Functionality from an Untrusted Control Sphere), meaning Ironic invokes the external ipmitool binary in a code path reachable through the console interface when configured outside its default driver set. Because ipmitool runs with the privileges of the ironic-conductor process and can issue raw IPMI commands to managed BMCs, untrusted input flowing into its execution effectively bridges API-level operations into out-of-band hardware control. The affected component identified by CPE cpe:2.3:a:openstack:ironic:*:*:*:*:*:*:*:* covers all Ironic releases up to and including 25.0.0.

RemediationAI

Patch available per vendor advisory: upgrade Ironic to the fixed release referenced in OSSA-2026-008 (https://security.openstack.org/ossa/OSSA-2026-008.html); no exact fixed version is independently confirmed in the supplied data, so consult the advisory for the patched stable-branch release matching your OpenStack series. As a compensating control until patched, disable or unconfigure the console interface on ironic-conductor (set the affected console driver out of [DEFAULT]/enabled_console_interfaces or the equivalent in your driver composition) - the trade-off is loss of remote serial-console access to managed bare-metal nodes for operators. Additionally, tighten Keystone RBAC so that only a minimal set of trusted operator roles hold the high-privilege Ironic API rights needed to reach the vulnerable code path, and restrict network access to the Ironic API (typically port 6385) to management networks only.
