Command Injection in OpenStack Ironic IPMI Console Implementations

IdentifiersCVE-2026-42510CWE-77

CVE-2026-42510 is a command injection vulnerability in OpenStack Ironic's IPMI console implementations. In affected versions, a project manager associated with a node through the node.owner field can supply crafted input that is incorporated into ipmitool console execution, causing arbitrary commands to be executed by the Ironic conductor when the console is activated. The issue affects deployments that explicitly enabled the ipmitool-shellinabox or ipmitool-socat console interfaces; console backends are not enabled by default. Affected version ranges include 4.3.0 through before 26.1.6, 27.0.0 through before 29.0.5, 30.0.0 through before 32.0.1, and 33.0.0 through before 35.0.1.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows arbitrary command execution in the context of the Ironic conductor during console activation. This can enable compromise of the conductor host or service context, unauthorized manipulation of managed bare-metal infrastructure, access to sensitive operational data, and potential follow-on actions such as lateral movement or service disruption depending on conductor privileges and deployment architecture.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, disable the affected console interfaces by ensuring the conductor configuration does not enable ipmitool-shellinabox or ipmitool-socat. Because no console backends are enabled by default, reverting to the default state removes exposure. Security-sensitive operators should stop using the shellinabox-based console interface, which is already slated for removal due to broader security support concerns.

Remediation

Patch, then assume compromise.

Upgrade OpenStack Ironic to a fixed release. Reported fixed versions include 26.1.6, 29.0.5, 32.0.1, and 35.0.1 for the vulnerable branches. An additional follow-up correction was later required for certain ipmitool-socat deployments because an initial fix caused a console functionality regression without reintroducing the injection flaw; operators on affected branches should ensure they have the amended fix as provided by the vendor. For retired or unmaintained branches, apply the vendor-provided patch locally if no newer maintained release is available.
