Security readout for executives and security teams
Plain-English summary
A flaw in OpenStack Ironic can permit ipmitool execution when a specific, non-default console interface is configured. Successful abuse could seriously affect confidentiality, integrity, and availability, but requires network access, high privileges, and high attack complexity. Most default deployments are not indicated as exposed.
Executive priority
Prioritize configuration-based triage. Remediate promptly where the non-default console interface and an affected release coexist; otherwise document the deployment as not exposed and monitor vendor guidance.
Technical view
CVE-2026-42510 affects Ironic releases before 35.0.1 under a non-default console configuration. The CVSS 3.1 score is 6.6: network-reachable, high complexity, high privileges required, no user interaction, unchanged scope, and high potential impact across confidentiality, integrity, and availability. It is classified as CWE-829.
Likely exposure
Exposure appears limited to deployments running an affected pre-35.0.1 release with the relevant non-default console interface. The structured affected entry names 4.3.0, 27.0.0, 30.0.0, and 33.0.0 while marking the default status unaffected. Confirm downstream package and branch status with vendor guidance.
Exploitation context
The supplied sources do not report active exploitation, and the CVE is not identified as KEV. Exploitation requires network access, high privileges, and high complexity, reducing broad opportunistic risk. Successful exploitation may nevertheless cause high confidentiality, integrity, and availability impact.
Researcher notes
The bundle establishes the version boundary, configuration dependency, CVSS vector, and CWE, but does not describe the precise execution path or publicly demonstrated exploit. The affected-version structure is narrower than the general pre-35.0.1 description, so branch-specific conclusions require the OpenStack advisory or distribution guidance.
Mitigation direction
- Consult OSSA-2026-008 and distribution guidance for applicable fixed packages or backports.
- Upgrade affected deployments to 35.0.1 or a vendor-confirmed fixed build.
- Pending upgrades, follow vendor guidance on disabling or replacing the affected non-default console configuration.
Validation and detection
- Inventory Ironic versions and compare them with 35.0.1 and vendor backport information.
- Inspect deployment configuration for the non-default console interface described by the advisory.
- Confirm upgraded packages or vendor backports are installed across every Ironic service instance.
- After remediation, verify expected console operations and review vendor-recommended security checks.
