A vulnerability was found in ironic-image up to 1.4.2. It has been declared as critical. Affected by this vulnerability is some unknown functionality. The manipulation with an unknown input leads to a missing authentication vulnerability. The CWE definition for the vulnerability is CWE-306. The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

ironic-image is a container image to run OpenStack Ironic as part of Metal³. Prior to version capm3-v1.4.3, if Ironic is not deployed with TLS and it does not have API and Conductor split into separate services, access to the API is not protected by any authentication. Ironic API is also listening in host network. In case the node is not behind a firewall, the API could be accessed by anyone via network without authentication. By default, Ironic API in Metal3 is protected by TLS and basic authentication, so this vulnerability requires operator to configure API without TLS for it to be vulnerable. TLS and authentication however should not be coupled as they are in versions prior to capm3-v1.4.3. A patch exists in versions capm3-v1.4.3 and newer. Some workarounds are available. Either configure TLS for Ironic API (`deploy.sh -t ...`, `IRONIC_TLS_SETUP=true`) or split Ironic API and Conductor via configuration change (old implementation, not recommended). With both workarounds, services are configured with httpd front-end, which has proper authentication configuration in place.

The weakness was presented 08/26/2023 as GHSA-jwpr-9fwh-m4g7. The advisory is shared at github.com. This vulnerability is known as CVE-2023-40585 since 08/16/2023. Neither technical details nor an exploit are publicly available.

Upgrading to version 1.4.3 eliminates this vulnerability. Applying the patch f64bb6ce0945bbfb30d9965f98149ea183311de9 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
