A malicious user with access to deploy a node directly via Ironic can specify the IPMI send_raw deployment step with a malicious payload and send commands to that nodes’ BMC. IPMI send_raw capability is exposed multiple ways, including via our VendorPassthru interfaces (restricted to system admin) and other step based flows such as cleaning or servicing. This also means any malicious user with the ability to initate manual cleaning and servicing flows with arbitrary steps can also execute this vulnerability. Operators can fix this issue by applying the provided patches which apply a blocklist forbidding use of the IPMI send_raw functionality in certain provisioning methods. Clouds currently using IPMI send_raw functionality should carefully review the behavior changes in the provided patches to ensure their workflows are not broken.

This OSSA represents multiple related vulnerabilities in Ironic RBAC. An authenticated project manager can change the node associated with Volume Connectors or Volume Target objects, potentially changing the project permitted to access the object. Volume Connectors contain secrets in environments configuring boot from volume with iSCSI volumes. This is tracked as bug #2150256. Objects reparented in this manner cannot be detected via inspection of the data. Operators who are concerned they may have had this occur are encouraged to perform a basic audit of node configuration, for instance, insuring the expected number of volume targets, and volume connectors are present. Additionally, a project manager with the ability to create nodes can use the UUID of a node not owned by their project as a parent node when creating a new node. This mismatched child node can then be used to impact operations on the parent, such as forcing it to power on. This is tracked as bug #2150450. Ironic now specifically checks, and requires node parents and children to have matching node.owner values. This patch contains an enhancement to Ironic’s upgrade check to detect this mismatched state. Operators can use the provided ironic-status upgrade check to identify misconfigured nodes.

These patches also contain hardening logic to prevent this class of vulnerability in Port and Portgroup objects. This is a defense in depth measure to provide consistent errors at the API level for invalid data. Branch 2024.1/caracal is unmaintained and patches are provided as a courtesy. Bugfix branches will recieve patches in git but will not recieve a updated release. ========================================================= + CERT-RENATER | tel : 01-53-94-20-44 + + 23/25 Rue Daviel | fax : 01-53-94-20-41 + + 75013 Paris | email:cert@support.renater.fr + =========================================================
