======================================================== OSSA-2026-025: RBAC Bypass in IPMI Raw Command Execution ========================================================
:Date: July 08, 2026 :CVE: CVE-2026-54423 Affects ~~~~~~~- Ironic: >=22.1.0 <29.0.6, >=30.0.0 <32.0.2, >=33.0.0 <35.0.2, >=36.0.0 <37.0.1
Description ~~~~~~~~~~~Dmitry Tantsur (Red Hat) and Tuomo Tanskanen (Ericsson Software Technology) of the Metal3.io Security Team descovered a vulnerability around IPMI management_interface. 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.
