CVE-2026-46447 Details
Description
OpenStack Ironic before 35.0.2 allows Boot Script Injection of an iPXE script if the attacker can set node.driver_info or node.instance_info.
A boot script injection vulnerability has been identified in OpenStack Ironic versions 17.0.0 prior to 26.1.7, 27.0.0 prior to 29.0.6, 30.0.0 prior to 32.0.2, and 33.0.0 prior to 35.0.2. This vulnerability allows users with access to modify 'node.driver_info' or 'node.instance_info' to inject crafted values that execute iPXE scripts during the boot process. The issue arises from unsanitized user-controlled data in the kernel command line overrides, which can be exploited to redirect boot processes or access sensitive information.
Users can update to Ironic versions 2025.1, 2025.2, or 2026.1, where this vulnerability has been patched. For those using the 2024.1 or 2023.1 versions, which are unmaintained, no official patch is available, but the vulnerability can be manually addressed by removing control characters from the 'kernel_append_params' field.
