In OpenStack Ironic Python Agent through 11.6.0, a project-scoped user with the manager role can achieve arbitrary code execution on a running Ironic-Python-Agent via a maliciously constructed configuration, because the value of ntp_server is passed to a shell.

A vulnerability was found in Ironic-Python-Agent's (IPA) time syncing code. The value of the ntp_server configuration option is inserted into a shell command without sanitization. This command is run as root very early in the IPA startup flow, allowing an attacker to run arbitrary commands as root. This value can be set in three ways; directly in an operator-created ramdisk, set via kernel command line using Ironic, or passing the parameters via mDNS responder for mDNS enabled installation. For the most common, and highest security risk case, this means a Manager role associated with the project set as node.owner may be able to trigger this vulnerability.
