When specifying the plugin to load in the 'type' field in the network configuration, it is possible to use special elements such as \"../\" separators to reference binaries elsewhere on the system. This flaw allows an attacker to execute other existing binaries other than the cni plugins/types, such as 'reboot'. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability."
