AI risk analysis

Summary: The flaw allows authenticated users to inject shell metacharacters into command parameters, leading to arbitrary command execution with upgrade process privileges.
Exploitability: Exploitation requires user authentication and permission to create or update NodeUpgradeJob resources; moderate difficulty due to required permissions.
Blast radius: If exploited, it could compromise node confidentiality, integrity, and availability on edge devices.
Prioritized remediation: Update KubeEdge to version 1.21.2, 1.22.2, or 1.23.1 to mitigate the vulnerability.

NVD description

KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. From 1.12.0 until 1.21.2, 1.22.2, and 1.23.1, the v1alpha2 NodeUpgradeJob handler in edge/pkg/taskmanager/actions/nodeupgradejob.go concatenates authenticated user-controlled spec.version and spec.image values into the keadm upgrade edge shell command. A user with permission to create or update NodeUpgradeJob resources can supply shell metacharacters in either field, causing arbitrary commands to execute on targeted edge nodes with the privileges of the upgrade process and compromising node confidentiality, integrity, and availability. This issue is fixed in versions 1.21.2, 1.22.2, and 1.23.1.
