AI risk analysis

Summary: The flaw allows authenticated users to inject shell metacharacters into command execution, leading to arbitrary code execution with KubeEdge process privileges.
Exploitability: Exploitation requires user permissions to create or modify ConfigUpdateJob resources and knowledge of specific shell metacharacters; moderately difficult.
Blast radius: If exploited, could lead to full control over edge nodes enrolled in the KubeEdge system.
Prioritized remediation: Upgrade to KubeEdge versions 1.21.2, 1.22.2, or 1.23.1 immediately.

NVD description

KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. From 1.21.0 until 1.21.2, 1.22.2, and 1.23.1, ConfigUpdateJob processing in edge/pkg/taskmanager/actions/configupdatejob.go concatenates authenticated user-controlled updateFields values into the keadm config-update command and executes it through a system shell. A user with permission to create or modify ConfigUpdateJob resources can include shell metacharacters in the complete --set value and cause arbitrary commands to execute on an enrolled target edge node with the privileges of the KubeEdge process handling the job. This issue is fixed in versions 1.21.2, 1.22.2, and 1.23.1.
