Summary
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.
