KubeEdge: ConfigUpdateJob updateFields enables remote shell injection and code execution on edge nodes

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

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.

## Description KubeEdge ConfigUpdateJob processing was vulnerable to command injection on edge nodes. The `updateFields` values from a ConfigUpdateJob were concatenated into a command string and executed through a system shell. An authenticated user with sufficient permissions to create or update ConfigUpdateJob resources could include shell metacharacters in the supplied configuration fields and cause unintended commands to be executed on targeted edge nodes. ## Impact Successful exploitation could allow an authenticated attacker to execute arbitrary commands on affected edge nodes with the privileges of the KubeEdge process handling the ConfigUpdateJob. The attacker must already have permission to create or modify ConfigUpdateJob resources and target an enrolled edge node. ## Patches The fix removes shell-based command construction and invokes `keadm config-update` using structured command arguments. The complete `--set` value is passed as a single literal argument, preventing shell metacharacters from being interpreted as commands. Fixes are planned for the following maintained releases: * v1.23.1 * v1.22.2 * v1.21.2 ## Workarounds Until a patched release is available: * restrict RBAC permissions for creating or modifying ConfigUpdateJob resources; * allow only trusted administrators to submit configuration update jobs; * avoid using ConfigUpdateJob in environments where its input cannot be fully trusted; * monitor ConfigUpdateJob resources and edge-node process activity for unexpected commands or changes. ## Credits KubeEdge thanks Sang-Hoon Choi ([KoreaSecurity](https://github.com/KoreaSecurity), Sejong University) for responsibly reporting this issue and for coordinating with the KubeEdge maintainers through the security disclosure process.
