CVE-2022-24877: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
(updated )
Flux is an open and extensible continuous delivery solution for Kubernetes. Path Traversal in the kustomize-controller via a malicious kustomization.yaml
allows an attacker to expose sensitive data from the controller’s pod filesystem and possibly privilege escalation in multi-tenancy deployments. Workarounds include automated tooling in the user’s CI/CD pipeline to validate kustomization.yaml
files conform with specific policies. This vulnerability is fixed in kustomize-controller v0.24.0 and included in flux2 v0.29.0.
