Directory traversal vulnerability in Kubernetes, as used in Red Hat OpenShift Enterprise 3.0, allows attackers to write to arbitrary files via a crafted object type name, which is not properly handled before passing it to etcd.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
