CVE-2019-11243 is a vulnerability in Kubernetes
Published on April 22, 2019
In Kubernetes v1.12.0-v1.12.4 and v1.13.0, the rest.AnonymousClientConfig() method returns a copy of the provided config, with credentials removed (bearer token, username/password, and client certificate/key data). In the affected versions, rest.AnonymousClientConfig() did not effectively clear service account credentials loaded using rest.InClusterConfig()
Weakness Type
Privilege Dropping / Lowering Errors
The software does not drop privileges before passing control of a resource to an actor that does not have those privileges. In some contexts, a system executing with elevated permissions will hand off a process/file/etc. to another process or user. If the privileges of an entity are not reduced, then elevated privileges are spread throughout a system and possibly to an attacker.
