Any project member with access to the default namespace can mount the netes-default service account in a pod, and then use that pod to execute administrative privileged commands against the k8s cluster. This could be mitigated by isolating the default namespace in a separate project, where only cluster admins can be given permissions to access. As of 2018-12-20, this bug affected ALL clusters created or imported by Rancher.","An issue was discovered in Rancher 2 through 2.1.5.

For example, a program may intend that private files can only be provided to a specific user. This effectively defines a control sphere that is intended to prevent attackers from accessing these private files. If the file permissions are insecure, then parties other than the user will be able to access those files.\nA separate control sphere might effectively require that the user can only access the private files, but not any other files on the system. If the program does not ensure that the user is only requesting private files, then the user might be able to access other files on the system.\nIn either case, the end result is that a resource has been exposed to the wrong party.","Draft","Class","Simple",false,[],{"title":72,"metaDescription":73,"keywords":74,"canonicalUrl":75,"structuredData":76},"What is CVE-2018-20321?
