Affected: Ubuntu:Pro:14.04:LTS: salt, Ubuntu:16.04:LTS: salt, Ubuntu:18.04:LTS: salt

An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process ClearFuncs class does not properly validate method calls. This allows a remote user to access some methods without authentication. These methods can be used to retrieve user tokens from the salt master and/or run arbitrary commands on salt minions.
