Salt 2019.2.4 Release Notes¶

Security Fix¶

CVE-2020-11651

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.

CVE-2020-11652

An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process ClearFuncs class allows access to some methods that improperly sanitize paths. These methods allow arbitrary directory access to authenticated users.

Known Issue¶

Part of the fix for CVE-2020-11651 added better validation of the methods allowed to be called by remote clients. Both AESFuncs and ClearFuncs now have an explicit list of methods that can be called. The name of one of these whitlisted methods on AESFuncs had a typo. The _minion_runner method should be minion_runner (without the underscore prefix). This typo breaks the publish module’s runner method. Calling runners, for example:

salt minion publish.runner manage.down

Will not work, and you will receive and empty reply from the salt master.

This will be addressed in the 3001 release of Salt set for mid-June 2020.
