Resolution ========== Upgrade to 2019.2.4-1. # pacman -Syu "salt>=2019.2.4-1" The problems have been fixed upstream in version 2019.2.4. Workaround ========== Do not expose salt-master to the internet. Description =========== - CVE-2020-11651 (arbitrary command execution) 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 (arbitrary filesystem access) 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. Impact ====== A remote unauthenticated user can execute arbitrary commands and access files on the affected host.
