Description Guilherme de Almeida Suckevicz 2020-05-06 17:23:33 UTC
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.

Comment 1 Guilherme de Almeida Suckevicz 2020-05-06 17:23:56 UTC
Created salt tracking bugs for this issue:

Affects: epel-all [bug 1832475]
Affects: fedora-all [bug 1832476]

Comment 2 Hardik Vyas 2020-05-07 13:08:26 UTC
Statement:

Red Hat Ceph Storage 2 shipped salt for the usage of Red Hat Storage Console 2(RHSCON-2), which required salt to administrate ceph nodes. RHSCON-2 has reached End Of Life, hence salt is no longer used and supported. Therefore, the salt package provided by Red Hat Ceph Storage 2 has been marked as 'will not fix'.

Comment 4 Hardik Vyas 2020-05-07 13:08:32 UTC
Mitigation:

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
