Description Andrej Nemec 2017-02-01 10:35:30 EST

The LocalClient.cmd_batch() method client does not accept external_auth credentials and so access to it from salt-api has been removed for now. This vulnerability allows code execution for already-authenticated users and is only in effect when running salt-api as the root user.

Created salt tracking bugs for this issue:

Affects: epel-all [bug 1418350]

Comment 2 Siddharth Sharma 2017-02-10 02:43:57 EST

Mitigation:

Disable salt-api for mitigation.

Comment 3 Siddharth Sharma 2017-02-10 02:48:32 EST

Statement:

This issue did not affect the versions of the salt as shipped with Red Hat Ceph Storage 1.3, Red Hat Ceph Storage 2, and Red Hat Storage Console 2 as salt-api and salt-ssh are not shipped with these products.
