Description Andrej Nemec 2017-02-01 15:35:30 UTC

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.

Comment 1 Andrej Nemec 2017-02-01 15:41:58 UTC

Created salt tracking bugs for this issue:

Comment 2 Siddharth Sharma 2017-02-10 07:43:57 UTC

Mitigation:

Disable salt-api for mitigation.

Comment 3 Siddharth Sharma 2017-02-10 07:48:32 UTC

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.
