Description Yadnyawalk Tale 2020-07-17 12:15:09 UTC

Red Hat Satellite 6 allows local user of instance to read cache files. These credentials give full access via the API and local user on the foreman server can gain complete access of the instance.

Comment 2 Yadnyawalk Tale 2020-07-17 12:36:35 UTC

Mitigation:

This flaw can be mitigated by manually changing the directory permissions to remove readable bits for the others:
# chmod 0750 /run/foreman
