Comment 11 Nick Tait 2020-01-08 23:56:58 UTC
Mitigation:

This flaw can be mitigated by disabling the Web Management plugin: rabbitmq-plugins disable rabbitmq_management.

Comment 15 Summer Long 2020-01-09 04:27:09 UTC
Statement:

Red Hat Ansible Tower and Red Hat CloudForms are not vulnerable as they do not expose the RabbitMQ management interface by default. 
In Red Hat OpenStack Platform 13, the management interface was not enabled by default. So, although the flaw code was packaged, its impact for this version has been lowered to Moderate.
