Remediation
Red Hat statement
This issue did not affect the versions of the qpid -java broker as shipped with Red Hat MRG 2 and 3 and Satellite 6 as they did not use the access feature (e.g. Satellite 6 relies on client certificate authentication to control access).
Red Hat mitigation
If upgrading is not possible, the vulnerability can be mitigated using an ACL file containing "ACCESS VIRTUALHOST" clauses that white-lists user access to all virtualhosts. If AMQP 0-8, 0-9, 0-91, and 0-10 support is not required, the vulnerability can also be mitigated by turning off these protocols at the Port level.
