1658394: CVE-2018-16879 Tower: security channel is not set properly for AMPQ connection
Tower does not set a secure channel as it is using the default insecure configuration channel settings for messaging celery workers from RabbitMQ. This could lead in data leak of sensitive information such as passwords as well as denial of service attacks by deleting projects or inventory files.

Find out more about CVE-2018-16879 from the MITRE CVE dictionary dictionary and NIST NVD.


Red Hat CloudForms versions 4.5 and 4.6 ship an ansible-tower which correctly sets the security channel by default. Red Hat CloudForms version 4.7 ships ansible-tower 3.3.3 which already contains the fix.
