When running Tower before 3.4.3 on OpenShift or Kubernetes, application credentials are exposed to playbook job runs via environment variables. A malicious user with the ability to write playbooks could use this to gain administrative privileges.

The version of Ansible Tower running on the remote web server is 3.3.x prior to 3.3.5 or 3.4.x prior to 3.4.3. It is, therefore, affected by a anauthorized access vulnerability due to a RabbitMQ misconfiguration.  The configuration does not set a secure channel for messaging celery workers, resulting in a leak of sensitive data, resulting in a potential privilege escalation vulnerability, as well as the ability to delete projects & files.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:0796 advisory.

    Red Hat CloudForms Management Engine delivers the insight, control, and automation needed to address the     challenges of managing virtual environments. CloudForms Management Engine is built on Ruby on Rails, a     model-view-controller (MVC) framework for web application development. Action Pack implements the     controller and the view components.

    Security Fix(es):

    * rubygem-actionpack: render file directory traversal in Action View (CVE-2019-5418)

    * rubygem-actionpack: denial of service vulnerability in Action View (CVE-2019-5419)
