The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2020:2480 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):
* cfme-gemset: rubygem-rack: hijack sessions by using timing attacks targeting the session id (CVE-2019-16782)
* cfme-amazon-smartstate: rubygem-rack: hijack sessions by using timing attacks targeting the session id (CVE-2019-16782)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Additional Changes:
This update fixes various bugs and adds enhancements. Documentation for these changes is available from the Release Notes document linked to in the References section.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
