Discussion

Previous versions of software components that are not removed from the information system after updates have been installed may be exploited by adversaries. Some information technology products may remove older versions of software automatically from the information system.

Check Content

Confirm Nutanix AOS removes all software components after updated versions have been installed.

$ sudo grep -i clean_requirements_on_remove /etc/yum.conf
clean_requirements_on_remove=1

If "clean_requirements_on_remove" is not set to "1", "True", or "yes", or is not set in "/etc/yum.conf", this is a finding.

Fix Text

Configure Yum settings to remove all software components after an updated version is installed by running the following command:

$ sudo salt-call state.sls security/CVM/yumCVM
