MEDIUM 5.5DOWNGRADE

CVE-2022-1662 is a medium-severity flaw (CVSS 5.5) affecting convert2rhel. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

In convert2rhel, there's an ansible playbook named ansible/run-convert2rhel.yml which passes the Red Hat Subscription Manager user password via the CLI to convert2rhel. This could allow unauthorized local users to view the password via the process list while convert2rhel is running. However, this ansible playbook is only an example in the upstream repository and it is not shipped in officially supported versions of convert2rhel.
