We are using chef 16 open source version and the openssl version which it is installing is coming as vulnerable with windows 2022. What can be the option to update openssl at msi level and keep running the same chef 16 with updated openssl version
There isn't any option to do that. You have to upgrade to latest infra-client version to get latest openssl. There were several fixes needed to chef code for openssl 3.x.
