Dependency: PR (#12065) needs to merge first.

Why I did it

os and commands modules are not secure against maliciously constructed input
getstatusoutput is detected without a static string, uses shell=True

How I did it

Eliminate the use of os and commands
Use subprocess instead

How to verify it

Which release branch to backport (provide reason below if selected)
