I think you are mistaken, making the change I suggested
fixes the "TypeError: index() missing 1 required positional
argument" error you asked about.
Appended below is a runnable version of your code. I couldn't
tell from your post whether you just left out code after the
"if page !=..." statement for posting or whether is is acually
missing in your code. I filled what was need to run. Neither
the html in your code or the temple are referenced by the code
you posted so you'll need put the pieces together.

A subprocess should work if you run it with environment variables
set up the way web server would call it with. Alternatively
you could take the code in the cgi script (assuming its python)
and put it in a module function somewhere, then the cgi script
becomes a wrapper around a function call to it, and you can call
the same function in your flask code.
One last point: redirecting to an arbitrary page based on a url
provided by an untrusted user strikes me as dangerous. I would
at least whitelist the pages with something like:
if page not in ('products', 'about', help'): abort (404)
Hope this helps...
