Magento Version exposure via Setup route with default Nginx Configuration

[SamJUK]

Preconditions and environment

Any Version of Magento using the Nginx sample config

Steps to reproduce

Navigate to https://site.com/setup/

Expected result

Return a 401/403 error, or at very minimum do not expose the exact version of Magento the site is running.

Actual result

We see a lovely page telling us exactly the Magento version is

Additional information

I believe in 2.4, the web based setup was removed. Although the page is still accessible displaying the Magento Version.

Typically those using the default Nginx configuration are less technical / security focused. And they trust the default provided Nginx configure is secure by default. I would argue exposing the exact Magento package version provides no benefit whilst telling potential bad actors exactly what exploits to attempt or search for.
