Upload folder can be accessible

Hello, this is my first post.
As I went to System Admin this message appeared in red:
The system check has detected that your uploads folder may be publicly accessible. This suggests a serious issue in your server configuration that should be addressed immediately. Please visit our Post-Install and Server Config page for instructions to fix this issue.

After clicking that link, I went to passage saying about Upload folder. As if it only speaks about one specific situation on Apache2.
My server (I access it from CPanel) doesn’t seem to fit description and solution given there.

I tried to find files mentioned in the text but I failed.

Seriously I am just starting but it seem to overcome me already.

Would you have an idea where to start to solve it?
