I made a small website where people can upload their files into my server.
Every member have their own folder and they can't open or show other people directories.
Their links looks like this:
Members have an option to uploud php, java, html or any kind of file they want.
I made it like that because I want to give the ability for them to host a tiny website on my server, so for example if someone reach this link:
example.com/sub/mark/index.php It will open their home page. and anyone on internet can access that page, also no one can go back behind the main "sub" folder
I'm concerned about the security, "giving access to my server and let members upload any kind of file" what could go wrong? and how I can make it more secure?
