Let's say example1.com is located in US, and example2.com is located in EU.
example1.com/folder/ has 777 permission.
Will a script in example2.com be able to write on
Or is the 777 permission only applicable to other users in example1.com server and users in the "outside" world has no access to it?
To those asking more details:
US server has
777 permission. Now a malicious user happen to know this for whatever reason.
He has control of EU server but absolutely no control over US server, only that he knows
Can he put files in US server
