If the rights to the directory are "777", does this mean that anyone can delete anything in this folder, or write down whatever they want, as much as they want there?

Question

Access rights

Is it safe to give folders permissions 777?

Anyone from local users. Safely. Or not. Depends on how many people use the machine directly (local login/ssh/etc). Above, all this is covered by setting up services (ftp, for example), but this is an additional point of failure: if an RCE class vulnerability is found in a service, then security is sharply reduced.

Answer 2

Yes. But for this he still needs to get to the file system. In addition, the directory, in addition to permissions, also has an owner.
