But, SSH and telnet, etc. require authentication login-in and all the executables you mentioned [and others] require someone who has access to upload a harmful file to start with. Right? Once they are in there, they can do anything they please anyhow. Al.........Well, you were talking about a shared linux host, so other people, from a different account, could just upload files, and if you have a directory with 757, that user could write to it.

And if you give files 757 (or 646) permissions, then "world" can edit that file. So if you have a doc dir, you probably don't want extra files there. It's not really a security problem, but if somebody notices it, he might write files there. TijnemaI'm on a shared Linux host and have been wondering about security and directory "other" ["world"] permissions. The defaults are 755. The 'others' [world] can read them only. Is there a security hole if a dir on the doc root if a directory has permissions 757? If there is a security problem, what is it?
