[SOLVED] seeking chmod info from wise old people

[nadeemshafi9]

if u have a file with permissions 0777 and the directory it is in has the permissions 0755, is this file still insecure can it be manipulated, i guess what im asking is, is the directories permissions the ones that are in use not the files?

 

thanks guys

I think the file can be manipulated but I'll test when I get home to my Linux laptop.

OK, after doing some testing I'm pretty sure in the situation you described, the file can be manipulated.

 

If a file has 777 permissions then pretty much all the time, anyone can manipulate it. They're only stopped if the directory doesn't have read access. Also, if the directory doesn't have write access then you won't be able to delete/create the file (but you can still write to that particular file). So be careful when using fopen with the 'x', 'a' or 'w' options. Make sure the file exists first.
