Issue to be resolved
Potential loss of data through world write directories as they allow other users to unintentionally or maliciously delete data you have in world writeable directories.
Solution
1. Run these command to determine if you have any world write directories:
cd $HOME
find ${HOME}/ -xdev -perm -o=w ! -type l -ls >& home_world_write_files.txtcd $NOBACKUP
find ${NOBACKUP}/ -xdev -perm -o=w ! -type l -ls >& nobackup_world_write_files.txtIf you own project nobackup spaces, you should do the same there.
2. If the above commands return any world writeable directories, change them with this command:
chmod o-w dirname
Where you substitute dirname with the actual directory name.
3. If you find you have a lot of world write directories in your home or nobackup directory, check your umask with this command:
$ umaskIf it isn’t “77”, which is the default, we highly recommend that you change it with this command:
$ umask 77
to protect your data from unintentional or malicious deletion by processes run by other Discover users.
