Fix Recommendation

Configure all world-writable directories to have the sticky bit set to prevent unauthorized and unintended information transferred via shared system resources.

Set the sticky bit on all world-writable directories using the command, replace "[World-Writable Directory]" with any directory path missing the sticky bit:

$ chmod a+t [World-Writable Directory]

Check Contents

Verify all world-writable directories have the sticky bit set.

Determine if all world-writable directories have the sticky bit set using the following command:

$ sudo find / -type d \( -perm -0002 -a ! -perm -1000 \) -print 2>/dev/null

drwxrwxrwt 7 root root 4096 Jul 26 11:19 /tmp

If any of the returned directories are world-writable and do not have the sticky bit set, this is a finding.
