Discussion

World-writable files and directories make it easy for a malicious user to place potentially compromising files on the system. The only authorized public directories are those temporary directories supplied with the system or those designed to be temporary file repositories. The setting is normally reserved for directories used by the system and by users for temporary file storage, (e.g., /tmp), and for directories requiring global read/write access.

Check the system for world-writable files.

Procedure:
# find / -perm -2 -a \( -type d -o -type f \) -exec ls -ld {} \;

If any world-writable files are located, except those required for system operation such as /tmp and /dev/null, this is a finding.
