Vulnerability discussion

Data in world-writable files can be read, modified, and potentially compromised by any user on the system. World-writable files may also indicate an incorrectly written script or program that could potentially be the cause of a larger compromise to the system's integrity.

Check content

The root role is required. Check for the existence of world-writable files. # find / \( -fstype nfs -o -fstype cachefs -o -fstype autofs \ -o -fstype ctfs -o -fstype mntfs -o -fstype objfs \ -o -fstype proc \) -prune -o -type f -perm -0002 -print If output is produced, this is a finding.

Fix text

The root role is required. Change the permissions of the files identified in the check step to remove the world-writable permission. # pfexec chmod o-w [filename]

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
