Vulnerability discussion

Check content

To view the list of device files that are on the system, run the following command: sudo find / -perm -2 -a \( -type b -o -type c \) Check the permissions on the directories above subdirectories of the returned items. If any of the device files or their parent directories are world-writable, except device files specifically intended to be world-writable such as /dev/null, this is a finding.

Fix text

To remove the writable option for other users, run the following command: sudo chmod o-w [path to device file]

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.
