SV-74145r1_rule The sudoers file must be configured to authenticate users on a per-tty basis.

Vulnerability discussion

The sudo command must be configured to prompt for the administrator user's password at least once in each newly opened Terminal window or remote login session, as this prevents a malicious user from taking advantage of an unlocked computer or an abandoned login session to bypass the normal password prompt requirement. Without the tty_tickets option, all open local and remote login sessions would be authenticated to use sudo without a password for the duration of the configured password timeout window.

Check content

To check if the tty_tickets option is set for sudo, run the following command: sudo grep tty_tickets /etc/sudoers If there is no result, this is a finding.

Fix text

Edit the /etc/sudoers file to contain the line: Defaults tty_tickets This line can be placed in the Defaults section or at the end of the 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.
