Vulnerability discussion

If a user is assigned a duplicate user name, it will create and have access to files with the first UID for that username in passwd.

Check content

The root role is required. Identify any duplicate user names. # getent passwd | awk -F: '{print $1}' | uniq -d If output is produced, this is a finding.

Fix text

The root role is required. Correct or justify any items discovered in the Check step. Determine if there are any duplicate user names, and work with their respective owners to determine the best course of action in accordance with site policy. Delete or change the user name of duplicate users.

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.
