Vulnerability discussion

A unique user name is the first part of the identification and authentication process. If user names are not unique, there can be no accountability on the system for auditing purposes. Multiple accounts sharing the same name could result in the Denial of Service to one or both of the accounts or unauthorized access to files or privileges.

Check content

Verify the consistency of the assigned home directories in the authentication database. For Trusted Mode: # authck -av For SMSE: # pwck If any duplicate account names are found, this is a finding.

Fix text

Determine if the duplicate accounts have the same or different UIDs. # cat /etc/passwd | cut -f 1,1 -d “:” | sort | uniq -d If the UIDs are different, the account name must be changed. If the UIDs are the same, disable/remove one of the two (or more) password file entries via the SAM/SMH interface.

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.
