The Linux PAM system must not grant sole access to admin privileges to the first user who logs into the console.

From SUSE Linux Enterprise Server v11 for System z

SV-44665r1_rule The Linux PAM system must not grant sole access to admin privileges to the first user who logs into the console.

Vulnerability discussion

If an unauthorized user has been granted privileged access while logged in at the console, the security posture of a system could be greatly compromised. Additionally, such a situation could deny legitimate root access from another terminal.

Check content

Ensure the pam_console.so module is not configured in any files in /etc/pam.d by: # cd /etc/pam.d # grep pam_console.so * Or # ls –la /etc/security/console.perms If either the pam_console.so entry or the file /etc/security/console.perms is found then this is a finding.

Fix text

Ensure PAM is not configured to grant sole access of administrative privileges to the first user logged in at the console. Remove the console.perms file if it exists: # rm /etc/security/console.perms

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.
