SV-52441r1_rule The /var/adm/userdb/USERDB.DISABLED file must not have an extended ACL.

Vulnerability discussion

Unless the userdb is required, the /var/adm/userdb/USERDB.DISABLED file must be created to disable the use of per-user security attributes in the user database. Attributes in the user database override the system-wide settings configured in /etc/default/security. If the system-wide configuration is overridden maliciously, users may gain unauthorized system access.

Check content

If the system is configured for Trusted Mode, this check is not applicable. For SMSE: If the userdb is required, this check is not applicable. Verify the file has no extended ACL. # ls -lL /var/adm/userdb/USERDB.DISABLED If the permissions include a “+”, the file has an extended ACL, this is a finding.

Fix text

If the system is operating in Trusted Mode, no fix is required. For SMSE: Remove the optional ACL from the file. # chacl -z /var/adm/userdb/USERDB.DISABLED

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.
