Title

The /var/adm/userdb/USERDB.DISABLED file must not have an extended ACL. (Cat II impact)

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
