before 2.3.20. When two passdb configuration entries exist with the same
driver and args settings, incorrect username_filter and mechanism settings
can be applied to passdb definitions. These incorrectly applied settings
can lead to an unintended security configuration and can permit privilege
escalation in certain configurations. The documentation does not advise
against the use of passdb definitions that have the same driver and args
settings. One such configuration would be where an administrator wishes to
use the same PAM configuration or passwd file for both normal and master
users but use the username_filter setting to restrict which of the users
is able to be a master user. (CVE-2022-30550)");
