CVE-2022-24755

Bareos is open source software for backup, archiving, and recovery of data
for operating systems. When Bareos Director >= 18.2 >= 18.2 but prior to
21.1.0, 20.0.6, and 19.2.12 is built and configured for PAM authentication,
it will skip authorization checks completely. Expired accounts and accounts
with expired passwords can still login. This problem will affect users that
have PAM enabled. Currently there is no authorization (e.g. check for
expired or disabled accounts), but only plain authentication (i.e. check if
username and password match). Bareos Director versions 21.1.0, 20.0.6 and
19.2.12 implement the authorization check that was previously missing. The
only workaround is to make sure that authentication fails if the user is
not authorized.
