Описание
Bareos before version 19.2.8 and earlier allows a malicious client to communicate with the director without knowledge of the shared secret if the director allows client initiated connection and connects to the client itself. The malicious client can replay the Bareos director's cram-md5 challenge to the director itself leading to the director responding to the replayed challenge. The response obtained is then a valid reply to the directors original challenge. This is fixed in version 19.2.8.

Workaround: Make sure the director will not connect to a client that can
initiate connections. As a rule: every client with "Connection From Client
To Director = yes" must also set "Connection From Director To Client = no".
