Kerentanan Authentication Bypass by Capture-replay pada bareos. Skor CVSS 3.1 6.8 (Medium) menurut NVD.

Deskripsi (NVD)

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.
