Title
Bareos's negative command ACLs can be circumvented by abbreviating commands
Summary
Bareos is open source software for backup, archiving, and recovery of data for operating systems. When a command ACL is in place and a user executes a command in bconsole using an abbreviation (i.e. "w" for "whoami") the ACL check did not apply to the full form (i.e. "whoami") but to the abbreviated form (i.e. "w"). If the command ACL is configured with negative ACL that should forbid using the "whoami" command, you could still use "w" or "who" as a command successfully. Fixes for the problem are shipped in Bareos versions 23.0.4, 22.1.6 and 21.1.11. If only positive command ACLs are used without any negation, the problem does not occur.

Title
Missing Release of Memory after Effective Lifetime in Bareos Director
Summary
Bareos is open source software for backup, archiving, and recovery of data for operating systems. When Bareos Director >= 18.2 but prior to 21.1.0, 20.0.6, and 19.2.12 is built and configured for PAM authentication, a failed PAM authentication will leak a small amount of memory. An attacker that is able to use the PAM Console (i.e. by knowing the shared secret or via the WebUI) can flood the Director with failing login attempts which will eventually lead to an out-of-memory condition in which the Director will not work anymore. Bareos Director versions 21.1.0, 20.0.6 and 19.2.12 contain a Bugfix for this problem. Users who are unable to upgrade may disable PAM authentication as a workaround.

Title
Incorrect Authorization in Bareos Director
Summary
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.

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."

Title
Authentication bypass in Bareos
Summary
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.
Severity
