Synopsis

The remote Samba server is potentially affected by multiple vulnerabilities.

Description

The version of Samba running on the remote host is potentially affected by multiple vulnerabilities, as follows:

- The fix in 4.6.16, 4.7.9, 4.8.4 and 4.9.7 for CVE-2018-10919 Confidential attribute disclosure via LDAP filters was insufficient and an attacker may be able to obtain confidential BitLocker recovery keys from a Samba AD DC. (CVE-2023-0614)

- The Samba AD DC administration tool, when operating against a remote LDAP server, will by default send new or reset passwords over a signed-only connection. (CVE-2023-0922)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Samba version 4.16.10, 4.17.7, or 4.18.1.
