The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:5439 advisory.

  - A flaw was found in the way samba handled file and directory permissions. An authenticated user could use     this flaw to gain access to certain file and directory information which otherwise would be unavailable to     the attacker. (CVE-2020-14318)

  - A null pointer dereference flaw was found in samba's Winbind service in versions before 4.11.15, before     4.12.9 and before 4.13.1. A local user could use this flaw to crash the winbind service causing denial of     service. (CVE-2020-14323)

  - An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure     channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC). An attacker who     successfully exploited the vulnerability could run a specially crafted application on a device on the     network. To exploit the vulnerability, an unauthenticated attacker would be required to use MS-NRPC to     connect to a domain controller to obtain domain administrator access. Microsoft is addressing the     vulnerability in a phased two-part rollout. These updates address the vulnerability by modifying how     Netlogon handles the usage of Netlogon secure channels. For guidelines on how to manage the changes     required for this vulnerability and more information on the phased rollout, see How to manage the changes     in Netlogon secure channel connections associated with CVE-2020-1472 (updated September 28, 2020). When     the second phase of Windows updates become available in Q1 2021, customers will be notified via a revision     to this security vulnerability. If you wish to be notified when these updates are released, we recommend     that you register for the security notifications mailer to be alerted of content changes to this advisory.
    See Microsoft Technical Security Notifications. (CVE-2020-1472)

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

The version of samba installed on the remote host is prior to 4.10.16-9.56. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2021-1469 advisory.

    A flaw was found in the way samba handled file and directory permissions. An authenticated user could use     this flaw to gain access to certain file and directory information which otherwise would be unavailable to     the attacker. (CVE-2020-14318)

    A null pointer dereference flaw was found in Samba's winbind service. This flaw allows a local user to     crash the winbind service, causing a denial of service. The highest threat from this vulnerability is to     system availability. (CVE-2020-14323)

    A flaw was found in the Microsoft Windows Netlogon Remote Protocol (MS-NRPC), where it reuses a known,     static, zero-value initialization vector (IV) in AES-CFB8 mode. This flaw allows an unauthenticated     attacker to impersonate a domain-joined computer, including a domain controller, and possibly obtain     domain administratorprivileges. The highest threat from this vulnerability is to confidentiality,     integrity, as well as system availability. (CVE-2020-1472)

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

The remote Windows host is missing security update 4601363 or cumulative update 4601347. It is, therefore, affected by multiple vulnerabilities :

  - An elevation of privilege vulnerability exists when an     attacker establishes a vulnerable Netlogon secure     channel connection to a domain controller, using the     Netlogon Remote Protocol (MS-NRPC). An attacker who     successfully exploited the vulnerability could run a     specially crafted application on a device on the     network. (Enforcement mode) (CVE-2020-1472)

  - A denial of service (DoS) vulnerability. An attacker can     exploit this issue to cause the affected component to     deny system or application services. (CVE-2021-24080,     CVE-2021-24086)

  - An elevation of privilege vulnerability. An attacker can     exploit this to gain elevated privileges.
    (CVE-2021-1727, CVE-2021-24102, CVE-2021-24103,     CVE-2021-25195)

  - A remote code execution vulnerability. An attacker can     exploit this to bypass authentication and execute     unauthorized arbitrary commands. (CVE-2021-1722,     CVE-2021-24074, CVE-2021-24077, CVE-2021-24078,     CVE-2021-24083, CVE-2021-24088, CVE-2021-24094)

  - An information disclosure vulnerability. An attacker can     exploit this to disclose potentially sensitive     information. (CVE-2021-1734)

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2021-1647 advisory.

    - resolves: #1891688 - Fix CVE-2020-14323
    - resolves: #1892633 - Fix CVE-2020-14318
    - resolves: #1892639 - Fix CVE-2020-14383
    - resolves: #1879835 - Fix CVE-2020-1472

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has samba packages installed that are affected by multiple vulnerabilities:

  - All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where     if it is set with log level = 3 (or above) then the string obtained from the client, after a failed     character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange.
    In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to     terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a     crash there is harmless). (CVE-2019-14907)

  - A flaw was found in the way samba handled file and directory permissions. An authenticated user could use     this flaw to gain access to certain file and directory information which otherwise would be unavailable to     the attacker. (CVE-2020-14318)

  - A null pointer dereference flaw was found in samba's Winbind service in versions before 4.11.15, before     4.12.9 and before 4.13.1. A local user could use this flaw to crash the winbind service causing denial of     service. (CVE-2020-14323)
