The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:0008 advisory.

    Samba is an open-source implementation of the Server Message Block (SMB) protocol and the related Common     Internet File System (CIFS) protocol, which allow PC-compatible machines to share files, printers, and     various information.

    Security Fix(es):

    * samba: Active Directory (AD) domain user could become root on domain members (CVE-2020-25717)

    * samba: SMB1 client connections can be downgraded to plaintext authentication (CVE-2016-2124)

    * samba: Subsequent DCE/RPC fragment injection vulnerability (CVE-2021-23192)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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.

According to the versions of the samba packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to     retrieve the plaintext password sent over the wire even if Kerberos authentication was required.
    (CVE-2016-2124)

  - A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use     this flaw to cause possible privilege escalation. (CVE-2020-25717)

  - A flaw was found in the way samba, as an Active Directory Domain Controller, is able to support an RODC     (read-only domain controller). This would allow an RODC to print administrator tickets. (CVE-2020-25718)

  - A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-     based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did     not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total     domain compromise. (CVE-2020-25719)

  - Multiple flaws were found in the way samba AD DC implemented access and conformance checking of stored     data. An attacker could use this flaw to cause total domain compromise. (CVE-2020-25722)

  - A null pointer de-reference was found in the way samba kerberos server handled missing sname in TGS-REQ     (Ticket Granting Server - Request). An authenticated user could use this flaw to crash the samba server.
    (CVE-2021-3671)

According to the versions of the samba packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to     retrieve the plaintext password sent over the wire even if Kerberos authentication was required.
    (CVE-2016-2124)

The result could include total     domain compromise. (CVE-2020-25719)

  - Kerberos acceptors need easy access to stable AD identifiers (eg objectSid). Samba as an AD DC now     provides a way for Linux applications to obtain a reliable SID (and samAccountName) in issued tickets.
    (CVE-2020-25721)

  - Multiple flaws were found in the way samba AD DC implemented access and conformance checking of stored     data. An attacker could use this flaw to cause total domain compromise. (CVE-2020-25722)

  - A null pointer de-reference was found in the way samba kerberos server handled missing sname in TGS-REQ     (Ticket Granting Server - Request). An authenticated user could use this flaw to crash the samba server.
    (CVE-2021-3671)

  - In DCE/RPC it is possible to share the handles (cookies for resource state) between multiple connections     via a mechanism called 'association groups'. These handles can reference connections to our sam.ldb     database. However while the database was correctly shared, the user credentials state was only pointed at,     and when one connection within that association group ended, the database would be left pointing at an     invalid 'struct session_info'. The most likely outcome here is a crash, but it is possible that the use-     after-free could instead allow different user state to be pointed at and this might allow more privileged     access. (CVE-2021-3738)

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has samba packages installed that are affected by multiple vulnerabilities:

  - A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to     retrieve the plaintext password sent over the wire even if Kerberos authentication was required.
    (CVE-2016-2124)

  - A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use     this flaw to cause possible privilege escalation. (CVE-2020-25717)

  - The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide ...enhanced compatibility     with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver. Samba versions prior to     4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via     specially crafted extended file attributes. A remote attacker with write access to extended file     attributes can execute arbitrary code with the privileges of smbd, typically root. (CVE-2021-44142)

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

  - A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix     group ids (gids). The code that performs this had a flaw that could allow it to read data beyond the end     of the array in the case where a negative cache entry had been added to the mapping cache. This could     cause the calling code to return those values into the process token that stores the group membership for     a user. The highest threat from this vulnerability is to data confidentiality and integrity.
    (CVE-2021-20254)

  - A null pointer de-reference was found in the way samba kerberos server handled missing sname in TGS-REQ     (Ticket Granting Server - Request). An authenticated user could use this flaw to crash the samba server.

A remote attacker with write access to extended file     attributes can execute arbitrary code with the privileges of smbd, typically root. (CVE-2021-44142)

  - A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client     had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or     printer) instead of client-supplied data. The client cannot control the area of the server memory written     to the file (or printer). (CVE-2022-32742)

The remote NewStart CGSL host, running version MAIN 6.06, has samba packages installed that are affected by multiple vulnerabilities:

  - The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide ...enhanced compatibility     with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver. Samba versions prior to     4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via     specially crafted extended file attributes. A remote attacker with write access to extended file     attributes can execute arbitrary code with the privileges of smbd, typically root. (CVE-2021-44142)

  - Logic error in the SID/Name translation functionality in smbd in Samba 3.0.23d through 3.0.25pre2 allows     local users to gain temporary privileges and execute SMB/CIFS protocol operations via unspecified vectors     that cause the daemon to transition to the root user. (CVE-2007-2444)

  - Samba 3.2.0 uses weak permissions (0666) for the (1) group_mapping.tdb and (2) group_mapping.ldb files,     which allows local users to modify the membership of Unix groups. (CVE-2008-3789)

  - smbd in Samba 3.0.29 through 3.2.4 might allow remote attackers to read arbitrary memory and cause a     denial of service via crafted (1) trans, (2) trans2, and (3) nttrans requests, related to a cut&paste     error that causes an improper bounds check to be performed. (CVE-2008-4314)

  - smbd in Samba 3.3.11, 3.4.6, and 3.5.0, when libcap support is enabled, runs with the CAP_DAC_OVERRIDE     capability, which allows remote authenticated users to bypass intended file permissions via standard     filesystem operations with any client. (CVE-2010-0728)
