  - Netlogon RPC Elevation of Privilege Vulnerability (CVE-2022-38023)

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

The version of Samba running on the remote host is prior to 4.15.13, 4.16.x prior to 4.16.8, or 4.17.x prior to 4.17.4.  It is, therefore, affected by multiple vulnerabilities:

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:0081-1 advisory.

  - A flaw was found in Samba. The security vulnerability occurs when KDC and the kpasswd service share a     single account and set of keys, allowing them to decrypt each other's tickets. A user who has been     requested to change their password, can exploit this flaw to obtain and use tickets to other services.
    (CVE-2022-2031)

  - 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)

  - A flaw was found in Samba. The KDC accepts kpasswd requests encrypted with any key known to it. By     encrypting forged kpasswd requests with its own key, a user can change other users' passwords, enabling     full domain takeover. (CVE-2022-32744)

  - A flaw was found in Samba. Samba AD users can cause the server to access uninitialized data with an LDAP     add or modify the request, usually resulting in a segmentation fault. (CVE-2022-32745)

  - A flaw was found in the Samba AD LDAP server. The AD DC database audit logging module can access LDAP     message values freed by a preceding database module, resulting in a use-after-free issue. This issue is     only possible when modifying certain privileged attributes, such as userAccountControl. (CVE-2022-32746)

  - A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and     unwrap_des3() routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI     library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a     maliciously small packet. This flaw allows a remote user to send specially crafted malicious data to the     application, possibly resulting in a denial of service (DoS) attack. (CVE-2022-3437)

  - Netlogon RPC Elevation of Privilege Vulnerability (CVE-2022-38023)

  - PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that     may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit     platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other     platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has a similar bug.

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:0163-1 advisory.

  - A flaw was found in samba. A race condition in the password lockout code may lead to the risk of brute     force attacks being successful if special conditions are met. (CVE-2021-20251)

  - Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability (CVE-2022-37966)

  - Netlogon RPC Elevation of Privilege Vulnerability (CVE-2022-38023)

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

  - An out-of-bounds read vulnerability was found in Samba due to insufficient length checks in     winbindd_pam_auth_crap.c. When performing NTLM authentication, the client replies to cryptographic     challenges back to the server. These replies have variable lengths, and Winbind fails to check the lan     manager response length. When Winbind is used for NTLM authentication, a maliciously crafted request can     trigger an out-of-bounds read in Winbind, possibly resulting in a crash. (CVE-2022-2127)

  - Netlogon RPC Elevation of Privilege Vulnerability (CVE-2022-38023)

  - An infinite loop vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing     Spotlight mdssvc RPC packets sent by the client, the core unmarshalling function sl_unpack_loop() did not     validate a field in the network packet that contains the count of elements in an array-like structure. By     passing 0 as the count value, the attacked function will run in an endless loop consuming 100% CPU. This     flaw allows an attacker to issue a malformed RPC request, triggering an infinite loop, resulting in a     denial of service condition. (CVE-2023-34966)

  - A Type Confusion vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing     Spotlight mdssvc RPC packets, one encoded data structure is a key-value style dictionary where the keys     are character strings, and the values can be any of the supported types in the mdssvc protocol. Due to a     lack of type checking in callers of the dalloc_value_for_key() function, which returns the object     associated with a key, a caller may trigger a crash in talloc_get_size() when talloc detects that the     passed-in pointer is not a valid talloc pointer. With an RPC worker process shared among multiple client     connections, a malicious client or attacker can trigger a process crash in a shared RPC mdssvc worker     process, affecting all other clients this worker serves. (CVE-2023-34967)
