The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2023:7467 advisory.

  - A path traversal vulnerability was identified in Samba when processing client pipe names connecting to     Unix domain sockets within a private directory. Samba typically uses this mechanism to connect SMB clients     to remote procedure call (RPC) services like SAMR LSA or SPOOLSS, which Samba initiates on demand.
    However, due to inadequate sanitization of incoming client pipe names, allowing a client to send a pipe     name containing Unix directory traversal characters (../). This could result in SMB clients connecting as     root to Unix domain sockets outside the private directory. If an attacker or client managed to send a pipe     name resolving to an external service using an existing Unix domain socket, it could potentially lead to     unauthorized access to the service and consequential adverse events, including compromise or service     crashes. (CVE-2023-3961)

  - A vulnerability was discovered in Samba, where the flaw allows SMB clients to truncate files, even with     read-only permissions when the Samba VFS module acl_xattr is configured with acl_xattr:ignore system     acls = yes. The SMB protocol allows opening files when the client requests read-only access but then     implicitly truncates the opened file to 0 bytes if the client specifies a separate OVERWRITE create     disposition request. The issue arises in configurations that bypass kernel file system permissions checks,     relying solely on Samba's permissions. (CVE-2023-4091)

  - A vulnerability was found in Samba's rpcecho development server, a non-Windows RPC server used to test     Samba's DCE/RPC stack elements. This vulnerability stems from an RPC function that can be blocked     indefinitely. The issue arises because the rpcecho service operates with only one worker in the main RPC     task, allowing calls to the rpcecho server to be blocked for a specified time, causing service     disruptions. This disruption is triggered by a sleep() call in the dcesrv_echo_TestSleep() function     under specific conditions. Authenticated users or attackers can exploit this vulnerability to make calls     to the rpcecho server, requesting it to block for a specified duration, effectively disrupting most     services and leading to a complete denial of service on the AD DC. The DoS affects all other services as     rpcecho runs in the main RPC task. (CVE-2023-42669)

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 MAIN 7.02, has samba packages installed that are affected by multiple vulnerabilities:

  - A path traversal vulnerability was identified in Samba when processing client pipe names connecting to     Unix domain sockets within a private directory. Samba typically uses this mechanism to connect SMB clients     to remote procedure call (RPC) services like SAMR LSA or SPOOLSS, which Samba initiates on demand.
    However, due to inadequate sanitization of incoming client pipe names, allowing a client to send a pipe     name containing Unix directory traversal characters (../). This could result in SMB clients connecting as     root to Unix domain sockets outside the private directory. If an attacker or client managed to send a pipe     name resolving to an external service using an existing Unix domain socket, it could potentially lead to     unauthorized access to the service and consequential adverse events, including compromise or service     crashes. (CVE-2023-3961)

  - An information leak vulnerability was discovered in Samba's LDAP server. Due to missing access control     checks, an authenticated but unprivileged attacker could discover the names and preserved attributes of     deleted objects in the LDAP store. (CVE-2018-14628)

  - 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)

  - A vulnerability was found in Samba's SMB2 packet signing mechanism. The SMB2 packet signing is not     enforced if an admin configured server signing = required or for SMB2 connections to Domain Controllers     where SMB2 packet signing is mandatory. This flaw allows an attacker to perform attacks, such as a man-in-     the-middle attack, by intercepting the network traffic and modifying the SMB2 messages between client and     server, affecting the integrity of the data. (CVE-2023-3347)

  - 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)

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:7408 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.
