All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue, where the S4U (MS-SFU) Kerberos delegation model includes a feature allowing for a subset of clients to be opted out of constrained delegation in any way, either S4U2Self or regular Kerberos authentication, by forcing all tickets for these clients to be non-forwardable. In AD this is implemented by a user attribute delegation_not_allowed (aka not-delegated), which translates to disallow-forwardable. However the Samba AD DC does not do that for S4U2Self and does set the forwardable flag even if the impersonated client has the not-delegated flag set. Todas las versiones de Samba 4.xx anteriores a 4.9.17, versiones 4.10.x anteriores a 4.10.11 y versiones 4.11.x anteriores a 4.11.3, presentan un problema, donde el modelo de delegación de Kerberos S4U (MS-SFU) incluye una funcionalidad que permite a un subconjunto de clientes ser excluidos de la delegación restringida de cualquier manera, ya sea S4U2Self o autenticación Kerberos regular, al forzar que todos los tickets para estos clientes no sean reenviables. En AD, esto es implementado mediante un atributo de usuario delegation_not_allowed (también se conoce como no delegado), que se traduce como no permitido-reenviable. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00038.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14870 https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html https://lists.debian.org/debian-lts-announce/2022/11/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PJH3ROOFYMOATD2UEPC47P5RPBDTY77E https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WNKA4YIPV7AZR7KK3GW6L3HKGHSGJZFE https: • CWE-285: Improper Authorization CWE-287: Improper Authentication •
CVSS: 6.5EPSS: 0%CPEs: 5EXPL: 0CVE-2019-10218 – samba: smb client vulnerable to filenames containing path separators
https://notcve.org/view.php?id=CVE-2019-10218
A flaw was found in the samba client, all samba versions before samba 4.11.2, 4.10.10 and 4.9.15, where a malicious server can supply a pathname to the client with separators. This could allow the client to access files and folders outside of the SMB network pathnames. An attacker could use this vulnerability to create files outside of the current working directory using the privileges of the client user. Se encontró un fallo en el cliente de samba, todas las versiones de samba anteriores a samba 4.11.2, 4.10.10 y 4.9.15, donde un servidor malicioso puede suministrar un nombre de ruta al cliente con separadores. Esto podría permitir al cliente acceder a archivos y carpetas fuera de los nombres de ruta de la red SMB. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00015.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10218 https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html https://lists.debian.org/debian-lts-announce/2023/09/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OKPYHDFI7HRELVXBE5J4MTGSI35AKFBI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UMIYCYXCPRTVCVZ3TP6ZGPJ6RZS3IX4G https: • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

A flaw was found in Samba, all versions starting samba 4.5.0 before samba 4.9.15, samba 4.10.10, samba 4.11.2, in the way it handles a user password change or a new password for a samba user. The Samba Active Directory Domain Controller can be configured to use a custom script to check for password complexity. This configuration can fail to verify password complexity when non-ASCII characters are used in the password, which could lead to weak passwords being set for samba users, making it vulnerable to dictionary attacks. Se encontró un fallo en Samba, todas las versiones iniciando samba versiones 4.5.0 anteriores a samba 4.9.15, samba versión 4.10.10, samba versión 4.11.2, en la manera en que maneja un cambio de contraseña de usuario o una nueva contraseña para un usuario de samba. El Controlador de Dominio Active Directory de Samba puede ser configurado para usar un script personalizado para comprobar la complejidad de la contraseña. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00015.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14833 https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html https://lists.debian.org/debian-lts-announce/2023/09/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OKPYHDFI7HRELVXBE5J4MTGSI35AKFBI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UMIYCYXCPRTVCVZ3TP6ZGPJ6RZS3IX4G https: • CWE-305: Authentication Bypass by Primary Weakness CWE-521: Weak Password Requirements •
