CVSS: 3.6EPSS: 0%CPEs: 9EXPL: 2CVE-2012-6150 – samba: pam_winbind fails open when non-existent group specified to require_membership_of
https://notcve.org/view.php?id=CVE-2012-6150
The winbind_name_list_to_sid_string_list function in nsswitch/pam_winbind.c in Samba through 4.1.2 handles invalid require_membership_of group names by accepting authentication by any user, which allows remote authenticated users to bypass intended access restrictions in opportunistic circumstances by leveraging an administrator's pam_winbind configuration-file mistake. La función winbind_name_list_to_sid_string_list en nsswitch/pam_winbind.c en Samba hasta v4.1.2 maneja nombres de grupo require_membership_of inválidos aceptando autenticación de cualquier usuario, lo cual permite a usuarios autenticados remotamente sortear restricciones de acceso en circunstancias oportunistas mediante el aprovechamiento de un error en el fichero de configuración de administración pam_winbind. • http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136864.html http://lists.fedoraproject.org/pipermail/package-announce/2014-June/134717.html http://lists.opensuse.org/opensuse-security-announce/2014-01/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00048.html http://lists.opensuse.org/opensuse-updates/2013-12/msg00088.html http://lists.opensuse.org/opensuse-updates/2014-03/msg00063. • CWE-20: Improper Input Validation •

Samba 4.0.x before 4.0.11 and 4.1.x before 4.1.1, when LDAP or HTTP is provided over SSL, uses world-readable permissions for a private key, which allows local users to obtain sensitive information by reading the key file, as demonstrated by access to the local filesystem on an AD domain controller. Samba 4.0.x anteriores a 4.0.11 y 4.1.x anteriores a 4.1.1, cuando LDAP o HTTP se proporcionan sobre SSL, utilizan permisos de lectura globales para una clave privada, lo cual permite a ususarios locales obtener información sensible mediante la lectura del fichero de la clave, como demostrado al acceder al sistema de ficheros local en un controlador de dominio AD. • http://lists.opensuse.org/opensuse-updates/2013-11/msg00083.html http://lists.opensuse.org/opensuse-updates/2013-12/msg00088.html http://security.gentoo.org/glsa/glsa-201502-15.xml http://www.samba.org/samba/history/samba-4.0.11.html http://www.samba.org/samba/history/samba-4.1.1.html http://www.samba.org/samba/security/CVE-2013-4476 • CWE-310: Cryptographic Issues •

Samba 4.x before 4.0.4, when configured as an Active Directory domain controller, uses world-writable permissions on non-default CIFS shares, which allows remote authenticated users to read, modify, create, or delete arbitrary files via standard filesystem operations. Samba v4.x anterior a v4.0.4, cuando se configura como un controlador de dominio del Directorio ACtivo, utiliza permisos de escritura globales sobre CIFS shares que no están por defecto, lo que permite a usuarios autenticados remotamente leer, modificar, crear o eliminar archivos arbitrariamente a través de operaciones convencionales en el sistema de archivos. • http://www.samba.org/samba/ftp/patches/security/samba-4.0.3-CVE-2013-1863.patch http://www.samba.org/samba/security/CVE-2013-1863 • CWE-264: Permissions, Privileges, and Access Controls •
