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') •

https://notcve.org/view.php?id=CVE-2019-3870
A vulnerability was found in Samba from version (including) 4.9 to versions before 4.9.6 and 4.10.2. During the creation of a new Samba AD DC, files are created in a private subdirectory of the install location. This directory is typically mode 0700, that is owner (root) only access. However in some upgraded installations it will have other permissions, such as 0755, because this was the default before Samba 4.8. Within this directory, files are created with mode 0666, which is world-writable, including a sample krb5.conf, and the list of DNS names and servicePrincipalName values to update. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3870 https://bugzilla.samba.org/show_bug.cgi?id=13834 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6354GALK73CZWQKFUG7AWB6EIEGFMF62 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JTJVFA3RZ6G2IZDTVKLHRMX6QBYA4GPA https://support.f5.com/csp/article/K20804356 https://www.samba.org/samba/security/CVE-2019-3870.html https://www.synology.com/security/advisory/Synology_SA_19 • CWE-276: Incorrect Default Permissions •
