CVSS: 7.1EPSS: 62%CPEs: 14EXPL: 0CVE-2017-12163 – Samba: Server memory information leak over SMB1
https://notcve.org/view.php?id=CVE-2017-12163
An information leak flaw was found in the way SMB1 protocol was implemented by Samba before 4.4.16, 4.5.x before 4.5.14, and 4.6.x before 4.6.8. A malicious client could use this flaw to dump server memory contents to a file on the samba share or to a shared printer, though the exact area of server memory cannot be controlled by the attacker. Se ha descubierto una vulnerabilidad de fuga de información en la manera en la que Samba, en versiones anteriores a la 4.4.16, versiones 4.5.x anteriores a la 4.5.14 y versiones 4.6.x anteriores a la 4.6.8, implementó el protocolo SMB1. Un cliente malicioso podría utilizar esta vulnerabilidad para volcar los contenidos de la memoria del servidor en un archivo en el almacenamiento de samba o en una impresora compartida, aunque el atacante no pueda controlar el área exacta de memoria del servidor. An information leak flaw was found in the way SMB1 protocol was implemented by Samba. • http://www.securityfocus.com/bid/100925 http://www.securitytracker.com/id/1039401 https://access.redhat.com/errata/RHSA-2017:2789 https://access.redhat.com/errata/RHSA-2017:2790 https://access.redhat.com/errata/RHSA-2017:2791 https://access.redhat.com/errata/RHSA-2017:2858 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-12163 https://h20566.www2.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbns03775en_us https://security.netapp.com/advisory/ntap-20170 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

smbd in Samba before 4.4.10 and 4.5.x before 4.5.6 has a denial of service vulnerability (fd_open_atomic infinite loop with high CPU usage and memory consumption) due to wrongly handling dangling symlinks. smbd en Samba versiones anteriores a 4.4.10 y 4.5.x versiones anteriores a 4.5.6, tienen una vulnerabilidad de denegación de servicio (fd_open_atomic infinite loop con un alto uso de CPU y consumo de memoria) debido a un manejo inadecuado de los enlaces simbólicos colgantes. A flaw was found in the way Samba handled dangling symlinks. An authenticated malicious Samba client could use this flaw to cause the smbd daemon to enter an infinite loop and use an excessive amount of CPU and memory. • http://www.securityfocus.com/bid/99455 https://access.redhat.com/errata/RHSA-2017:1950 https://access.redhat.com/errata/RHSA-2017:2338 https://access.redhat.com/errata/RHSA-2017:2778 https://bugs.debian.org/864291 https://bugzilla.samba.org/show_bug.cgi?id=12572 https://git.samba.org/?p=samba.git%3Ba=commit%3Bh=10c3e3923022485c720f322ca4f0aca5d7501310 https://lists.debian.org/debian-lts-announce/2019/04/msg00013.html https://access.redhat.com/security/cve/CVE-2017-9461 https: • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

https://notcve.org/view.php?id=CVE-2017-7494
Samba since version 3.5.0 and before 4.6.4, 4.5.10 and 4.4.14 is vulnerable to remote code execution vulnerability, allowing a malicious client to upload a shared library to a writable share, and then cause the server to load and execute it. Samba desde la versión 3.5.0 y anteriores a 4.6.4, versiones 4.5.10 y 4.4.14, son vulnerables a la ejecución de código remota, lo que permite que un cliente malicioso cargar una biblioteca compartida en un recurso compartido editable, y luego causar que el servidor lo cargue y ejecute. A remote code execution flaw was found in Samba. A malicious authenticated samba client, having write access to the samba share, could use this flaw to execute arbitrary code as root. Samba contains a remote code execution vulnerability, allowing a malicious client to upload a shared library to a writable share and then cause the server to load and execute it. • https://github.com/opsxcq/exploit-CVE-2017-7494 https://www.exploit-db.com/exploits/42060 https://www.exploit-db.com/exploits/42084 https://github.com/joxeankoret/CVE-2017-7494 https://github.com/homjxi0e/CVE-2017-7494 https://github.com/0xm4ud/noSAMBAnoCRY-CVE-2017-7494 https://github.com/incredible1yu/CVE-2017-7494 https://github.com/00mjk/exploit-CVE-2017-7494 https://github.com/Zer0d0y/Samba-CVE-2017-7494 https://github.com/adjaliya/-CVE-2017-7494-Samba-Exploit-PO • CWE-94: Improper Control of Generation of Code ('Code Injection') •

Samba before versions 4.6.1, 4.5.7 and 4.4.11 are vulnerable to a malicious client using a symlink race to allow access to areas of the server file system not exported under the share definition. Samba, en versiones anteriores a 4.6.1, 4.5.7 y 4.4.11, es vulnerable a un cliente malicioso que emplee una carrera symlink para permitir el acceso a áreas del sistema de archivos del servidor que no se exportan bajo la definición compartida. A race condition was found in samba server. A malicious samba client could use this flaw to access files and directories in areas of the server file system not exported under the share definitions.

It was found that Samba before versions 4.5.3, 4.4.8, 4.3.13 always requested forwardable tickets when using Kerberos authentication. A service to which Samba authenticated using Kerberos could subsequently use the ticket to impersonate Samba to other services or domain users. Se ha descubierto que Samba, en versiones anteriores a la 4.5.3, 4.4.8 y 4.3.13, siempre solicitaba tickets que podían reenviarse al emplear la autenticación de Kerberos.
