CVSS: 5.9EPSS: 4%CPEs: 3EXPL: 0CVE-2022-32742 – Samba SMB1 Out-Of-Bounds Read Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2022-32742
A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or printer) instead of client-supplied data. The client cannot control the area of the server memory written to the file (or printer). Se ha encontrado un fallo en Samba. Algunas solicitudes de escritura de SMB1 no son comprobaban correctamente para asegurar que el cliente había enviado suficientes datos para completar la escritura, lo que permitía que el contenido de la memoria del servidor fuera escrita en el archivo (o impresora) en lugar de los datos proporcionados por el cliente. • https://lists.debian.org/debian-lts-announce/2024/04/msg00015.html https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2022-32742.html https://access.redhat.com/security/cve/CVE-2022-32742 https://bugzilla.redhat.com/show_bug.cgi?id=2108196 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2022-2031
A flaw was found in Samba. The security vulnerability occurs when KDC and the kpasswd service share a single account and set of keys, allowing them to decrypt each other's tickets. A user who has been requested to change their password, can exploit this flaw to obtain and use tickets to other services. Se ha encontrado un fallo en Samba. Una vulnerabilidad de seguridad es producida cuando el KDC y el servicio kpasswd comparten una misma cuenta y un mismo conjunto de claves, lo que les permite descifrar los tickets del otro. • https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2022-2031.html • CWE-287: Improper Authentication CWE-288: Authentication Bypass Using an Alternate Path or Channel •
CVSS: 6.8EPSS: 0%CPEs: 8EXPL: 0CVE-2021-20316 – samba: Symlink race error can allow metadata read and modify outside of the exported share
https://notcve.org/view.php?id=CVE-2021-20316
A flaw was found in the way Samba handled file/directory metadata. This flaw allows an authenticated attacker with permissions to read or modify share metadata, to perform this operation outside of the share. Se ha encontrado un fallo en la forma en que Samba maneja los metadatos de los archivos/directorios. Este fallo permite a un atacante autenticado con permisos para leer o modificar los metadatos del recurso compartido, llevar a cabo esta operación fuera del recurso compartido. • https://access.redhat.com/security/cve/CVE-2021-20316 https://bugzilla.redhat.com/show_bug.cgi?id=2009673 https://bugzilla.samba.org/show_bug.cgi?id=14842 https://security-tracker.debian.org/tracker/CVE-2021-20316 https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2021-20316.html • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2021-44141
All versions of Samba prior to 4.15.5 are vulnerable to a malicious client using a server symlink to determine if a file or directory exists in an area of the server file system not exported under the share definition. SMB1 with unix extensions has to be enabled in order for this attack to succeed. Todas las versiones de Samba anteriores a 4.15.5, son vulnerables a que un cliente malicioso use un enlace simbólico del servidor para determinar si un archivo o directorio se presenta en un área del sistema de archivos del servidor no exportada bajo la definición de recurso compartido. SMB1 con extensiones unix debe estar habilitado para que este ataque tenga éxito A vulnerability was found in Samba due to an insecure link following. By querying a symlink inside the exported share using SMB1 with unix extensions turned on, an attacker can discover if a named or directory exists on the filesystem outside the exported share. • https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2021-44141.html https://access.redhat.com/security/cve/CVE-2021-44141 https://bugzilla.redhat.com/show_bug.cgi?id=2046120 • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 8.8EPSS: 0%CPEs: 5EXPL: 0CVE-2022-0336
https://notcve.org/view.php?id=CVE-2022-0336
The Samba AD DC includes checks when adding service principals names (SPNs) to an account to ensure that SPNs do not alias with those already in the database. Some of these checks are able to be bypassed if an account modification re-adds an SPN that was previously present on that account, such as one added when a computer is joined to a domain. An attacker who has the ability to write to an account can exploit this to perform a denial-of-service attack by adding an SPN that matches an existing service. Additionally, an attacker who can intercept traffic can impersonate existing services, resulting in a loss of confidentiality and integrity. El DC de Samba AD incluye comprobaciones cuando son añadidos nombres de directores de servicio (SPN) a una cuenta para asegurar que los SPN no presentan alias con los que ya están en la base de datos. • https://access.redhat.com/security/cve/CVE-2022-0336 https://bugzilla.redhat.com/show_bug.cgi?id=2046134 https://bugzilla.samba.org/show_bug.cgi?id=14950 https://github.com/samba-team/samba/commit/1a5dc817c0c9379bbaab14c676681b42b0039a3c https://github.com/samba-team/samba/commit/c58ede44f382bd0125f761f0479c8d48156be400 https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2022-0336.html • CWE-276: Incorrect Default Permissions •
