CVSS: 5.8EPSS: 0%CPEs: 9EXPL: 0CVE-2015-5296 – samba: client requesting encryption vulnerable to downgrade attack
https://notcve.org/view.php?id=CVE-2015-5296
Samba 3.x and 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3 supports connections that are encrypted but unsigned, which allows man-in-the-middle attackers to conduct encrypted-to-unencrypted downgrade attacks by modifying the client-server data stream, related to clidfs.c, libsmb_server.c, and smbXcli_base.c. Samba 3.x y 4.x en versiones anteriores a 4.1.22, 4.2.x en versiones anteriores a 4.2.7 y 4.3.x en versiones anteriores a 4.3.3 admite conexiones que están cifradas pero no firmadas, lo que permite a atacantes man-in-the-middle llevar a cabo un ataque de degradación de cifrado-a-descifrado modificando el flujo de datos cliente-servidor, relacionado con clidfs.c, libsmb_server.c y smbXcli_base.c. A man-in-the-middle vulnerability was found in the way "connection signing" was implemented by Samba. A remote attacker could use this flaw to downgrade an existing Samba client connection and force the use of plain text. • http://lists.fedoraproject.org/pipermail/package-announce/2015-December/174076.html http://lists.fedoraproject.org/pipermail/package-announce/2015-December/174391.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00033.html http://lists.opensuse.org/opensuse-security-announce& • CWE-20: Improper Input Validation CWE-345: Insufficient Verification of Data Authenticity •
CVSS: 5.3EPSS: 0%CPEs: 9EXPL: 0CVE-2015-5299 – Samba: Missing access control check in shadow copy code
https://notcve.org/view.php?id=CVE-2015-5299
The shadow_copy2_get_shadow_copy_data function in modules/vfs_shadow_copy2.c in Samba 3.x and 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3 does not verify that the DIRECTORY_LIST access right has been granted, which allows remote attackers to access snapshots by visiting a shadow copy directory. La función shadow_copy2_get_shadow_copy_data en modules/vfs_shadow_copy2.c en Samba 3.x y 4.x en versiones anteriores a 4.1.22, 4.2.x en versiones anteriores a 4.2.7 y 4.3.x en versiones anteriores a 4.3.3 no verifica que el privilegio de acceso al DIRECTORY_LIST ha sido concedido, lo que permite a atacantes remotos acceder a instantáneas visitando un directorio shadow copy. A missing access control flaw was found in Samba. A remote, authenticated attacker could use this flaw to view the current snapshot on a Samba share, despite not having DIRECTORY_LIST access rights. • http://lists.fedoraproject.org/pipermail/package-announce/2015-December/174076.html http://lists.fedoraproject.org/pipermail/package-announce/2015-December/174391.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00033.html http://lists.opensuse.org/opensuse-security-announce& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-862: Missing Authorization •
