CVSS: 7.5EPSS: 3%CPEs: 11EXPL: 1CVE-2016-2118 – samba: SAMR and LSA man in the middle attacks
https://notcve.org/view.php?id=CVE-2016-2118
The MS-SAMR and MS-LSAD protocol implementations in Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 mishandle DCERPC connections, which allows man-in-the-middle attackers to perform protocol-downgrade attacks and impersonate users by modifying the client-server data stream, aka "BADLOCK." Las implementaciones de protocolo MS-SAMR y MS-LSAD en Samba 3.x y 4.x en versiones anteriores a 4.2.11, 4.3.x en versiones anteriores a 4.3.8 y 4.4.x en versiones anteriores a 4.4.2 no maneja correctamente las conexiones DCERPC, lo que permite a atacantes man-in-the-middle llevar a cabo ataques de desactualización de protocolo y hacerse pasar por usuarios modificando el flujo de datos cliente-servidor, también conocida como "BADLOCK". A protocol flaw, publicly referred to as Badlock, was found in the Security Account Manager Remote Protocol (MS-SAMR) and the Local Security Authority (Domain Policy) Remote Protocol (MS-LSAD). Any authenticated DCE/RPC connection that a client initiates against a server could be used by a man-in-the-middle attacker to impersonate the authenticated user against the SAMR or LSA service on the server. As a result, the attacker would be able to get read/write access to the Security Account Manager database, and use this to reveal all passwords or any other potentially sensitive information in that database. • https://github.com/nickanderson/cfengine-CVE-2016-2118 http://badlock.org http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182185.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182272.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182288.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00021.html http://lists.opensuse.org/opensuse-security- • CWE-254: 7PK - Security Features CWE-300: Channel Accessible by Non-Endpoint •

https://notcve.org/view.php?id=CVE-2016-2111
The NETLOGON service in Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2, when a domain controller is configured, allows remote attackers to spoof the computer name of a secure channel's endpoint, and obtain sensitive session information, by running a crafted application and leveraging the ability to sniff network traffic, a related issue to CVE-2015-0005. El servicio NETLOGON en Samba 3.x y 4.x en versiones anteriores a 4.2.11, 4.3.x en versiones anteriores a 4.3.8 y 4.4.x en versiones anteriores a 4.4.2, cuando un controlador de dominio está configurado, permite a atacantes remotos suplantar el nombre del computador de un dispositivo final de un canal seguro y obtener información sensible de sesión, ejecutando una aplicación manipulada y aprovechando la habilidad para husmear tráfico de red, un problema relacionado con CVE-2015-0005. It was discovered that Samba configured as a Domain Controller would establish a secure communication channel with a machine using a spoofed computer name. A remote attacker able to observe network traffic could use this flaw to obtain session-related information about the spoofed machine. • http://badlock.org http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182185.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182272.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182288.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00022.html http://lists.opensuse.or • CWE-254: 7PK - Security Features CWE-290: Authentication Bypass by Spoofing •

https://notcve.org/view.php?id=CVE-2016-2112
The bundled LDAP client library in Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not recognize the "client ldap sasl wrapping" setting, which allows man-in-the-middle attackers to perform LDAP protocol-downgrade attacks by modifying the client-server data stream. El paquete de la librería cliente LDAP en Samba 3.x y 4.x en versiones anteriores a 4.2.11, 4.3.x en versiones anteriores a 4.3.8 y 4.4.x en versiones anteriores a 4.4.2 no reconoce el ajuste "client ldap sasl wrapping", lo que permite a atacantes man-in-the-middle llevar a cabo ataques de degradación de protocolo LDAP modificando el flujo de datos cliente-servidor. It was found that Samba's LDAP implementation did not enforce integrity protection for LDAP connections. A man-in-the-middle attacker could use this flaw to downgrade LDAP connections to use no integrity protection, allowing them to hijack such connections. • http://badlock.org http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182185.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182272.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182288.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00022.html http://lists.opensuse.or • CWE-254: 7PK - Security Features CWE-300: Channel Accessible by Non-Endpoint •

https://notcve.org/view.php?id=CVE-2015-5370
Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not properly implement the DCE-RPC layer, which allows remote attackers to perform protocol-downgrade attacks, cause a denial of service (application crash or CPU consumption), or possibly execute arbitrary code on a client system via unspecified vectors. Samba 3.x y 4.x en versiones anteriores a 4.2.11, 4.3.x en versiones anteriores a 4.3.8 y 4.4.x en versiones anteriores a 4.4.2 no implementa correctamente la capa DCE-RPC, lo que permite a atacantes remotos llevar a cabo protocol-downgrade attacks, provocar una denegación de servicio (caída de aplicación o consumo de CPU), o posiblemente ejecutar código arbitrario en un sistema cliente a través de vectores no especificados. Multiple flaws were found in Samba's DCE/RPC protocol implementation. A remote, authenticated attacker could use these flaws to cause a denial of service against the Samba server (high CPU load or a crash) or, possibly, execute arbitrary code with the permissions of the user running Samba (root). This flaw could also be used to downgrade a secure DCE/RPC connection by a man-in-the-middle attacker taking control of an Active Directory (AD) object and compromising the security of a Samba Active Directory Domain Controller (DC). • http://badlock.org http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182185.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182272.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182288.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00022.html http://lists.opensuse.or •
