Descriptions

On Junos OS, rpcbind should only be listening to port 111 on the internal routing instance (IRI). External packets destined to port 111 should be dropped. Due to an information leak vulnerability, responses were being generated from the source address of the management interface (e.g. fxp0) thus disclosing internal addressing and existence of the management interface itself. A high rate of crafted packets destined to port 111 may also lead to a partial Denial of Service (DoS). Note: Systems with fxp0 disabled or unconfigured are not vulnerable to this issue. This issue only affects Junos OS releases based on FreeBSD 10 or higher (typically Junos OS 15.1+). Administrators can confirm whether systems are running a version of Junos OS based on FreeBSD 10 or higher by typing: user@junos> show version | match kernel JUNOS OS Kernel 64-bit [20181214.223829_fbsd-builder_stable_10] Affected releases are Juniper Networks Junos OS: 15.1 versions prior to 15.1F6-S12, 15.1R7-S4; 15.1X53 versions prior to 15.1X53-D236; 16.1 versions prior to 16.1R7-S1; 16.2 versions prior to 16.2R2-S9; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R1-S8; 17.3 versions prior to 17.3R2; 17.4 versions prior to 17.4R1-S1, 17.4R1-S7, 17.4R2. This issue does not affect Junos OS releases prior to 15.1.

En Junos OS, rpcbind sólo debería estar escuchando el puerto 111 en la instancia de enrutamiento interno (IRI). Los paquetes externos destinados al puerto 111 deben ser eliminados. Debido a una vulnerabilidad de fuga de información, las respuestas se generaban a partir de la dirección de origen de la interfaz de gestión (por ejemplo, fxp0), lo que revelaba el direccionamiento interno y la existencia de la propia interfaz de gestión. Una alta tasa de paquetes elaborados destinados al puerto 111 también puede conducir a una denegación parcial de servicio (DoS). Nota: Los sistemas con fxp0 deshabilitado o no configurado no son vulnerables a este problema. Este problema sólo afecta a las versiones de Junos OS basadas en FreeBSD 10 o superior (normalmente Junos OS 15.1+). Los administradores pueden confirmar si los sistemas ejecutan una versión del Junos OS basada en FreeBSD 10 o superior escribiendo: user@junos> show version | match kernel JUNOS OS Kernel 64-bit[20181214.223829_fbsd-builder_stable_10] Las versiones afectadas son Juniper Networks Junos OS: 15.1 versiones anteriores a 15.1F6-S12, 15.1R7-S4; 15.1X53 versiones anteriores a 15.1X53-D236; 16.1 versiones anteriores a 16.1R7-S1; 16.2 versiones anteriores a 16.2R2-S9; 17.1 versiones anteriores a 17.1R3; 17.2 versiones anteriores a 17.2R1-S8; 17.3 versiones anteriores a 17.3R2; 17.4 versiones anteriores a 17.4R1-S1, 17.4R1-S7, 17.4R2. Este problema no afecta a las versiones de Junos OS anteriores a la 15.1.
