CVSS: 6.5EPSS: 0%CPEs: 82EXPL: 0CVE-2023-44204 – Junos OS and Junos OS Evolved: The rpd will crash upon receiving a malformed BGP UPDATE message
https://notcve.org/view.php?id=CVE-2023-44204
An Improper Validation of Syntactic Correctness of Input vulnerability in Routing Protocol Daemon (rpd) Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network based attacker to cause a Denial of Service (DoS). When a malformed BGP UPDATE packet is received over an established BGP session, the rpd crashes and restarts. This issue affects both eBGP and iBGP implementations. This issue affects: Juniper Networks Junos OS * 21.4 versions prior to 21.4R3-S4; * 22.1 versions prior to 22.1R3-S3; * 22.2 versions prior to 22.2R3-S2; * 22.3 versions prior to 22.3R2-S2, 22.3R3; * 22.4 versions prior to 22.4R2-S1, 22.4R3; * 23.2 versions prior to 23.2R1, 23.2R2; Juniper Networks Junos OS Evolved * 21.4 versions prior to 21.4R3-S5-EVO; * 22.1 versions prior to 22.1R3-S3-EVO; * 22.2 versions prior to 22.2R3-S3-EVO; * 22.3 versions prior to 22.3R2-S2-EVO; * 22.4 versions prior to 22.4R3-EVO; * 23.2 versions prior to 23.2R2-EVO; Una validación inadecuada de la corrección sintáctica de la vulnerabilidad de entrada en Routing Protocol Daemon (rpd) Juniper Networks Junos OS y Junos OS Evolved permite que un atacante basado en red no autenticado provoque una Denegación de Servicio (DoS). Cuando se recibe un paquete de ACTUALIZACIÓN de BGP con formato incorrecto a través de una sesión BGP establecida, el rpd falla y se reinicia. Este problema afecta tanto a las implementaciones de eBGP como de iBGP. Este problema afecta a: Juniper Networks Junos OS * versiones 21.4 anteriores a 21.4R3-S4; * Versiones 22.1 anteriores a 22.1R3-S3; * Versiones 22.2 anteriores a 22.2R3-S2; * Versiones 22.3 anteriores a 22.3R2-S2, 22.3R3; * Versiones 22.4 anteriores a 22.4R2-S1, 22.4R3; * Versiones 23.2 anteriores a 23.2R1, 23.2R2; Juniper Networks Junos OS Evolved * Versiones 21.4 anteriores a 21.4R3-S5-EVO; * Versiones 22.1 anteriores a 22.1R3-S3-EVO; * Versiones 22.2 anteriores a 22.2R3-S3-EVO; * Versiones 22.3 anteriores a 22.3R2-S2-EVO; * Versiones 22.4 anteriores a 22.4R3-EVO; * Versiones 23.2 anteriores a 23.2R2-EVO; • https://supportportal.juniper.net/JSA73170 • CWE-20: Improper Input Validation CWE-1286: Improper Validation of Syntactic Correctness of Input •
CVSS: 5.4EPSS: 0%CPEs: 39EXPL: 0CVE-2023-44195 – Junos OS Evolved: Packets which are not destined to the router can reach the RE
https://notcve.org/view.php?id=CVE-2023-44195
An Improper Restriction of Communication Channel to Intended Endpoints vulnerability in the NetworkStack agent daemon (nsagentd) of Juniper Networks Junos OS Evolved allows an unauthenticated network based attacker to cause limited impact to the availability of the system. If specific packets reach the Routing-Engine (RE) these will be processed normally even if firewall filters are in place which should have prevented this. This can lead to a limited, increased consumption of resources resulting in a Denial-of-Service (DoS), and unauthorized access. CVE-2023-44196 is a prerequisite for this issue. This issue affects Juniper Networks Junos OS Evolved: * 21.3-EVO versions prior to 21.3R3-S5-EVO; * 21.4-EVO versions prior to 21.4R3-S4-EVO; * 22.1-EVO version 22.1R1-EVO and later; * 22.2-EVO version 22.2R1-EVO and later; * 22.3-EVO versions prior to 22.3R2-S2-EVO, 22.3R3-S1-EVO; * 22.4-EVO versions prior to 22.4R3-EVO. This issue doesn't not affected Junos OS Evolved versions prior to 21.3R1-EVO. Una vulnerabilidad de Restricción Inadecuada del Canal de Comunicación a los Endpoints Previstos en el daemon del agente NetworkStack (nsagentd) de Juniper Networks Junos OS Evolved permite que un atacante basado en red no autenticado cause un impacto limitado en la disponibilidad del sistema. Si paquetes específicos llegan al Routing-Engine (RE), se procesarán normalmente incluso si existen filtros de firewall que deberían haberlo impedido. Esto puede provocar un consumo mayor y limitado de recursos, lo que resulta en una Denegación de Servicio (DoS) y un acceso no autorizado. • https://supportportal.juniper.net/JSA73160 • CWE-923: Improper Restriction of Communication Channel to Intended Endpoints •
CVSS: 7.5EPSS: 0%CPEs: 85EXPL: 0CVE-2023-44175 – Junos OS and Junos OS Evolved: Receipt of a specific genuine PIM packet causes RPD crash
https://notcve.org/view.php?id=CVE-2023-44175
A Reachable Assertion vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows to send specific genuine PIM packets to the device resulting in rpd to crash causing a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. Note: This issue is not noticed when all the devices in the network are Juniper devices. This issue affects Juniper Networks: Junos OS: * All versions prior to 20.4R3-S7; * 21.2 versions prior to 21.2R3-S5; * 21.3 versions prior to 21.3R3-S4; * 21.4 versions prior to 21.4R3-S4; * 22.1 versions prior to 22.1R3-S4; * 22.2 versions prior to 22.2R3; * 22.3 versions prior to 22.3R3; * 22.4 versions prior to 22.4R3. Junos OS Evolved: * All versions prior to 22.3R3-EVO; * 22.4-EVO versions prior to 22.4R3-EVO; * 23.2-EVO versions prior to 23.2R1-EVO. Una vulnerabilidad de aserción accesible en Routing Protocol Daemon (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite enviar paquetes PIM genuinos específicos al dispositivo, lo que provoca que rpd falle y provoque una Denegación de Servicio (DoS). La recepción y procesamiento continuo de este paquete creará una condición sostenida de Denegación de Servicio (DoS). Nota: Este problema no se detecta cuando todos los dispositivos de la red son dispositivos Juniper. Este problema afecta a Juniper Networks: Junos OS: * Todas las versiones anteriores a 20.4R3-S7; * Versiones 21.2 anteriores a 21.2R3-S5; * Versiones 21.3 anteriores a 21.3R3-S4; * Versiones 21.4 anteriores a 21.4R3-S4; * Versiones 22.1 anteriores a 22.1R3-S4; * Versiones 22.2 anteriores a 22.2R3; * Versiones 22.3 anteriores a 22.3R3; * Versiones 22.4 anteriores a 22.4R3. • https://supportportal.juniper.net/JSA73141 • CWE-617: Reachable Assertion •
CVSS: 6.1EPSS: 0%CPEs: 44EXPL: 0CVE-2023-44190 – Junos OS Evolved: PTX10001, PTX10004, PTX10008, PTX10016: MAC address validation bypass vulnerability
https://notcve.org/view.php?id=CVE-2023-44190
An Origin Validation vulnerability in MAC address validation of Juniper Networks Junos OS Evolved on PTX10001, PTX10004, PTX10008, and PTX10016 devices allows a network-adjacent attacker to bypass MAC address checking, allowing MAC addresses not intended to reach the adjacent LAN to be forwarded to the downstream network. Due to this issue, the router will start forwarding traffic if a valid route is present in forwarding-table, causing a loop and congestion in the downstream layer-2 domain connected to the device. This issue affects Juniper Networks Junos OS Evolved on PTX10001, PTX10004, PTX10008, and PTX10016: * All versions prior to 21.4R3-S5-EVO; * 22.1 versions prior to 22.1R3-S4-EVO; * 22.2 versions 22.2R1-EVO and later; * 22.3 versions prior to 22.3R2-S2-EVO, 22.3R3-S1-EVO; * 22.4 versions prior to 22.4R2-S1-EVO, 22.4R3-EVO; * 23.2 versions prior to 23.2R1-S1-EVO, 23.2R2-EVO. Una vulnerabilidad de validación de origen en la validación de direcciones MAC de Juniper Networks Junos OS Evolved en dispositivos PTX10001, PTX10004, PTX10008 y PTX10016 permite que un atacante adyacente a la red omita la verificación de direcciones MAC, lo que permite reenviar direcciones MAC que no están destinadas a llegar a la LAN adyacente a la red descendente. Debido a este problema, el router comenzará a reenviar tráfico si hay una ruta válida en la tabla de reenvío, lo que provocará un bucle y una congestión en el dominio de capa 2 descendente conectado al dispositivo. Este problema afecta a Juniper Networks Junos OS Evolved en PTX10001, PTX10004, PTX10008 y PTX10016: * Todas las versiones anteriores a 21.4R3-S5-EVO; * Versiones 22.1 anteriores a 22.1R3-S4-EVO; * 22.2 versiones 22.2R1-EVO y posteriores; * Versiones 22.3 anteriores a 22.3R2-S2-EVO, 22.3R3-S1-EVO; * Versiones 22.4 anteriores a 22.4R2-S1-EVO, 22.4R3-EVO; * Versiones 23.2 anteriores a 23.2R1-S1-EVO, 23.2R2-EVO. • https://supportportal.juniper.net/JSA73154 • CWE-346: Origin Validation Error •
