CVSS: 6.5EPSS: 0%CPEs: 93EXPL: 0CVE-2023-44203 – Junos OS: QFX5000 Series, EX2300, EX3400, EX4100, EX4400 and EX4600: Packet flooding will occur when IGMP traffic is sent to an isolated VLAN
https://notcve.org/view.php?id=CVE-2023-44203
An Improper Check or Handling of Exceptional Conditions vulnerability in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS on QFX5000 Series, EX2300, EX3400, EX4100, EX4400 and EX4600 allows a adjacent attacker to send specific traffic, which leads to packet flooding, resulting in a Denial of Service (DoS). When a specific IGMP packet is received in an isolated VLAN, it is duplicated to all other ports under the primary VLAN, which causes a flood. This issue affects QFX5000 series, EX2300, EX3400, EX4100, EX4400 and EX4600 platforms only. This issue affects Juniper Junos OS on on QFX5000 Series, EX2300, EX3400, EX4100, EX4400 and EX4600: * All versions prior to 20.4R3-S5; * 21.1 versions prior to 21.1R3-S4; * 21.2 versions prior to 21.2R3-S3; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R3-S2; * 22.1 versions prior to 22.1R3; * 22.2 versions prior to 22.2R3; * 22.3 versions prior to 22.3R2. Una vulnerabilidad de verificación o manejo inadecuado de condiciones excepcionales en Packet Forwarding Engine (pfe) de Juniper Networks Junos OS en las series QFX5000, EX2300, EX3400, EX4100, EX4400 y EX4600 permite que un atacante adyacente envíe tráfico específico, lo que provoca una inundación de paquetes. resultando en una Denegación de Servicio (DoS). Cuando se recibe un paquete IGMP específico en una VLAN aislada, se duplica en todos los demás puertos de la VLAN principal, lo que provoca una inundación. Este problema afecta únicamente a las series QFX5000, EX2300, EX3400, EX4100, EX4400 y EX4600. Este problema afecta a Juniper Junos OS en las series QFX5000, EX2300, EX3400, EX4100, EX4400 y EX4600: * Todas las versiones anteriores a 20.4R3-S5; * Versiones 21.1 anteriores a 21.1R3-S4; * Versiones 21.2 anteriores a 21.2R3-S3; * Versiones 21.3 anteriores a 21.3R3-S5; * Versiones 21.4 anteriores a 21.4R3-S2; * Versiones 22.1 anteriores a 22.1R3; * Versiones 22.2 anteriores a 22.2R3; * Versiones 22.3 anteriores a 22.3R2. • https://supportportal.juniper.net/JSA73169 • CWE-703: Improper Check or Handling of Exceptional Conditions •

CVSS: 7.5EPSS: 0%CPEs: 98EXPL: 0CVE-2023-44198 – Junos OS: SRX Series and MX Series: SIP ALG doesn't drop specifically malformed retransmitted SIP packets
https://notcve.org/view.php?id=CVE-2023-44198
An Improper Check for Unusual or Exceptional Conditions vulnerability in the SIP ALG of Juniper Networks Junos OS on SRX Series and MX Series allows an unauthenticated network-based attacker to cause an integrity impact in connected networks. If the SIP ALG is configured and a device receives a specifically malformed SIP packet, the device prevents this packet from being forwarded, but any subsequently received retransmissions of the same packet are forwarded as if they were valid. This issue affects Juniper Networks Junos OS on SRX Series and MX Series: * 20.4 versions prior to 20.4R3-S5; * 21.1 versions prior to 21.1R3-S4; * 21.2 versions prior to 21.2R3-S4; * 21.3 versions prior to 21.3R3-S3; * 21.4 versions prior to 21.4R3-S2; * 22.1 versions prior to 22.1R2-S2, 22.1R3; * 22.2 versions prior to 22.2R2-S1, 22.2R3; * 22.3 versions prior to 22.3R1-S2, 22.3R2. This issue doesn't not affected releases prior to 20.4R1. Una vulnerabilidad de Verificación Inadecuada de Condiciones Inusuales o Excepcionales en SIP ALG de Juniper Networks Junos OS en las series SRX y MX permite que un atacante basado en red no autenticado cause un impacto en la integridad de las redes conectadas. Si SIP ALG está configurado y un dispositivo recibe un paquete SIP específicamente mal formado, el dispositivo impide que este paquete se reenvíe, pero cualquier retransmisión recibida posteriormente del mismo paquete se reenvía como si fuera válida. Este problema afecta a Juniper Networks Junos OS en las series SRX y MX: * Versiones 20.4 anteriores a 20.4R3-S5; * Versiones 21.1 anteriores a 21.1R3-S4; * Versiones 21.2 anteriores a 21.2R3-S4; * Versiones 21.3 anteriores a 21.3R3-S3; * Versiones 21.4 anteriores a 21.4R3-S2; * Versiones 22.1 anteriores a 22.1R2-S2, 22.1R3; * Versiones 22.2 anteriores a 22.2R2-S1, 22.2R3; * Versiones 22.3 anteriores a 22.3R1-S2, 22.3R2.

https://notcve.org/view.php?id=CVE-2023-44196
An Improper Check for Unusual or Exceptional Conditions in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS Evolved on PTX10003 Series allows an unauthenticated adjacent attacker to cause an impact to the integrity of the system. When specific transit MPLS packets are received by the PFE, these packets are internally forwarded to the RE. This issue is a prerequisite for CVE-2023-44195. This issue affects Juniper Networks Junos OS Evolved: * All versions prior to 20.4R3-S8-EVO; * 21.1-EVO version 21.1R1-EVO and later; * 21.2-EVO versions prior to 21.2R3-S6-EVO; * 21.3-EVO version 21.3R1-EVO and later; * 21.4-EVO versions prior to 21.4R3-S3-EVO; * 22.1-EVO versions prior to 22.1R3-S4-EVO; * 22.2-EVO versions prior to 22.2R3-S3-EVO; * 22.3-EVO versions prior to 22.3R2-S2-EVO, 22.3R3-EVO; * 22.4-EVO versions prior to 22.4R2-EVO.

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.

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 •
