CVSS: 8.7EPSS: 0%CPEs: 20EXPL: 0CVE-2024-21598 – Junos OS and Junos OS Evolved: A malformed BGP tunnel encapsulation attribute will lead to an rpd crash
https://notcve.org/view.php?id=CVE-2024-21598
An Improper Validation of Syntactic Correctness of Input vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). If a BGP update is received over an established BGP session which contains a tunnel encapsulation attribute with a specifically malformed TLV, rpd will crash and restart. This issue affects Juniper Networks Junos OS: * 20.4 versions 20.4R1 and later versions earlier than 20.4R3-S9; * 21.2 versions earlier than 21.2R3-S7; * 21.3 versions earlier than 21.3R3-S5; * 21.4 versions earlier than 21.4R3-S5; * 22.1 versions earlier than 22.1R3-S4; * 22.2 versions earlier than 22.2R3-S3; * 22.3 versions earlier than 22.3R3-S1; * 22.4 versions earlier than 22.4R3; * 23.2 versions earlier than 23.2R1-S2, 23.2R2; Junos OS Evolved: * 20.4-EVO versions 20.4R1-EVO and later versions earlier than 20.4R3-S9-EVO; * 21.2-EVO versions earlier than 21.2R3-S7-EVO; * 21.3-EVO versions earlier than 21.3R3-S5-EVO; * 21.4-EVO versions earlier than 21.4R3-S5-EVO; * 22.1-EVO versions earlier than 22.1R3-S4-EVO; * 22.2-EVO versions earlier than 22.2R3-S3-EVO; * 22.3-EVO versions earlier than 22.3R3-S1-EVO; * 22.4-EVO versions earlier than 22.4R3-EVO; * 23.2-EVO versions earlier than 23.2R1-S2-EVO, 23.2R2-EVO; This issue does not affect Juniper Networks * Junos OS versions earlier than 20.4R1; * Junos OS Evolved versions earlier than 20.4R1-EVO. This is a related but separate issue than the one described in JSA79095. Una validación inadecuada de la vulnerabilidad de corrección sintáctica de entrada en el daemon de protocolo de enrutamiento (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante no autenticado basado en red provoque una denegación de servicio (DoS). Si se recibe una actualización de BGP a través de una sesión BGP establecida que contiene un atributo de encapsulación de túnel con un TLV específicamente mal formado, rpd fallará y se reiniciará. Este problema afecta a Juniper Networks Junos OS: * 20.4 versiones 20.4R1 y versiones posteriores anteriores a 20.4R3-S9; * Versiones 21.2 anteriores a 21.2R3-S7; * Versiones 21.3 anteriores a 21.3R3-S5; * Versiones 21.4 anteriores a 21.4R3-S5; * Versiones 22.1 anteriores a 22.1R3-S4; * Versiones 22.2 anteriores a 22.2R3-S3; * Versiones 22.3 anteriores a 22.3R3-S1; * Versiones 22.4 anteriores a 22.4R3; * Versiones 23.2 anteriores a 23.2R1-S2, 23.2R2; Junos OS Evolved: * 20.4-EVO versiones 20.4R1-EVO y versiones posteriores anteriores a 20.4R3-S9-EVO; * Versiones 21.2-EVO anteriores a 21.2R3-S7-EVO; * Versiones 21.3-EVO anteriores a 21.3R3-S5-EVO; * Versiones 21.4-EVO anteriores a 21.4R3-S5-EVO; * Versiones 22.1-EVO anteriores a 22.1R3-S4-EVO; * Versiones 22.2-EVO anteriores a 22.2R3-S3-EVO; * Versiones 22.3-EVO anteriores a 22.3R3-S1-EVO; * Versiones 22.4-EVO anteriores a 22.4R3-EVO; * Versiones 23.2-EVO anteriores a 23.2R1-S2-EVO, 23.2R2-EVO; Este problema no afecta a Juniper Networks * versiones de Junos OS anteriores a 20.4R1; * Versiones de Junos OS Evolved anteriores a 20.4R1-EVO.

CVSS: 7.1EPSS: 0%CPEs: 8EXPL: 0CVE-2024-21593 – Junos OS: MX Series with MPC10, MPC11, LC9600, and MX304: A specific MPLS packet will cause a PFE crash
https://notcve.org/view.php?id=CVE-2024-21593
An Improper Check or Handling of Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS). If an attacker sends a specific MPLS packet, which upon processing, causes an internal loop, that leads to a PFE crash and restart. Continued receipt of these packets leads to a sustained Denial of Service (DoS) condition. Circuit cross-connect (CCC) needs to be configured on the device for it to be affected by this issue. This issue only affects MX Series with MPC10, MPC11, LC9600, and MX304. This issue affects: Juniper Networks Junos OS 21.4 versions from 21.4R3 earlier than 21.4R3-S5; 22.2 versions from 22.2R2 earlier than 22.2R3-S2; 22.3 versions from 22.3R1 earlier than 22.3R2-S2; 22.3 versions from 22.3R3 earlier than 22.3R3-S1 22.4 versions from 22.4R1 earlier than 22.4R2-S2, 22.4R3; 23.2 versions earlier than 23.2R1-S1, 23.2R2. Una vulnerabilidad de verificación o manejo inadecuado de condiciones excepcionales en el motor de reenvío de paquetes (PFE) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante adyacente no autenticado provoque una denegación de servicio (DoS). Si un atacante envía un paquete MPLS específico, que al procesarse, provoca un bucle interno, lo que provoca un bloqueo y reinicio del PFE. La recepción continua de estos paquetes conduce a una condición sostenida de Denegación de Servicio (DoS). • https://supportportal.juniper.net/JSA75732 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L • CWE-703: Improper Check or Handling of Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2024-21590
An Improper Input Validation vulnerability in Juniper Tunnel Driver (jtd) and ICMP module of Juniper Networks Junos OS Evolved allows an unauthenticated attacker within the MPLS administrative domain to send specifically crafted packets to the Routing Engine (RE) to cause a Denial of Service (DoS). When specifically crafted transit MPLS IPv4 packets are received by the Packet Forwarding Engine (PFE), these packets are internally forwarded to the RE. Continued receipt of these packets may create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS: * All versions before 21.2R3-S8-EVO; * from 21.4-EVO before 21.4R3-S6-EVO; * from 22.2-EVO before 22.2R3-S4-EVO; * from 22.3-EVO before 22.3R3-S3-EVO; * from 22.4-EVO before 22.4R3-EVO; * from 23.2-EVO before 23.2R2-EVO. * from 23.4-EVO before 23.4R1-S1-EVO. Una vulnerabilidad de validación de entrada incorrecta en Juniper Tunnel Driver (jtd) y el módulo ICMP de Juniper Networks Junos OS Evolved permite a un atacante no autenticado dentro del dominio administrativo MPLS enviar paquetes específicamente manipulados al motor de enrutamiento (RE) para provocar una denegación de servicio (DoS). ). Cuando el motor de reenvío de paquetes (PFE) recibe paquetes MPLS IPv4 de tránsito específicamente manipulados, estos paquetes se reenvían internamente al RE.
