CVSS: 7.1EPSS: 0%CPEs: 16EXPL: 0CVE-2024-30386 – Junos OS and Junos OS Evolved: In a EVPN-VXLAN scenario state changes on adjacent systems can cause an l2ald process crash
https://notcve.org/view.php?id=CVE-2024-30386
A Use-After-Free vulnerability in the Layer 2 Address Learning Daemon (l2ald) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause l2ald to crash leading to a Denial-of-Service (DoS). In an EVPN-VXLAN scenario, when state updates are received and processed by the affected system, the correct order of some processing steps is not ensured, which can lead to an l2ald crash and restart. Whether the crash occurs depends on system internal timing which is outside the attackers control. This issue affects: Junos OS: * All versions before 20.4R3-S8, * 21.2 versions before 21.2R3-S6, * 21.3 versions before 21.3R3-S5, * 21.4 versions before 21.4R3-S4, * 22.1 versions before 22.1R3-S3, * 22.2 versions before 22.2R3-S1, * 22.3 versions before 22.3R3,, * 22.4 versions before 22.4R2; Junos OS Evolved: * All versions before 20.4R3-S8-EVO, * 21.2-EVO versions before 21.2R3-S6-EVO, * 21.3-EVO versions before 21.3R3-S5-EVO, * 21.4-EVO versions before 21.4R3-S4-EVO, * 22.1-EVO versions before 22.1R3-S3-EVO, * 22.2-EVO versions before 22.2R3-S1-EVO, * 22.3-EVO versions before 22.3R3-EVO, * 22.4-EVO versions before 22.4R2-EVO. Una vulnerabilidad de Use-After-Free en el daemon de aprendizaje de direcciones de capa 2 (l2ald) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante adyacente no autenticado provoque que l2ald falle, lo que provoca una denegación de servicio (DoS). En un escenario EVPN-VXLAN, cuando el sistema afectado recibe y procesa actualizaciones de estado, no se garantiza el orden correcto de algunos pasos de procesamiento, lo que puede provocar un bloqueo y reinicio de l2ald. Que se produzca el fallo depende de la sincronización interna del sistema, que está fuera del control de los atacantes. • http://supportportal.juniper.net/JSA79184 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-416: Use After Free •
CVSS: 7.1EPSS: 0%CPEs: 10EXPL: 0CVE-2024-30387 – Junos OS: ACX5448 & ACX710: Due to interface flaps the PFE process can crash
https://notcve.org/view.php?id=CVE-2024-30387
A Missing Synchronization vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on ACX5448 and ACX710 allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS). If an interface flaps while the system gathers statistics on that interface, two processes simultaneously access a shared resource which leads to a PFE crash and restart. This issue affects Junos OS: * All versions before 20.4R3-S9, * 21.2 versions before 21.2R3-S5, * 21.3 versions before 21.3R3-S5, * 21.4 versions before 21.4R3-S4, * 22.1 versions before 22.1R3-S2, * 22.2 versions before 22.2R3-S2, * 22.3 versions before 22.3R2-S2, 22.3R3, * 22.4 versions before 22.4R2. Una vulnerabilidad de falta de sincronización en el motor de reenvío de paquetes (PFE) de Juniper Networks Junos OS en ACX5448 y ACX710 permite que un atacante adyacente no autenticado provoque una denegación de servicio (DoS). Si una interfaz parpadea mientras el sistema recopila estadísticas sobre esa interfaz, dos procesos acceden simultáneamente a un recurso compartido, lo que provoca un bloqueo y reinicio del PFE. Este problema afecta a Junos OS: todas las versiones anteriores a 20.4R3-S9, versiones 21.2 anteriores a 21.2R3-S5, versiones 21.3 anteriores a 21.3R3-S5, versiones 21.4 anteriores a 21.4R3-S4, versiones 22.1 anteriores a 22.1R3-S2, versiones 22.2 anteriores a 22.2 R3-S2, versiones 22.3 anteriores a 22.3R2-S2, 22.3R3, versiones 22.4 anteriores a 22.4R2. • http://supportportal.juniper.net/JSA79187 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-820: Missing Synchronization •
CVSS: 7.1EPSS: 0%CPEs: 9EXPL: 0CVE-2024-30388 – Junos OS: QFX5000 Series and EX Series: Specific malformed LACP packets will cause flaps
https://notcve.org/view.php?id=CVE-2024-30388
An Improper Isolation or Compartmentalization vulnerability in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS on QFX5000 Series and EX Series allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS). If a specific malformed LACP packet is received by a QFX5000 Series, or an EX4400, EX4100 or EX4650 Series device, an LACP flap will occur resulting in traffic loss. This issue affects Junos OS on QFX5000 Series, and on EX4400, EX4100 or EX4650 Series: * 20.4 versions from 20.4R3-S4 before 20.4R3-S8, * 21.2 versions from 21.2R3-S2 before 21.2R3-S6, * 21.4 versions from 21.4R2 before 21.4R3-S4, * 22.1 versions from 22.1R2 before 22.1R3-S3, * 22.2 versions before 22.2R3-S1, * 22.3 versions before 22.3R2-S2, 22.3R3, * 22.4 versions before 22.4R2-S1, 22.4R3. Una vulnerabilidad de aislamiento o compartimentación incorrecta en el motor de reenvío de paquetes (pfe) de Juniper Networks Junos OS en las series QFX5000 y EX permite que un atacante adyacente no autenticado provoque una denegación de servicio (DoS). Si un paquete LACP específico con formato incorrecto es recibido por un dispositivo de la serie QFX5000 o un dispositivo de la serie EX4400, EX4100 o EX4650, se producirá una falla de LACP que provocará una pérdida de tráfico. Este problema afecta a Junos OS en la serie QFX5000 y en las series EX4400, EX4100 o EX4650: * versiones 20.4 desde 20.4R3-S4 antes de 20.4R3-S8, * versiones 21.2 desde 21.2R3-S2 antes de 21.2R3-S6, * versiones 21.4 de 21.4R2 anterior a 21.4R3-S4, * 22.1 versiones anteriores a 22.1R2 anterior a 22.1R3-S3, * 22.2 versiones anteriores a 22.2R3-S1, * 22.3 versiones anteriores a 22.3R2-S2, 22.3R3, * 22.4 versiones anteriores a 22.4R2-S1, 22.4R3. • http://supportportal.juniper.net/JSA79089 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-653: Improper Isolation or Compartmentalization •
CVSS: 8.7EPSS: 0%CPEs: 9EXPL: 0CVE-2024-30392 – Junos OS: MX Series with SPC3 and MS-MPC/-MIC: When URL filtering is enabled and a specific URL request is received a flowd crash occurs
https://notcve.org/view.php?id=CVE-2024-30392
A Stack-based Buffer Overflow vulnerability in Flow Processing Daemon (flowd) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause Denial of Service (DoS). On all Junos OS MX Series platforms with SPC3 and MS-MPC/-MIC, when URL filtering is enabled and a specific URL request is received and processed, flowd will crash and restart. Continuous reception of the specific URL request will lead to a sustained Denial of Service (DoS) condition. This issue affects: Junos OS: * all versions before 21.2R3-S6, * from 21.3 before 21.3R3-S5, * from 21.4 before 21.4R3-S5, * from 22.1 before 22.1R3-S3, * from 22.2 before 22.2R3-S1, * from 22.3 before 22.3R2-S2, 22.3R3, * from 22.4 before 22.4R2-S1, 22.4R3. Una vulnerabilidad de desbordamiento de búfer en la región stack de la memoria en Flow Processing Daemon (flowd) de Juniper Networks Junos OS permite que un atacante no autenticado basado en red provoque una denegación de servicio (DoS). En todas las plataformas Junos OS MX Series con SPC3 y MS-MPC/-MIC, cuando el filtrado de URL está habilitado y se recibe y procesa una solicitud de URL específica, el flujo se bloqueará y se reiniciará. La recepción continua de la solicitud de URL específica dará lugar a una condición sostenida de Denegación de Servicio (DoS). • https://supportportal.juniper.net/JSA79092 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L • CWE-121: Stack-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2024-30394
A Stack-based Buffer Overflow vulnerability in the Routing Protocol Daemon (RPD) component of Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause an rpd crash, leading to Denial of Service (DoS). On all Junos OS and Junos OS Evolved platforms, when EVPN is configured, and a specific EVPN type-5 route is received via BGP, rpd crashes and restarts. Continuous receipt of this specific route will lead to a sustained Denial of Service (DoS) condition. This issue affects: Junos OS: * all versions before 21.2R3-S7, * from 21.4 before 21.4R3-S5, * from 22.1 before 22.1R3-S4, * from 22.2 before 22.2R3-S2, * from 22.3 before 22.3R3-S1, * from 22.4 before 22.4R3, * from 23.2 before 23.2R2.
