CVSS: 8.2EPSS: 0%CPEs: 4EXPL: 0CVE-2024-30401 – Junos OS: MX Series and EX9200-15C: Stack-based buffer overflow in aftman
https://notcve.org/view.php?id=CVE-2024-30401
An Out-of-bounds Read vulnerability in the advanced forwarding management process aftman of Juniper Networks Junos OS on MX Series with MPC10E, MPC11, MX10K-LC9600 line cards, MX304, and EX9200-15C, may allow an attacker to exploit a stack-based buffer overflow, leading to a reboot of the FPC. Through code review, it was determined that the interface definition code for aftman could read beyond a buffer boundary, leading to a stack-based buffer overflow. This issue affects Junos OS on MX Series and EX9200-15C: * from 21.2 before 21.2R3-S1, * from 21.4 before 21.4R3, * from 22.1 before 22.1R2, * from 22.2 before 22.2R2; This issue does not affect: * versions of Junos OS prior to 20.3R1; * any version of Junos OS 20.4. Una vulnerabilidad de lectura fuera de los límites en el proceso avanzado de gestión de reenvío de Juniper Networks Junos OS en la serie MX con tarjetas de línea MPC10E, MPC11, MX10K-LC9600, MX304 y EX9200-15C, puede permitir que un atacante aproveche un desbordamiento del búfer basado en la pila, lo que provocará un reinicio del FPC. A través de la revisión del código, se determinó que el código de definición de interfaz para aftman podía leer más allá del límite del búfer, lo que provocaba un desbordamiento del búfer basado en pila. Este problema afecta a Junos OS en la serie MX y EX9200-15C: * desde 21.2 antes de 21.2R3-S1, * desde 21.4 antes de 21.4R3, * desde 22.1 antes de 22.1R2, * desde 22.2 antes de 22.2R2; Este problema no afecta a: * versiones de Junos OS anteriores a 20.3R1; * cualquier versión de Junos OS 20.4. • https://supportportal.juniper.net/JSA79110 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N • CWE-125: Out-of-bounds Read •
CVSS: 8.7EPSS: 0%CPEs: 8EXPL: 0CVE-2024-30398 – Junos OS: SRX4600 Series - A high amount of specific traffic causes packet drops and an eventual PFE crash
https://notcve.org/view.php?id=CVE-2024-30398
An Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). When a high amount of specific traffic is received on a SRX4600 device, due to an error in internal packet handling, a consistent rise in CPU memory utilization occurs. This results in packet drops in the traffic and eventually the PFE crashes. A manual reboot of the PFE will be required to restore the device to original state. This issue affects Junos OS: * 21.2 before 21.2R3-S7, * 21.4 before 21.4R3-S6, * 22.1 before 22.1R3-S5, * 22.2 before 22.2R3-S3, * 22.3 before 22.3R3-S2, * 22.4 before 22.4R3, * 23.2 before 23.2R1-S2, 23.2R2. Una restricción inadecuada de operaciones dentro de los límites de una vulnerabilidad de búfer de memoria en el motor de reenvío de paquetes (PFE) de Juniper Networks Junos OS permite que un atacante no autenticado basado en la red provoque una denegación de servicio (DoS). Cuando se recibe una gran cantidad de tráfico específico en un dispositivo SRX4600, debido a un error en el manejo de paquetes internos, se produce un aumento constante en la utilización de la memoria de la CPU. • https://supportportal.juniper.net/JSA79176 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-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2024-30397
An Improper Check for Unusual or Exceptional Conditions vulnerability in the the Public Key Infrastructure daemon (pkid) of Juniper Networks Junos OS allows an unauthenticated networked attacker to cause Denial of Service (DoS). The pkid is responsible for the certificate verification. Upon a failed verification, the pkid uses all CPU resources and becomes unresponsive to future verification attempts. This means that all subsequent VPN negotiations depending on certificate verification will fail. This CPU utilization of pkid can be checked using this command: root@srx> show system processes extensive | match pkid xxxxx root 103 0 846M 136M CPU1 1 569:00 100.00% pkid This issue affects: Juniper Networks Junos OS * All versions prior to 20.4R3-S10; * 21.2 versions prior to 21.2R3-S7; * 21.4 versions prior to 21.4R3-S5; * 22.1 versions prior to 22.1R3-S4; * 22.2 versions prior to 22.2R3-S3; * 22.3 versions prior to 22.3R3-S1; * 22.4 versions prior to 22.4R3; * 23.2 versions prior to 23.2R1-S2, 23.2R2. Una vulnerabilidad de verificación inadecuada de condiciones inusuales o excepcionales en el daemon de infraestructura de clave pública (pkid) de Juniper Networks Junos OS permite que un atacante en red no autenticado provoque una denegación de servicio (DoS).

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 •
