CVSS: 7.5EPSS: 0%CPEs: 40EXPL: 0CVE-2024-21611 – Junos OS and Junos OS Evolved: In a jflow scenario continuous route churn will cause a memory leak and eventually an rpd crash
https://notcve.org/view.php?id=CVE-2024-21611
A Missing Release of Memory after Effective Lifetime vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). In a Juniper Flow Monitoring (jflow) scenario route churn that causes BGP next hops to be updated will cause a slow memory leak and eventually a crash and restart of rpd. Thread level memory utilization for the areas where the leak occurs can be checked using the below command: user@host> show task memory detail | match so_in so_in6 28 32 344450 11022400 344760 11032320 so_in 8 16 1841629 29466064 1841734 29467744 This issue affects: Junos OS * 21.4 versions earlier than 21.4R3; * 22.1 versions earlier than 22.1R3; * 22.2 versions earlier than 22.2R3. Junos OS Evolved * 21.4-EVO versions earlier than 21.4R3-EVO; * 22.1-EVO versions earlier than 22.1R3-EVO; * 22.2-EVO versions earlier than 22.2R3-EVO. This issue does not affect: Juniper Networks Junos OS versions earlier than 21.4R1. Juniper Networks Junos OS Evolved versions earlier than 21.4R1. Una vulnerabilidad de liberación de memoria faltante después de la vida útil efectiva en Routing Protocol Daemon (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante basado en red no autenticado provoque una denegación de servicio (DoS). En un escenario de Juniper Flow Monitoring (jflow), la rotación de rutas que hace que los siguientes saltos de BGP se actualicen provocará una pérdida de memoria lenta y, finalmente, un bloqueo y reinicio de rpd. La utilización de la memoria a nivel de subproceso para las áreas donde se produce la fuga se puede verificar usando el siguiente comando: user@host> show task memory detail | match so_in so_in6 28 32 344450 11022400 344760 11032320 so_in 8 16 1841629 29466064 1841734 29467744. Este problema afecta a: Junos OS * 21.4 versiones anteriores a 21.4R3; * Versiones 22.1 anteriores a 22.1R3; * Versiones 22.2 anteriores a 22.2R3. • https://supportportal.juniper.net/JSA75752 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-401: Missing Release of Memory after Effective Lifetime •
CVSS: 5.3EPSS: 0%CPEs: 110EXPL: 0CVE-2024-21607 – Junos OS: MX Series and EX9200 Series: If the "tcp-reset" option used in an IPv6 filter, matched packets are accepted instead of rejected
https://notcve.org/view.php?id=CVE-2024-21607
An Unsupported Feature in the UI vulnerability in Juniper Networks Junos OS on MX Series and EX9200 Series allows an unauthenticated, network-based attacker to cause partial impact to the integrity of the device. If the "tcp-reset" option is added to the "reject" action in an IPv6 filter which matches on "payload-protocol", packets are permitted instead of rejected. This happens because the payload-protocol match criteria is not supported in the kernel filter causing it to accept all packets without taking any other action. As a fix the payload-protocol match will be treated the same as a "next-header" match to avoid this filter bypass. This issue doesn't affect IPv4 firewall filters. This issue affects Juniper Networks Junos OS on MX Series and EX9200 Series: * All versions earlier than 20.4R3-S7; * 21.1 versions earlier than 21.1R3-S5; * 21.2 versions earlier than 21.2R3-S5; * 21.3 versions earlier than 21.3R3-S4; * 21.4 versions earlier than 21.4R3-S4; * 22.1 versions earlier than 22.1R3-S2; * 22.2 versions earlier than 22.2R3-S2; * 22.3 versions earlier than 22.3R2-S2, 22.3R3; * 22.4 versions earlier than 22.4R1-S2, 22.4R2-S2, 22.4R3. Una característica no compatible en la vulnerabilidad de la interfaz de usuario en Juniper Networks Junos OS en las series MX y EX9200 permite que un atacante no autenticado basado en la red cause un impacto parcial en la integridad del dispositivo. Si se agrega la opción "tcp-reset" a la acción "reject" en un filtro IPv6 que coincide con el "payload-protocol", los paquetes se permiten en lugar de rechazarse. • https://supportportal.juniper.net/JSA75748 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N • CWE-447: Unimplemented or Unsupported Feature in UI •

CVSS: 7.5EPSS: 0%CPEs: 46EXPL: 0CVE-2024-21604 – Junos OS Evolved: A high rate of specific traffic will cause a complete system outage
https://notcve.org/view.php?id=CVE-2024-21604
An Allocation of Resources Without Limits or Throttling vulnerability in the kernel of Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). If a high rate of specific valid packets are processed by the routing engine (RE) this will lead to a loss of connectivity of the RE with other components of the chassis and thereby a complete and persistent system outage. Please note that a carefully designed lo0 firewall filter will block or limit these packets which should prevent this issue from occurring. The following log messages can be seen when this issue occurs: <host> kernel: nf_conntrack: nf_conntrack: table full, dropping packet This issue affects Juniper Networks Junos OS Evolved: * All versions earlier than 20.4R3-S7-EVO; * 21.2R1-EVO and later versions; * 21.4-EVO versions earlier than 21.4R3-S5-EVO; * 22.1-EVO versions earlier than 22.1R3-S2-EVO; * 22.2-EVO versions earlier than 22.2R3-EVO; * 22.3-EVO versions earlier than 22.3R2-EVO; * 22.4-EVO versions earlier than 22.4R2-EVO. Una vulnerabilidad de asignación de recursos sin límites ni limitación en el kernel de Juniper Networks Junos OS Evolved permite que un atacante no autenticado basado en la red provoque una denegación de servicio (DoS). Si el motor de enrutamiento (RE) procesa una alta tasa de paquetes válidos específicos, esto provocará una pérdida de conectividad del RE con otros componentes del chasis y, por lo tanto, una interrupción completa y persistente del sistema. Tenga en cuenta que un filtro de firewall lo0 cuidadosamente diseñado bloqueará o limitará estos paquetes, lo que debería evitar que ocurra este problema. • https://supportportal.juniper.net/JSA75745 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-770: Allocation of Resources Without Limits or Throttling •
CVSS: 6.5EPSS: 0%CPEs: 62EXPL: 0CVE-2024-21603 – Junos OS: MX Series: Gathering statistics in a scaled SCU/DCU configuration will lead to a device crash
https://notcve.org/view.php?id=CVE-2024-21603
An Improper Check for Unusual or Exceptional Conditions vulnerability in the kernel of Juniper Network Junos OS on MX Series allows a network based attacker with low privileges to cause a denial of service. If a scaled configuration for Source class usage (SCU) / destination class usage (DCU) (more than 10 route classes) is present and the SCU/DCU statistics are gathered by executing specific SNMP requests or CLI commands, a 'vmcore' for the RE kernel will be seen which leads to a device restart. Continued exploitation of this issue will lead to a sustained DoS. This issue only affects MX Series devices with MPC10, MPC11 or LC9600, and MX304. No other MX Series devices are affected. This issue affects Juniper Networks Junos OS: * All versions earlier than 20.4R3-S9; * 21.2 versions earlier than 21.2R3-S6; * 21.3 versions earlier than 21.3R3-S5; * 21.4 versions earlier than 21.4R3; * 22.1 versions earlier than 22.1R3; * 22.2 versions earlier than 22.2R2; * 22.3 versions earlier than 22.3R2. Una vulnerabilidad de verificación inadecuada de condiciones inusuales o excepcionales en el kernel de Juniper Network Junos OS en la serie MX permite que un atacante basado en red con privilegios bajos provoque una denegación de servicio. Si está presente una configuración escalada para el uso de clase de origen (SCU)/uso de clase de destino (DCU) (más de 10 clases de ruta) y las estadísticas de SCU/DCU se recopilan mediante la ejecución de solicitudes SNMP específicas o comandos CLI, se creará un 'vmcore' para el Se verá el kernel RE, lo que provocará un reinicio del dispositivo. • https://supportportal.juniper.net/JSA75744 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L • CWE-754: Improper Check for Unusual or Exceptional Conditions •
