A Missing Release of Memory after Effective Lifetime vulnerability in Routing Protocol Daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause an rpd crash, leading to Denial of Service (DoS). On all Junos OS and Junos OS Evolved platforms, when traffic engineering is enabled for OSPF or ISIS, and a link flaps, a patroot memory leak is observed. This memory leak, over time, will lead to an rpd crash and restart. The memory usage can be monitored using the below command. user@host> show task memory detail | match patroot This issue affects: Juniper Networks Junos OS * All versions earlier than 21.2R3-S3; * 21.3 versions earlier than 21.3R3-S5; * 21.4 versions earlier than 21.4R3-S3; * 22.1 versions earlier than 22.1R3; * 22.2 versions earlier than 22.2R3.

CVSS: 7.5EPSS: 0%CPEs: 68EXPL: 0CVE-2024-21612 – Junos OS Evolved: Specific TCP traffic causes OFP core and restart of RE
https://notcve.org/view.php?id=CVE-2024-21612
An Improper Handling of Syntactically Invalid Structure vulnerability in Object Flooding Protocol (OFP) service of Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). On all Junos OS Evolved platforms, when specific TCP packets are received on an open OFP port, the OFP crashes leading to a restart of Routine Engine (RE). Continuous receipt of these specific TCP packets will lead to a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS Evolved * All versions earlier than 21.2R3-S7-EVO; * 21.3 versions earlier than 21.3R3-S5-EVO ; * 21.4 versions earlier than 21.4R3-S5-EVO; * 22.1 versions earlier than 22.1R3-S4-EVO; * 22.2 versions earlier than 22.2R3-S3-EVO ; * 22.3 versions earlier than 22.3R3-EVO; * 22.4 versions earlier than 22.4R2-EVO, 22.4R3-EVO. Una vulnerabilidad de manejo inadecuado de una estructura sintácticamente no válida en el servicio Object Flooding Protocol (OFP) de Juniper Networks Junos OS Evolved permite que un atacante no autenticado basado en la red provoque una denegación de servicio (DoS). En todas las plataformas Junos OS Evolved, cuando se reciben paquetes TCP específicos en un puerto OFP abierto, el OFP falla y se reinicia el Routine Engine (RE). La recepción continua de estos paquetes TCP específicos dará lugar a una condición sostenida de Denegación de Servicio (DoS). • https://supportportal.juniper.net/JSA75753 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:N • CWE-228: Improper Handling of Syntactically Invalid Structure •
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: 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 •
