CVSS: 7.1EPSS: 0%CPEs: 17EXPL: 0CVE-2024-39517 – Junos OS and Junos OS Evolved: Upon processing specific L2 traffic, rpd can hang in devices with EVPN/VXLAN configured
https://notcve.org/view.php?id=CVE-2024-39517
An Improper Check for Unusual or Exceptional Conditions vulnerability in the Layer 2 Address Learning Daemon (l2ald) on Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause Denial of Service (DoS). In an EVPN/VXLAN scenario, when a high amount specific Layer 2 packets are processed by the device, it can cause the Routing Protocol Daemon (rpd) to utilize all CPU resources which causes the device to hang. A manual restart of the rpd is required to restore services. This issue affects both IPv4 and IPv6 implementations. This issue affects Junos OS: All versions earlier than 21.4R3-S7; 22.1 versions earlier than 22.1R3-S5; 22.2 versions earlier than 22.2R3-S3; 22.3 versions earlier than 22.3R3-S3; 22.4 versions earlier than 22.4R3-S2; 23.2 versions earlier than 23.2R2; 23.4 versions earlier than 23.4R1-S1. Junos OS Evolved: All versions earlier than 21.4R3-S7-EVO; 22.1-EVO versions earlier than 22.1R3-S5-EVO; 22.2-EVO versions earlier than 22.2R3-S3-EVO; 22.3-EVO versions earlier than 22.3R3-S3-EVO; 22.4-EVO versions earlier than 22.4R3-S2-EVO; 23.2-EVO versions earlier than 23.2R2-EVO; 23.4-EVO versions earlier than 23.4R1-S1-EVO, 23.4R2-EVO. Una vulnerabilidad de comprobación inadecuada de las condiciones inusuales o excepcionales en el daemon de aprendizaje de direcciones de capa 2 (l2ald) en Juniper Networks Junos OS y Junos OS Evolved permite que un atacante adyacente no autenticado provoque una denegación de servicio (DoS). En un escenario EVPN/VXLAN, cuando el dispositivo procesa una gran cantidad de paquetes específicos de Capa 2, puede provocar que el daemon de protocolo de enrutamiento (rpd) utilice todos los recursos de la CPU, lo que provoca que el dispositivo se cuelgue. Es necesario reiniciar manualmente el rpd para restaurar los servicios. • https://supportportal.juniper.net/JSA79175 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVSS: 7.1EPSS: 0%CPEs: 14EXPL: 0CVE-2024-39514 – Junos OS and Junos OS Evolved: Receiving specific traffic on devices with EVPN-VPWS with IGMP-snooping enabled will cause the rpd to crash
https://notcve.org/view.php?id=CVE-2024-39514
An Improper Check or Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS). An attacker can send specific traffic to the device, which causes the rpd to crash and restart. Continued receipt of this traffic will result in a sustained DoS condition. This issue only affects devices with an EVPN-VPWS instance with IGMP-snooping enabled. This issue affects Junos OS: * All versions before 20.4R3-S10, * from 21.4 before 21.4R3-S6, * from 22.1 before 22.1R3-S5, * from 22.2 before 22.2R3-S3, * from 22.3 before 22.3R3-S2, * from 22.4 before 22.4R3, * from 23.2 before 23.2R2; Junos OS Evolved: * All versions before 20.4R3-S10-EVO, * from 21.4-EVO before 21.4R3-S6-EVO, * from 22.1-EVO before 22.1R3-S5-EVO, * from 22.2-EVO before 22.2R3-S3-EVO, * from 22.3-EVO before 22.3R3-S2-EVO, * from 22.4-EVO before 22.4R3-EVO, * from 23.2-EVO before 23.2R2-EVO. Una vulnerabilidad de verificación o manejo inadecuado de condiciones excepcionales en el demonio de protocolo de enrutamiento (rpd) de Juniper Networks Junos y Junos OS Evolved permite que un atacante adyacente no autenticado provoque una denegación de servicio (DoS). Un atacante puede enviar tráfico específico al dispositivo, lo que provoca que el rpd falle y se reinicie. La recepción continua de este tráfico dará como resultado una condición DoS sostenida. • https://supportportal.juniper.net/JSA82980 • CWE-703: Improper Check or Handling of Exceptional Conditions •
CVSS: 6.8EPSS: 0%CPEs: 8EXPL: 0CVE-2024-39511 – Junos OS: The 802.1X Authentication Daemon crashes on running a specific command
https://notcve.org/view.php?id=CVE-2024-39511
An Improper Input Validation vulnerability in the 802.1X Authentication (dot1x) Daemon of Juniper Networks Junos OS allows a local, low-privileged attacker with access to the CLI to cause a Denial of Service (DoS). On running a specific operational dot1x command, the dot1x daemon crashes. An attacker can cause a sustained DoS condition by running this command repeatedly. When the crash occurs, the authentication status of any 802.1x clients is cleared, and any authorized dot1x port becomes unauthorized. The client cannot re-authenticate until the dot1x daemon restarts. This issue affects Junos OS: * All versions before 20.4R3-S10; * 21.2 versions before 21.2R3-S7; * 21.4 versions before 21.4R3-S6; * 22.1 versions before 22.1R3-S5; * 22.2 versions before 22.2R3-S3; * 22.3 versions before 22.3R3-S2; * 22.4 versions before 22.4R3-S1; * 23.2 versions before 23.2R2. Una vulnerabilidad de validación de entrada incorrecta en el demonio de autenticación 802.1X (dot1x) de Juniper Networks Junos OS permite que un atacante local con pocos privilegios y acceso a la CLI provoque una denegación de servicio (DoS). Al ejecutar un comando operativo dot1x específico, el demonio dot1x falla. • https://supportportal.juniper.net/JSA82976 • CWE-20: Improper Input Validation •
CVSS: 8.8EPSS: 0%CPEs: 8EXPL: 0CVE-2024-39565 – Junos OS: J-Web: An unauthenticated, network-based attacker can perform XPATH injection attack against a device.
https://notcve.org/view.php?id=CVE-2024-39565
An Improper Neutralization of Data within XPath Expressions ('XPath Injection') vulnerability in J-Web shipped with Juniper Networks Junos OS allows an unauthenticated, network-based attacker to execute remote commands on the target device. While an administrator is logged into a J-Web session or has previously logged in and subsequently logged out of their J-Web session, the attacker can arbitrarily execute commands on the target device with the other user's credentials. In the worst case, the attacker will have full control over the device. This issue affects Junos OS: * All versions before 21.2R3-S8, * from 21.4 before 21.4R3-S7, * from 22.2 before 22.2R3-S4, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S2, * from 23.2 before 23.2R2, * from 23.4 before 23.4R1-S1, 23.4R2. Una vulnerabilidad de neutralización inadecuada de datos dentro de expresiones XPath ('inyección XPath') en J-Web incluido con Juniper Networks Junos OS permite que un atacante basado en red no autenticado ejecute comandos remotos en el dispositivo objetivo. Mientras un administrador inicia sesión en una sesión de J-Web o ha iniciado sesión previamente y posteriormente ha cerrado sesión en su sesión de J-Web, el atacante puede ejecutar comandos arbitrariamente en el dispositivo de destino con las credenciales del otro usuario. En el peor de los casos, el atacante tendrá control total sobre el dispositivo. • https://support.juniper.net/support/downloads/?p=283 https://supportportal.juniper.net/JSA83023 https://www.first.org/cvss/calculator/v4-0#CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/AU:Y/R:I/V:C/RE:L/U:Amber • CWE-643: Improper Neutralization of Data within XPath Expressions ('XPath Injection') •
CVSS: 6.9EPSS: 0%CPEs: 9EXPL: 0CVE-2024-39561 – Junos OS: SRX4600, SRX5000 Series: TCP packets with SYN/FIN or SYN/RST are transferred after enabling no-syn-check with Express Path
https://notcve.org/view.php?id=CVE-2024-39561
An Improper Check for Unusual or Exceptional Conditions vulnerability in the flow daemon (flowd) of Juniper Networks Junos OS on SRX4600 and SRX5000 Series allows an attacker to send TCP packets with SYN/FIN or SYN/RST flags, bypassing the expected blocking of these packets. A TCP packet with SYN/FIN or SYN/RST should be dropped in flowd. However, when no-syn-check and Express Path are enabled, these TCP packets are unexpectedly transferred to the downstream network. This issue affects Junos OS on SRX4600 and SRX5000 Series: * All versions before 21.2R3-S8, * from 21.4 before 21.4R3-S7, * from 22.1 before 22.1R3-S6, * from 22.2 before 22.2R3-S4, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S2, * from 23.2 before 23.2R2, * from 23.4 before 23.4R1-S1, 23.4R2. Una vulnerabilidad de verificación inadecuada de condiciones inusuales o excepcionales en el demonio de flujo (flowd) de Juniper Networks Junos OS en las series SRX4600 y SRX5000 permite a un atacante enviar paquetes TCP con indicadores SYN/FIN o SYN/RST, evitando el bloqueo esperado de estos paquetes. . Un paquete TCP con SYN/FIN o SYN/RST debe descartarse en flowd. Sin embargo, cuando no-syn-check y Express Path están habilitados, estos paquetes TCP se transfieren inesperadamente a la red descendente. • https://supportportal.juniper.net/JSA83021 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
