CVSS: 7.1EPSS: 0%CPEs: 14EXPL: 0CVE-2024-39543 – Junos OS and Junos OS Evolved: Receipt of a large RPKI-RTR PDU packet can cause rpd to crash
https://notcve.org/view.php?id=CVE-2024-39543
A Buffer Copy without Checking Size of Input vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Juniper Networks Junos OS Evolved allows an unauthenticated, adjacent attacker to send specific RPKI-RTR packets resulting in a crash, creating a Denial of Service (DoS) condition. Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue affects Junos OS: * All versions before 21.2R3-S8, * from 21.4 before 21.4R3-S8, * 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-S1, * from 23.4 before 23.4R2. Junos OS Evolved: * All versions before 21.2R3-S8-EVO, * from 21.4 before 21.4R3-S8-EVO, * from 22.2 before 22.2R3-S4-EVO, * from 22.3 before 22.3R3-S3-EVO, * from 22.4 before 22.4R3-S2-EVO, * from 23.2 before 23.2R2-S1-EVO, * from 23.4 before 23.4R2-EVO. • https://supportportal.juniper.net/JSA83004 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2024-39541
An Improper Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS). When conflicting information (IP or ISO addresses) about a node is added to the Traffic Engineering (TE) database and then a subsequent operation attempts to process these, rpd will crash and restart. This issue affects: Junos OS: * 22.4 versions before 22.4R3-S1, * 23.2 versions before 23.2R2, * 23.4 versions before 23.4R1-S1, 23.4R2, This issue does not affect Junos OS versions earlier than 22.4R1. Junos OS Evolved: * 22.4-EVO versions before 22.4R3-S2-EVO, * 23.2-EVO versions before 23.2R2-EVO, * 23.4-EVO versions before 23.4R1-S1-EVO, 23.4R2-EVO, This issue does not affect Junos OS Evolved versions earlier than before 22.4R1. • https://supportportal.juniper.net/JSA83001 • CWE-755: Improper Handling of Exceptional Conditions •
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: 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 •
