An Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in J-Web of Juniper Networks Junos OS on SRX Series and EX Series allows an attacker to construct a URL that when visited by another user enables the attacker to execute commands with the target's permissions, including an administrator. A specific invocation of the emit_debug_note method in webauth_operation.php will echo back the data it receives. This issue affects Juniper Networks Junos OS on SRX Series and EX Series: * All versions earlier than 20.4R3-S10; * 21.2 versions earlier than 21.2R3-S8; * 21.4 versions earlier than 21.4R3-S6; * 22.1 versions earlier than 22.1R3-S5; * 22.2 versions earlier than 22.2R3-S3; * 22.3 versions earlier than 22.3R3-S2; * 22.4 versions earlier than 22.4R3-S1; * 23.2 versions earlier than 23.2R2; * 23.4 versions earlier than 23.4R2.

A Missing Authentication for Critical Function vulnerability combined with a Generation of Error Message Containing Sensitive Information vulnerability in J-Web of Juniper Networks Junos OS on SRX Series and EX Series allows an unauthenticated, network-based attacker to access sensitive system information. When a user logs in, a temporary file which contains the configuration of the device (as visible to that user) is created in the /cache folder. An unauthenticated attacker can then attempt to access such a file by sending a specific request to the device trying to guess the name of such a file. Successful exploitation will reveal configuration information. This issue affects Juniper Networks Junos OS on SRX Series and EX Series: * All versions earlier than 20.4R3-S9; * 21.2 versions earlier than 21.2R3-S7; * 21.3 versions earlier than 21.3R3-S5; * 21.4 versions earlier than 21.4R3-S6; * 22.1 versions earlier than 22.1R3-S5; * 22.2 versions earlier than 22.2R3-S3; * 22.3 versions earlier than 22.3R3-S2; * 22.4 versions earlier than 22.4R3; * 23.2 versions earlier than 23.2R1-S2, 23.2R2. Una vulnerabilidad de autenticación faltante para función crítica combinada con una vulnerabilidad de generación de mensaje de error que contiene información confidencial en J-Web de Juniper Networks Junos OS en las series SRX y EX permite que un atacante basado en red no autenticado acceda a información confidencial del sistema. Cuando un usuario inicia sesión, se crea un archivo temporal que contiene la configuración del dispositivo (como es visible para ese usuario) en la carpeta /cache. • https://supportportal.juniper.net/JSA76390 • CWE-209: Generation of Error Message Containing Sensitive Information CWE-306: Missing Authentication for Critical Function •

An Allocation of Resources Without Limits or Throttling vulnerability in Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause Denial of Service (DoS). On all Junos OS QFX5000 Series and EX4000 Series platforms, when a high number of VLANs are configured, a specific DHCP packet will cause PFE hogging which will lead to dropping of socket connections. This issue affects: Juniper Networks Junos OS on QFX5000 Series and EX4000 Series * 21.1 versions prior to 21.1R3-S5; * 21.2 versions prior to 21.2R3-S5; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R3-S4; * 22.1 versions prior to 22.1R3-S3; * 22.2 versions prior to 22.2R3-S1; * 22.3 versions prior to 22.3R2-S2, 22.3R3; * 22.4 versions prior to 22.4R2. This issue does not affect Juniper Networks Junos OS versions prior to 21.1R1 Una vulnerabilidad de asignación de recursos sin límites ni limitación en Juniper Networks Junos OS permite que un atacante no autenticado basado en la red provoque una Denegación de Servicio (DoS). En todas las plataformas Junos OS QFX5000 Series y EX4000 Series, cuando se configura una gran cantidad de VLAN, un paquete DHCP específico provocará un acaparamiento de PFE, lo que provocará la caída de las conexiones del socket. Este problema afecta a: Juniper Networks Junos OS en las series QFX5000 y EX4000 * versiones 21.1 anteriores a 21.1R3-S5; * 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-S3; * Versiones 22.2 anteriores a 22.2R3-S1; * Versiones 22.3 anteriores a 22.3R2-S2, 22.3R3; * Versiones 22.4 anteriores a 22.4R2.

An Improper Input Validation vulnerability in the VxLAN packet forwarding engine (PFE) of Juniper Networks Junos OS on QFX5000 Series, EX4600 Series devices allows an unauthenticated, adjacent attacker, sending two or more genuine packets in the same VxLAN topology to possibly cause a DMA memory leak to occur under various specific operational conditions. The scenario described here is the worst-case scenario. There are other scenarios that require operator action to occur. An indicator of compromise may be seen when multiple devices indicate that FPC0 has gone missing when issuing a show chassis fpc command for about 10 to 20 minutes, and a number of interfaces have also gone missing. Use the following command to determine if FPC0 has gone missing from the device. show chassis fpc detail This issue affects: Juniper Networks Junos OS on QFX5000 Series, EX4600 Series: * 18.4 version 18.4R2 and later versions prior to 20.4R3-S8; * 21.1 version 21.1R1 and later versions prior to 21.2R3-S6; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R3-S4; * 22.1 versions prior to 22.1R3-S3; * 22.2 versions prior to 22.2R3-S1; * 22.3 versions prior to 22.3R2-S2, 22.3R3; * 22.4 versions prior to 22.4R2. Una vulnerabilidad de validación de entrada incorrecta en Packet Forwarding Engine (PFE) VxLAN de Juniper Networks Junos OS en dispositivos de las series QFX5000 y EX4600 permite que un atacante adyacente no autenticado envíe dos o más paquetes genuinos en la misma topología VxLAN para causar posiblemente una memoria DMA que se produzca una fuga en diversas condiciones operativas específicas. El escenario descrito aquí es el peor de los casos. • https://supportportal.juniper.net/JSA73148 https://www.juniper.net/documentation/us/en/software/junos/evpn-vxlan/topics/topic-map/sdn-vxlan.html https://www.juniper.net/documentation/us/en/software/junos/multicast-l2/topics/topic-map/redundant-trunk-groups.html • CWE-20: Improper Input Validation CWE-401: Missing Release of Memory after Effective Lifetime •

A Missing Authentication for Critical Function vulnerability in Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause limited impact to the file system integrity. With a specific request to webauth_operation.php that doesn't require authentication, an attacker is able to upload and download arbitrary files via J-Web, leading to a loss of integrity or confidentiality, which may allow chaining to other vulnerabilities. This issue affects Juniper Networks Junos OS on SRX Series: * 21.2 versions prior to 21.2R3-S8; * 21.4 versions prior to 21.4R3-S6; * 22.1 versions prior to 22.1R3-S5; * 22.2 versions prior to 22.2R3-S3; * 22.3 versions prior to 22.3R3-S2; * 22.4 versions prior to 22,4R2-S2, 22.4R3; * 23.2 versions prior to 23.2R1-S2, 23.2R2. Una vulnerabilidad de autenticación faltante para funciones críticas en Juniper Networks Junos OS en la serie SRX permite que un atacante basado en red no autenticado cause un impacto limitado en la integridad del sistema de archivos. Con una solicitud específica a webauth_operation.php que no requiere autenticación, un atacante puede cargar archivos arbitrarios a través de J-Web, lo que provoca una pérdida de integridad de una determinada parte del sistema de archivos, lo que puede permitir el encadenamiento a otras vulnerabilidades. . Este problema afecta a Juniper Networks Junos OS en la serie SRX: * Versiones 22.4 anteriores a 22,4R2-S2, 22.4R3; * Versiones 23.2 anteriores a 23.2R2. Juniper Junos OS on SRX Series contains a missing authentication for critical function vulnerability that allows an unauthenticated, network-based attacker to cause limited impact to the file system integrity. • https://supportportal.juniper.net/JSA72300 • CWE-306: Missing Authentication for Critical Function •
