An Incorrect Permission Assignment for Critical Resource vulnerability in a specific file of Juniper Networks Junos OS and Junos OS Evolved allows a local authenticated attacker to read configuration changes without having the permissions. When a user with the respective permissions commits a configuration change, a specific file is created. That file is readable even by users with no permissions to access the configuration. This can lead to privilege escalation as the user can read the password hash when a password change is being committed. This issue affects: Juniper Networks Junos OS * All versions prior to 20.4R3-S4; * 21.1 versions prior to 21.1R3-S4; * 21.2 versions prior to 21.2R3-S2; * 21.3 versions prior to 21.3R2-S2, 21.3R3-S1; * 21.4 versions prior to 21.4R2-S1, 21.4R3. Juniper Networks Junos OS Evolved * All versions prior to 20.4R3-S4-EVO; * 21.1 versions prior to 21.1R3-S2-EVO; * 21.2 versions prior to 21.2R3-S2-EVO; * 21.3 versions prior to 21.3R3-S1-EVO; * 21.4 versions prior to 21.4R2-S2-EVO. Una vulnerabilidad de asignación de permisos incorrecta para recursos críticos en un archivo específico de Juniper Networks Junos OS y Junos OS Evolved permite a un atacante autenticado local leer cambios de configuración sin tener los permisos. Cuando un usuario con los permisos respectivos realiza un cambio de configuración, se crea un archivo específico. • https://supprtportal.juniper.net/JSA73167 • CWE-732: Incorrect Permission Assignment for Critical Resource •

An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on MX Series allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). On Junos MX Series platforms with Precision Time Protocol (PTP) configured, a prolonged routing protocol churn can lead to an FPC crash and restart. This issue affects Juniper Networks Junos OS on MX Series: * All versions prior to 20.4R3-S4; * 21.1 version 21.1R1 and later versions; * 21.2 versions prior to 21.2R3-S2; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R3; * 22.1 versions prior to 22.1R3; * 22.2 versions prior to 22.2R1-S1, 22.2R2. Una vulnerabilidad de Verificación Inadecuada de Condiciones Inusuales o Excepcionales en Packet Forwarding Engine (PFE) de Juniper Networks Junos OS en la serie MX permite que un atacante no autenticado basado en la red provoque una Denegación de Servicio (DoS). En las plataformas Junos MX Series con Precision Time Protocol (PTP) configurado, una rotación prolongada del protocolo de enrutamiento puede provocar un bloqueo y reinicio del FPC. Este problema afecta a Juniper Networks Junos OS en la serie MX: * Todas las versiones anteriores a 20.4R3-S4; * 21.1 versión 21.1R1 y versiones posteriores; * Versiones 21.2 anteriores a 21.2R3-S2; * Versiones 21.3 anteriores a 21.3R3-S5; * Versiones 21.4 anteriores a 21.4R3; * Versiones 22.1 anteriores a 22.1R3; * Versiones 22.2 anteriores a 22.2R1-S1, 22.2R2. • https://supportportal.juniper.net/JSA73165 • CWE-754: Improper Check for Unusual or Exceptional Conditions •

An Improper Check for Unusual or Exceptional Conditions vulnerability in the SIP ALG of Juniper Networks Junos OS on SRX Series and MX Series allows an unauthenticated network-based attacker to cause an integrity impact in connected networks. If the SIP ALG is configured and a device receives a specifically malformed SIP packet, the device prevents this packet from being forwarded, but any subsequently received retransmissions of the same packet are forwarded as if they were valid. This issue affects Juniper Networks Junos OS on SRX Series and MX Series: * 20.4 versions prior to 20.4R3-S5; * 21.1 versions prior to 21.1R3-S4; * 21.2 versions prior to 21.2R3-S4; * 21.3 versions prior to 21.3R3-S3; * 21.4 versions prior to 21.4R3-S2; * 22.1 versions prior to 22.1R2-S2, 22.1R3; * 22.2 versions prior to 22.2R2-S1, 22.2R3; * 22.3 versions prior to 22.3R1-S2, 22.3R2. This issue doesn't not affected releases prior to 20.4R1. Una vulnerabilidad de Verificación Inadecuada de Condiciones Inusuales o Excepcionales en SIP ALG de Juniper Networks Junos OS en las series SRX y MX permite que un atacante basado en red no autenticado cause un impacto en la integridad de las redes conectadas. Si SIP ALG está configurado y un dispositivo recibe un paquete SIP específicamente mal formado, el dispositivo impide que este paquete se reenvíe, pero cualquier retransmisión recibida posteriormente del mismo paquete se reenvía como si fuera válida. Este problema afecta a Juniper Networks Junos OS en las series SRX y MX: * Versiones 20.4 anteriores a 20.4R3-S5; * Versiones 21.1 anteriores a 21.1R3-S4; * Versiones 21.2 anteriores a 21.2R3-S4; * Versiones 21.3 anteriores a 21.3R3-S3; * Versiones 21.4 anteriores a 21.4R3-S2; * Versiones 22.1 anteriores a 22.1R2-S2, 22.1R3; * Versiones 22.2 anteriores a 22.2R2-S1, 22.2R3; * Versiones 22.3 anteriores a 22.3R1-S2, 22.3R2. Este problema no afecta a las versiones anteriores a 20.4R1. • https://supportportal.juniper.net/JSA73164 • CWE-754: Improper Check for Unusual or Exceptional Conditions •

An Out-of-Bounds Write 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). On all Junos OS and Junos OS Evolved devices an rpd crash and restart can occur while processing BGP route updates received over an established BGP session. This specific issue is observed for BGP routes learned via a peer which is configured with a BGP import policy that has hundreds of terms matching IPv4 and/or IPv6 prefixes. This issue affects Juniper Networks Junos OS: * All versions prior to 20.4R3-S8; * 21.1 version 21.1R1 and later versions; * 21.2 versions prior to 21.2R3-S2; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R2-S1, 21.4R3-S5. This issue affects Juniper Networks Junos OS Evolved: * All versions prior to 20.4R3-S8-EVO; * 21.1-EVO version 21.1R1-EVO and later versions; * 21.2-EVO versions prior to 21.2R3-S2-EVO; * 21.3-EVO version 21.3R1-EVO and later versions; * 21.4-EVO versions prior to 21.4R2-S1-EVO, 21.4R3-S5-EVO. Una vulnerabilidad de Escritura Fuera de los Límites en el 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 todos los dispositivos Junos OS y Junos OS Evolved, se puede producir un bloqueo y reinicio de rpd mientras se procesan las actualizaciones de ruta BGP recibidas a través de una sesión BGP establecida. Este problema específico se observa para las rutas BGP aprendidas a través de un par que está configurado con una política de importación de BGP que tiene cientos de términos que coinciden con los prefijos IPv4 y/o IPv6. • https://supportportal.juniper.net/JSA73163 • CWE-787: Out-of-bounds Write •

An Incorrect Default Permissions vulnerability in Juniper Networks Junos OS allows an unauthenticated attacker with local access to the device to create a backdoor with root privileges. The issue is caused by improper directory permissions on a certain system directory, allowing an attacker with access to this directory to create a backdoor with root privileges. This issue affects Juniper Networks Junos OS: * All versions prior to 20.4R3-S5; * 21.1 versions prior to 21.1R3-S4; * 21.2 versions prior to 21.2R3-S4; * 21.3 versions prior to 21.3R3-S3; * 21.4 versions prior to 21.4R3-S1. Una vulnerabilidad de permisos predeterminados incorrectos en Juniper Networks Junos OS permite que un atacante no autenticado con acceso local al dispositivo cree un backdoor con privilegios de root. El problema se debe a permisos de directorio inadecuados en un determinado directorio del sistema, lo que permite a un atacante con acceso a este directorio crear un backdoor con privilegios de root. Este problema afecta a Juniper Networks Junos OS: * Todas las versiones anteriores a 20.4R3-S5; * Versiones 21.1 anteriores a 21.1R3-S4; * Versiones 21.2 anteriores a 21.2R3-S4; * Versiones 21.3 anteriores a 21.3R3-S3; * Versiones 21.4 anteriores a 21.4R3-S1. • https://supportportal.juniper.net/JSA73158 • CWE-276: Incorrect Default Permissions •
