An Improper Check for Unusual or Exceptional Conditions vulnerability in the packetIO daemon of Juniper Networks Junos OS Evolved on PTX10003, PTX10004, and PTX10008 allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). Continued receipt of these crafted packets will cause a sustained Denial of Service condition. This issue affects Juniper Networks Junos OS Evolved all versions prior to 20.4R2-S3-EVO on PTX10003, PTX10004, and PTX10008. This issue does not affect: Juniper Networks Junos OS Evolved versions 21.1R1-EVO and above; Juniper Networks Junos OS. Una vulnerabilidad de Comprobación Inapropiada de Condiciones Inusuales o Excepcionales en el demonio packetIO de Juniper Networks Junos OS Evolved en PTX10003, PTX10004 y PTX10008 permite a un atacante no autenticado basado en la red causar una Denegación de Servicio (DoS). • https://kb.juniper.net/JSA69505 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVSS: 5.5EPSS: 0%CPEs: 30EXPL: 0CVE-2022-22193 – Junos OS and Junos OS Evolved: In a BGP rib-sharding scenario when a certain CLI command is executed the rpd process might crash
https://notcve.org/view.php?id=CVE-2022-22193
An Improper Handling of Unexpected Data Type vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a locally authenticated attacker with low privileges to cause a Denial of Service (DoS). Continued execution of this command might cause a sustained Denial of Service condition. If BGP rib sharding is configured and a certain CLI command is executed the rpd process can crash. During the rpd crash and restart, the routing protocols might be impacted and traffic disruption might be seen due to the loss of routing information. This issue affects: Juniper Networks Junos OS 20.3 versions prior to 20.3R3-S1; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R2. • https://kb.juniper.net/JSA69503 • CWE-241: Improper Handling of Unexpected Data Type •
CVSS: 7.8EPSS: 0%CPEs: 23EXPL: 0CVE-2022-22183 – Junos OS Evolved: A remote attacker may cause a CPU Denial of Service by sending genuine traffic to a device on a specific IPv4 port.
https://notcve.org/view.php?id=CVE-2022-22183
An Improper Access Control vulnerability in Juniper Networks Junos OS Evolved allows a network-based unauthenticated attacker who is able to connect to a specific open IPv4 port, which in affected releases should otherwise be unreachable, to cause the CPU to consume all resources as more traffic is sent to the port to create a Denial of Service (DoS) condition. Continued receipt and processing of these packets will create a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS Evolved 20.4 versions prior to 20.4R3-S2-EVO; 21.1 versions prior to 21.1R3-S1-EVO; 21.2 versions prior to 21.2R3-EVO; 21.3 versions prior to 21.3R2-EVO; 21.4 versions prior to 21.4R2-EVO. This issue does not affect Junos OS. Una vulnerabilidad de Control de Acceso Inapropiado en Juniper Networks Junos OS Evolved permite que un atacante no autenticado basado en la red que sea capaz de conectarse a un puerto IPv4 abierto específico, que en las versiones afectadas debería ser inalcanzable de otro modo, cause que la CPU consuma todos los recursos a medida que es enviado más tráfico al puerto para crear una condición de Denegación de Servicio (DoS). • https://kb.juniper.net/JSA69516 • CWE-16: Configuration CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-284: Improper Access Control •
