CVSS: 7.5EPSS: 0%CPEs: 10EXPL: 0CVE-2022-22194 – Junos OS Evolved: PTX series: An attacker sending a crafted GRE packet will cause the PFE to restart
https://notcve.org/view.php?id=CVE-2022-22194
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: 6.5EPSS: 0%CPEs: 209EXPL: 0CVE-2022-22191 – Junos OS: EX4300: PFE Denial of Service (DoS) upon receipt of a flood of specific ARP traffic
https://notcve.org/view.php?id=CVE-2022-22191
A Denial of Service (DoS) vulnerability in the processing of a flood of specific ARP traffic in Juniper Networks Junos OS on the EX4300 switch, sent from the local broadcast domain, may allow an unauthenticated network-adjacent attacker to trigger a PFEMAN watchdog timeout, causing the Packet Forwarding Engine (PFE) to crash and restart. After the restart, transit traffic will be temporarily interrupted until the PFE is reprogrammed. In a virtual chassis (VC), the impacted Flexible PIC Concentrator (FPC) may split from the VC temporarily, and join back into the VC once the PFE restarts. Continued receipt and processing of these packets will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS on the EX4300: All versions prior to 15.1R7-S12; 18.4 versions prior to 18.4R2-S10, 18.4R3-S11; 19.1 versions prior to 19.1R3-S8; 19.2 versions prior to 19.2R1-S9, 19.2R3-S4; 19.3 versions prior to 19.3R3-S5; 19.4 versions prior to 19.4R2-S6, 19.4R3-S7; 20.1 versions prior to 20.1R3-S3; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S2; 20.4 versions prior to 20.4R3-S1; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R2-S1, 21.2R3; 21.3 versions prior to 21.3R1-S2, 21.3R2. • https://kb.juniper.net/JSA69502 • CWE-400: Uncontrolled Resource Consumption CWE-410: Insufficient Resource Pool •
CVSS: 7.2EPSS: 0%CPEs: 124EXPL: 0CVE-2022-22186 – Junos OS: EX4650 Series: Certain traffic received by the Junos OS device on the management interface may be forwarded to egress interfaces instead of discarded
https://notcve.org/view.php?id=CVE-2022-22186
Due to an Improper Initialization vulnerability in Juniper Networks Junos OS on EX4650 devices, packets received on the management interface (em0) but not destined to the device, may be improperly forwarded to an egress interface, instead of being discarded. Such traffic being sent by a client may appear genuine, but is non-standard in nature and should be considered as potentially malicious. This issue affects: Juniper Networks Junos OS on EX4650 Series: All versions prior to 19.1R3-S8; 19.2 versions prior to 19.2R3-S5; 19.3 versions prior to 19.3R3-S5; 19.4 versions prior to 19.4R3-S7; 20.1 versions prior to 20.1R3-S3; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S2; 21.1 versions prior to 21.1R3-S1; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R2; 21.4 versions prior to 21.4R2; 22.1 versions prior to 22.1R1. Debido a una vulnerabilidad de Inicialización Inapropiada en Juniper Networks Junos OS en dispositivos EX4650, los paquetes recibidos en la interfaz de administración (em0), pero que no están destinados al dispositivo, pueden reenviarse incorrectamente a una interfaz de salida, en lugar de descartarse. Este tráfico enviado por un cliente puede parecer genuino, pero no es de naturaleza estándar y debe considerarse como potencialmente malicioso. • https://kb.juniper.net/JSA69494 • CWE-665: Improper Initialization •
