CVE-2023-44189
Estado: ModificadaMedia (5.4)—
An Origin Validation vulnerability in MAC address validation of Juniper Networks Junos OS Evolved on PTX10003 Series allows a network-adjacent attacker to bypass MAC address checking, allowing MAC addresses not intended to reach the adjacent LAN to be forwarded to the downstream network. Due to this issue, the router will start forwarding traffic if a valid route is present in forwarding-table, causing a loop and congestion in the downstream layer-2 domain connected to the device.
This issue affects Juniper Networks Junos OS Evolved on PTX10003 Series:

"value": "Una vulnerabilidad de validación de origen en la validación de direcciones MAC de Juniper Networks Junos OS Evolved en la serie PTX10003 permite que un atacante adyacente a la red omita la verificación de direcciones MAC, lo que permite que las direcciones MAC que no están destinadas a llegar a la LAN adyacente se reenvíen a la red descendente. Debido a este problema, el router comenzará a reenviar tráfico si hay una ruta válida en la tabla de reenvío, lo que provocará un bucle y una congestión en el dominio de capa 2 descendente conectado al dispositivo.
