Descriptions

On Verizon 5G Home LVSKIHP InDoorUnit (IDU) 3.4.66.162 and OutDoorUnit (ODU) 3.33.101.0 devices, the CRTC and ODU RPC endpoints rely on a static account username/password for access control. This password can be generated via a binary included in the firmware, after ascertaining the MAC address of the IDU's base Ethernet interface, and adding the string DEVICE_MANUFACTURER='Wistron_NeWeb_Corp.' to /etc/device_info to replicate the host environment. This occurs in /etc/init.d/wnc_factoryssidkeypwd (IDU).

En los dispositivos Verizon 5G Home LVSKIHP InDoorUnit (IDU) versión 3.4.66.162 y OutDoorUnit (ODU) versión 3.33.101.0, los endpoints RPC de CRTC y ODU dependen de un nombre de usuario/contraseña de cuenta estática para el control de acceso. Esta contraseña puede generarse por medio de un binario incluido en el firmware, después de averiguar la dirección MAC de la interfaz Ethernet base de la IDU, y añadir la cadena DEVICE_MANUFACTURER="Wistron_NeWeb_Corp." a /etc/device_info para replicar el entorno del host. Esto ocurre en /etc/init.d/wnc_factoryssidkeypwd (IDU)
