      "value": "A vulnerability in FiberHome GPON ONU HG6145F1 RP4423 allows the device's factory default Wi-Fi password (WPA/WPA2 pre-shared key) to be predicted from the SSID. The device generates default passwords using a deterministic algorithm that derives the router passphrase from the SSID, enabling an attacker who can observe the SSID to predict the default password without authentication or user interaction."

El dispositivo genera contraseñas predeterminadas utilizando un algoritmo determinista que deriva la frase de contraseña del router del SSID, lo que permite a un atacante que puede observar el SSID predecir la contraseña predeterminada sin autenticación ni interacción del usuario."
