Fortunately, the current attack payloads from muhstik, mirai, hajime, and satori, have been tested to be broken and will not implant malicious code.
Soluciones o contramedidas
Para corregir esta vulnerabilidad y dado que la mayoría de estos dispositivos son bastantes antiguos, como comenta DZS, es necesario contactar con nuestro operador para que, o bien sustituya el modelo, o lo pueda actualizar remotamente.
The DZS ZNID-GPON-25xx and certain H640-series ONTs, including the software that introduced this vulnerability, were developed by an OEM supplier and resold by DZS. While designed and released more than 9 years ago, most of these products are now well past their sustainable service life. Because software support contracts are no longer offered for most of these products, we do not have direct insight to the total number of units that are still actively used in the field.
