Successful exploitation results in code execution in the context of the ScadaLTS server process (root), leading to full compromise of the underlying system."

La explotación exitosa resulta en la ejecución de código en el contexto del proceso del servidor ScadaLTS (root), lo que lleva a un compromiso total del sistema suporacente."
