Título: Codigo JS en router ClearAcess, vulnerable?
Publicado por: CloudswX en 7 Septiembre 2011, 05:26 am
Pues wenas gente.. Sucede que me han instalado un router wireless marca ClearAcces y para entrar a su configuracion (obvio despues de estar conectado) es necesario digitar usuario y pass los cuales son el numero serial que viene en la caja del router. Mi pregunta es la siguiente, es posible vulnerar el sistema del login (que esta hecho en JS) aprovechando alguna brecha en el codigo. Se muy poco o casi nada de JS (solo lo suficiente para superar el reto de zona cero, jejej) por eso pegare aqui el codigo para que todos les hechen un ojo y me digan si hallan algun hueco por donde vulnerar. /*
