简要描述：

很简单啊，把我市铁通的路由器+交换机扫了一个遍，能成功的登陆上了，好像还有一个是bgp的路由器。

详细说明：

放假时候在家无聊，想想测一下我家的铁通怎么样。于是百度了一下pppoe接口的ip，没想到竟然百度到了这个

这个就是我市铁通某一个骨干路由器的配置文档。。。真是猪一样的队友。虽然这份配置文件上，什么用户名密码啥的变了，但是给了好多接口IP的网段。可以方便NMAP去扫描IP网段。而且最重要的是，他的SNMP密码没有改变，好像是全内蒙的铁通都是这个SNMP密码。。。但是通辽那边的SNMP好像做ACL限制了，外人不能随便访问。可是赤峰铁通的这个就没有做限制，可以随便访问。下载一个SNMPWALK的小工具，就可以读取路由器的各种信息了。
首先，把他所有的接口的IP读出来，用NMAP扫描一下。
只要是开放telnet 23端口的，八成都是路由器。看型号，基本上都是华为的路由器。而华为路由器之前有一个漏洞，可以通过SNMP来获取到用户名密码。根据提示，获取到了几个路由器的密码，成功登陆上去。
路由器这种基础网络设备一般没人敢随便升级去，好好的不出问题升级他干嘛啊。所以呢，当有了安全漏洞，也没有及时去修复。现在的互联网安全这么重要，你还敢吧BGP的路由器也这么干。虽然这个BGP是IBGP，但是那也挺重要的呀。而且你们做好了工程呢，不要随便吧配置文件传网上，虽然你说什么密码是都加密了。可是你知道吗，华为，华三，HP的路由器，有了那种加密的密码，是可以还原密码的。不信你去GITHUB上去搜一下就有。就算你都改了，但是你SNMP密码没改啊，间接的把内蒙铁通的路由器SNMP密码暴露了。我也就看了一下赤峰的，估计其他地方的，这个问题更加严重。。。。
不过呢，也应该感谢你们，毕竟让我学到了好多运营商架构的网络

漏洞证明：

这个是四道湾镇的路由器配置
