HUST-WIRELESS自动登录/登出脚本

fffonion

11 年前

这里有编译好的win32程序http://t.cn/zQAJ6do

研究了下HUST WIRELESS的网页登录；抓了几个包看了下，后台是锐捷的SAM无误，界面的js竟然用的是中国移动的-。-

工作方式很诡异：

访问任意网址时AP返回一个页面，用js跳转到index.jsp；通过GET方式提交了一堆参数，大概是SHA1过的，大概还是加了盐的，反正没试出来；嘛，╮(╯-╰)╭

这个index.jsp再重定向到./eportal/userV2.do?method=login，并且将GET方式传递给index.jsp的参数都以隐藏表单元素的方式藏在了返回的网页里：

<form name="userV2Form" method="post" action="/eportal/userV2.do?method=login" onsubmit="return checkForm();" id="loginForm">
		<input type="hidden" name="wlanuserip" value="1a6ff81049ec892dd2d9e3a55609efe2" id="wlanuserip">
		<input type="hidden" name="wlanacname" value="18260f9e92a595cf3d778ed7f6ead8a8" id="wlanacname">
		<input type="hidden" name="nasip" value="8df3b80e79b397a516656c1e9cf9cb08" id="nasip">
		<input type="hidden" name="url" value="http://www.baidu.com/" id="url">
		<input type="hidden" name="ssid" value="37ac66ecf843a939bdf3991faaee1a4c" id="ssid">
		<input type="hidden" name="mac" value="e8349ecfc6e6b9de758d2ff9054f6449" id="mac">
		<input type="hidden" name="t" value="wireless-v2" id="t">

submit时将隐藏表单元素和用户输入的用户名密码都POST到/eportal/userV2.do?method=login，都特么是明文的0.0，你特么把ip啊mac啊都加密了，用户名密码都特么是明文的搞毛啊(*￣▽￣*)
若登陆成功则返回一个成功结果页，包含一个重定向（貌似用的也是中国移动的），告诉你上线成功

下线是GET方式，提交到./eportal/userV2.do?method=logout，网页提交的只有三个参数（nasip, mac, ），反正我是把上一步隐藏的input里的所有的参数都提交了，好像没出问题- -正常下线了。

finally，python脚本，方便命令行操作，可以加-s保存密码，-c清除保存的密码

窝的python依然写得非常丑，请笑纳www；之所以用httplib2而不是urllib2是因为那个用得不顺手而且不能gzip → →这里用urllib2的版本http://t.cn/zQAJ6do
