今天早上起来上网发现公司网站又被注入了，郁闷死了，赶快还原！！！
不过也多亏这注入，让我知道怎么简单的分析IIS日志了，呵呵，原来只要ctrl+f查找20%字符串就行，查到到如下东西
/forum/show.aspx titleid=318&caid=20%20And%20Cast(IS_SRVROLEMEMBER(0x730079007300610064006D0069006E00)%20as%20varchar(1))%2Bchar(124)=1 80 - 117.32.250.106 Mozilla/4.0 302 0 0
呵呵，原来show.aspx这个页面没有经过验证，赶快补上。。。
然后自己用.NET做了个检测数据库中的表中的字段中的内容有没有注入脚本的页面，看来以后每天都得要运行这个页面检测一次哦！！！

string sql_count =

// 判断该表该字段中是否含有script脚本
int count = int.Parse(myClass.myDataGet.getDataScalar(sql_count).ToString());
if (count > 0)
{
Response.Write(tbName + " 表中的 " + tbColName +
" 字段含有脚本！<br>SQL语句：<span style='color:blue;'>" + HttpUtility.HtmlEncode(sql_count) + "</span><br><br>");
}
}
}
}
}
}
把代码记录下来，以备后用！
