查找数据库中的某表某字段中是否有注入脚本
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!!!
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!!!
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!!!
