Mysql提權(quán)方法利用
更新時間：2007年06月06日 00:00:00 作者：
mysql是一個常用的數(shù)據(jù)庫系統(tǒng),應(yīng)用極廣泛,如果得到一個mysql的用戶權(quán)限,如果提升呢,下面這個思路很先進! 但得有一定編程基礎(chǔ)!
現(xiàn)在網(wǎng)上通過mysql獲得系統(tǒng)權(quán)限大都通過MYSQL的用戶函數(shù)接口UDF，比如Mix.dll和my_udf.dll。在Mix.dll中有一個MixConnect函數(shù)它會反彈shell，但是使用這個函數(shù)會造成MYSQL假死，前些天我就用這個函數(shù)反彈shell后由于網(wǎng)絡(luò)原因不一會兒就斷開了，造成了MYSQL當?shù)?。my_udf.dll和Mix.dll相似，但它是通過my_udfdoor函數(shù)在服務(wù)器上偵聽3306端口，用nc正向連接獲得shell，但它的功能顯的少了點，于是我決定自己寫一個功能強大，運行穩(wěn)定的UDF。
MYSQL有一個開發(fā)包，它定義了自己的接口，變量類型，以及函數(shù)執(zhí)行順序。比如我們要寫一個open3389函數(shù)，我們可以這樣寫：
程序代碼
extern "C" __declspec(dllexport)my_bool open3389_init(UDF_INIT *initid, UDF_ARGS *args, char *message)
{
//在open3389函數(shù)之前調(diào)用，一般用于初始化工作，為可選函數(shù)；
//return 1出錯 ,0 正常
return 0;
}
extern "C" __declspec(dllexport)char *open3389(UDF_INIT *initid, UDF_ARGS *args,char *result, unsigned long *length,char *is_null, char *error)
{
//真正實現(xiàn)功能的函數(shù)，必需函數(shù)；
/*
函數(shù)內(nèi)容;
return 結(jié)果;
*/
}
extern "C" __declspec(dllexport)void open3389_deinit(UDF_INIT *initid)
{
//在open3389函數(shù)之后調(diào)用，一般用于內(nèi)存釋放，可選函數(shù)；
}
以上的open3389函數(shù)的返回值是char *類型的，如果是其它類型函數(shù)的參數(shù)列表也會有所不同，具體的可見MYSQL參考手冊。
在寫MYSQL UDF時另一個必須考慮的問題是程序的穩(wěn)定時，它要經(jīng)的起各種變態(tài)輸入的考驗，否則一旦程序出錯MYSQL服務(wù)進程就會當?shù)簟?nbsp;
以下是我寫的UDF內(nèi)容，它包含10個函數(shù)：
cmdshell 執(zhí)行cmd；
downloader 下載者,到網(wǎng)上下載指定文件并保存到指定目錄；
open3389 通用開3389終端服務(wù)，可指定端口(不改端口無需重啟)；
backshell 反彈Shell；
ProcessView 枚舉系統(tǒng)進程；
KillProcess 終止指定進程；
regread 讀注冊表；
regwrite 寫注冊表；
shut 關(guān)機，注銷，重啟；
about 說明與幫助函數(shù)；
使用方法:
創(chuàng)建函數(shù)：create function 函數(shù)名(區(qū)分大小寫) returns string soname 'dll名' (注意路徑)；
刪除函數(shù)：delete function 函數(shù)名；
使用函數(shù)：select 函數(shù)名(參數(shù)列表)；獲取參數(shù)信息可使用select 函數(shù)名("help")；
以上幾個函數(shù)都經(jīng)過多次的測試（測試平臺：MYSQL 5.0.24-community-nt、Windows XP），不太可能會造成MYSQL假死等現(xiàn)象，但也不排除在特殊環(huán)境，特殊輸入的情況下出錯的可能，如發(fā)現(xiàn)bug可通知我，QQ：185826531（langouster）

現(xiàn)在網(wǎng)上通過mysql獲得系統(tǒng)權(quán)限大都通過MYSQL的用戶函數(shù)接口UDF，比如Mix.dll和my_udf.dll。在Mix.dll中有一個MixConnect函數(shù)它會反彈shell，但是使用這個函數(shù)會造成MYSQL假死，前些天我就用這個函數(shù)反彈shell后由于網(wǎng)絡(luò)原因不一會兒就斷開了，造成了MYSQL當?shù)?。my_udf.dll和Mix.dll相似，但它是通過my_udfdoor函數(shù)在服務(wù)器上偵聽3306端口，用nc正向連接獲得shell，但它的功能顯的少了點，于是我決定自己寫一個功能強大，運行穩(wěn)定的UDF。
MYSQL有一個開發(fā)包，它定義了自己的接口，變量類型，以及函數(shù)執(zhí)行順序。比如我們要寫一個open3389函數(shù)，我們可以這樣寫：
程序代碼
extern "C" __declspec(dllexport)my_bool open3389_init(UDF_INIT *initid, UDF_ARGS *args, char *message)
{
//在open3389函數(shù)之前調(diào)用，一般用于初始化工作，為可選函數(shù)；
//return 1出錯 ,0 正常
return 0;
}
extern "C" __declspec(dllexport)char *open3389(UDF_INIT *initid, UDF_ARGS *args,char *result, unsigned long *length,char *is_null, char *error)
{
//真正實現(xiàn)功能的函數(shù)，必需函數(shù)；
/*
函數(shù)內(nèi)容;
return 結(jié)果;
*/
}
extern "C" __declspec(dllexport)void open3389_deinit(UDF_INIT *initid)
{
//在open3389函數(shù)之后調(diào)用，一般用于內(nèi)存釋放，可選函數(shù)；
}
以上的open3389函數(shù)的返回值是char *類型的，如果是其它類型函數(shù)的參數(shù)列表也會有所不同，具體的可見MYSQL參考手冊。
在寫MYSQL UDF時另一個必須考慮的問題是程序的穩(wěn)定時，它要經(jīng)的起各種變態(tài)輸入的考驗，否則一旦程序出錯MYSQL服務(wù)進程就會當?shù)簟?nbsp;
以下是我寫的UDF內(nèi)容，它包含10個函數(shù)：
cmdshell 執(zhí)行cmd；
downloader 下載者,到網(wǎng)上下載指定文件并保存到指定目錄；
open3389 通用開3389終端服務(wù)，可指定端口(不改端口無需重啟)；
backshell 反彈Shell；
ProcessView 枚舉系統(tǒng)進程；
KillProcess 終止指定進程；
regread 讀注冊表；
regwrite 寫注冊表；
shut 關(guān)機，注銷，重啟；
about 說明與幫助函數(shù)；
使用方法:
創(chuàng)建函數(shù)：create function 函數(shù)名(區(qū)分大小寫) returns string soname 'dll名' (注意路徑)；
刪除函數(shù)：delete function 函數(shù)名；
使用函數(shù)：select 函數(shù)名(參數(shù)列表)；獲取參數(shù)信息可使用select 函數(shù)名("help")；
以上幾個函數(shù)都經(jīng)過多次的測試（測試平臺：MYSQL 5.0.24-community-nt、Windows XP），不太可能會造成MYSQL假死等現(xiàn)象，但也不排除在特殊環(huán)境，特殊輸入的情況下出錯的可能，如發(fā)現(xiàn)bug可通知我，QQ：185826531（langouster）
