 |
|
I'm trying to make a function to change the token privileges of a process so that you can use PROCESS_ALL_ACCESS, but I have a problem. In the OpenProcessToken API it asks for a handle to the process, but the only way I can think of being able to get that is to call OpenProcess with any access (but PROCESS_ALL_ACCESS) and then pass the handle, then after the function close the handle and open it up again, but this time with PROCESS_ALL_ACCESS. But that doesn't seem, right, is there any other way to do it? Here's my code:
| Code: |
BOOL SetPrivilege(LPCSTR lpPrivilege) {
HANDLE hToken;
TOKEN_PRIVILEGES tp;
LUID luid;
if(OpenProcessToken(, TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken)) { //I left the first param blank because that's the one I'm having trouble with
if(LookupPrivilegeValue(NULL, lpPrivilege, &luid)) {
tp.PrivilegeCount = 1;
tp.Privileges[0].Luid = luid;
tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
if(AdjustTokenPrivileges(hToken, FALSE, &tp, sizeof(TOKEN_PRIVILEGES), NULL, NULL)) {
return TRUE;
}
return FALSE;
}
return FALSE;
}
return FALSE;
}

| The first parameter is the process to set the privileges, call it with the first parameter being -1. (current process)

That requires me to inject a DLL into a process and call this function and pass GetCurrentProcess(). I want to be able to do this just from a normal application.

You want to change the current process privileges, so you can call OpenProcess with PROCESS_ALL_ACCESS from the current process, if you want to change another process's privileges, get the handle by calling OpenProcess, but if you get access denied then you still have to set the current process's privileges...

Oh, right. I just realized that you have to change the current process's privileges so that it can do whatever.
