vb.net - 以管理员身份运行带有提升标志的命令（使用已知密码）

Question

我有一个需要由标准用户运行的 VB.net 应用程序，但有某些功能需要以本地管理员身份运行，并带有提升的标志（或 LSA、受信任的安装程序或其他我关心的系统帐户）。这是一个帮助程序，允许用户在不输入本地管理员凭据和通过 UAC 提示符的情况下运行内部应用程序。UAC 旨在防止程序自发获得管理员权限，但在我的情况下，我们打算将这些凭据嵌入程序中。我们不想禁用 UAC，只是绕过它已经以其他方式完成，我们只需要使用 run as admin 标志启动运行命令（例如 reg add 或 CMD）。简单地做一个 runas 是行不通的，因为这些是标准用户帐户，

澄清一下，基本程序永远不会以管理员身份运行。目的是使用它来调用另一个程序或带有嵌入式凭据的 cmd.exe。标准用户将使用它。

我已经尝试过 VB.Netsystem.diagnostics.process.start.flag = "runas"属性，但没有奏效。

我也尝试了下面的代码，但这也不起作用并返回“1”。与

RunProgram("Administrator", "password", Environment.MachineName, "cmd.exe", "/c reg add HKLM\Software\Microsoft\Windows\CurrentVersion\Run /f /v MyProgram /D " & System.Windows.Forms.Application.ExecutablePath())

任何想法如何进行？

我还尝试了一个使用 VB.Net 的简单 cmd runas

system.diagnostics.process.start.flag = "runas", and now Lib "Advapi32" Alias "CreateProcessWithLogonW".

下面是模块代码：

Public Module Impersonation

#Region "API Structures"

        Dim hProcess As System.IntPtr

    End Structure

    Public Declare Unicode Function CreateProcessWithLogon Lib "Advapi32" Alias "CreateProcessWithLogonW" _

    Private Declare Function CloseHandle Lib "kernel32" (ByVal hObject As System.IntPtr) As Integer

#End Region



    Public Function RunProgramold(ByVal UserName As String, ByVal Password As String, ByVal Domain As String, ByVal Application As String, ByVal CommandLine As String)

        Dim siStartup As STARTUPINFO
        Dim piProcess As PROCESS_INFORMATION
        Dim intReturn As Integer

        If CommandLine Is Nothing OrElse CommandLine = "" Then CommandLine = String.Empty

        siStartup.cb = Marshal.SizeOf(siStartup)
        siStartup.dwFlags = 0

        intReturn = CreateProcessWithLogon(UserName, Domain, Password, LOGON_WITH_PROFILE, Application, CommandLine, NORMAL_PRIORITY_CLASS Or CREATE_DEFAULT_ERROR_MODE Or CREATE_NEW_CONSOLE Or CREATE_NEW_PROCESS_GROUP, IntPtr.Zero, IntPtr.Zero, siStartup, piProcess)

        If intReturn = 0 Then
            Dim errorMessage As New Win32Exception(Marshal.GetLastWin32Error())
            MsgBox("Cant start program:" & Application & CommandLine & errorMessage.Message)
            Throw New System.ComponentModel.Win32Exception(Marshal.GetLastWin32Error())
        End If

        CloseHandle(piProcess.hProcess)
        CloseHandle(piProcess.hThread)

        Return intReturn
    End Function
End Module

它应该以管理员身份运行 Reg Add 并将新条目写入注册表中的运行文件夹。没有消息产生，我得到的唯一错误是“1”。
