如何使用/不使用PowerShell的提升特权来运行exe [英] How to run exe with/without elevated privileges from PowerShell

问题描述

我想以一种简单的方法来运行来自同一用户的具有不同特权的进程，而无需询问或知道他/她的密码。如有必要，可以进行对话。我宁愿不启动PowerShell子过程来完成此任务。

方案1：
PowerShell脚本在admin中运行-模式。我想在同一用户上启动没有管理员特权的脚本或.exe。

方案2：
PowerShell脚本在正常模式下运行。我想在同一用户上启动具有管理员权限的脚本或.exe。

解决方案

让我们将其分为三部分。

首先确定当前会话是否正在使用管理员权限运行：

  $ CurrentID = [System.Security.Principal.WindowsIdentity] :: GetCurrent（）
 $ CurrentPrincipal =新对象System.Security.Principal.WindowsPrincipal（$ CurrentID）
 $ adminRole = [System.Security。 Principal.WindowsBuiltInRole] :: Administrator 
 
＃检查会话当前是否具有管理员权限
 
 if（$ CurrentPrincipal.IsInRole（$ adminRole））{
写主机是的，我们正在提升。 
}其他{
写主机不，这是正常的用户会话。 
} 
  

现在，如果我们运行时有无海拔，则可以开始新的具有以下特权的进程：

  $ newProc =新对象System.Diagnostics.ProcessStartInfo PowerShell 
＃指定要运行的内容
 $ newProc.Arguments = powershell.exe 
＃如果设置了此选项，进程将被提升
 $ newProc.Verb = runas 
 [系统.Diagnostics.Process] :: Start（$ newProc）
  

最后，如果我们拥有更高的特权，但是想在没有...的情况下开始新的流程。

我不知道。将不得不尝试找到答案，但是由于这不是一个常见的情况，所以到目前为止我还没有运气。

编辑：我现在看到了针对这种情况的几个解决方案。 .NET / PowerShell中没有本地方法可以做到这一点。有些非常复杂（调用一些12个COM对象）。此

I would like an easy way to run a process with different privileges from the same user without asking or knowing his/her password. A dialog is okay if necessary. I would prefer not to launch a PowerShell sub-process to accomplish this.

Scenario 1: PowerShell script is running in admin-mode. I want to launch a script or an .exe without admin privileges but on the same user.

Scenario 2: PowerShell script is running in normal mode. I want to launch a script or an .exe with admin privileges on the same user.

解决方案

Let's split this into three parts.

First determine if current session is running with admin privileges:

$CurrentID = [System.Security.Principal.WindowsIdentity]::GetCurrent()
$CurrentPrincipal = new-object System.Security.Principal.WindowsPrincipal($CurrentID)
$adminRole = [System.Security.Principal.WindowsBuiltInRole]::Administrator

# Check to see if session is currently with admin privileges

if ($CurrentPrincipal.IsInRole($adminRole)) {
    write-host "Yes we are running elevated."
}else{
    write-host "No this is a normal user session."
}

Now, if we are running with or without elevation, you can start a new process with elevated privileges like this:

$newProc = new-object System.Diagnostics.ProcessStartInfo "PowerShell"
# Specify what to run
$newProc.Arguments = "powershell.exe"
# If you set this, process will be elevated
$newProc.Verb = "runas"
[System.Diagnostics.Process]::Start($newProc)

And lastly, if we have elevated privileges, but would like to start a new process without...

I have no idea. Will have to try to find the answer to this, but as it is not a common scenario, I had no luck so far.

EDIT: I have now seen a couple of "solutions" for this scenario. There is no native way to do this in .NET/PowerShell. Some are quite complicated (Calls to some 12 COM objects). This vista-7-uac-how-to-lower-process-privileges is a good reference.

The one that seems most elegant to me, is exploiting a "bug" in explorer.exe. Just launch you .exe using explorer.exe and the resulting process runs without privilege elevation again.

$newProc = new-object System.Diagnostics.ProcessStartInfo "PowerShell"
# Specify what to run, you need the full path after explorer.exe
$newProc.Arguments = "explorer.exe C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe"
[System.Diagnostics.Process]::Start($newProc)

EDIT #2: Another way I have just found to start a new non-elevated process from an already elevated environment is to use the runas.exe with the 0x20000 (Basic User) trust level:

C:\> runas /showtrustlevels The following trust levels are available on your system: 0x20000 (Basic User) C:\> runas /trustlevel:0x20000 devenv
