我有一个脚本,用于根据转换为字符串的ACL输出创建自定义WMI类的实例。这最终是通过该WMI类查询权限。
这个过程的主要内容是:
ShellExecute()
返回以下错误:
ShellExecuteA(NULL, "edit", path.c_str(), NULL, NULL, SW_SHOWNORMAL);
我将Security.AccessControl.FileSystemAccessRule转换为字符串的方式似乎存在问题,因为使用下面的代码并提供文字字符串会创建一个没有问题的实例,并带有适当的值:
[cmdletbinding()]
param([Parameter(ValueFromPipeline=$True,
ValueFromPipelineByPropertyName=$True)]$Computer = '.')
$shares = gwmi -Class win32_share -ComputerName $computer | select -ExpandProperty Name
foreach ($share in $shares) {
$acl = $null
#Write-Host $share -ForegroundColor Green
#Write-Host $('-' * $share.Length) -ForegroundColor Green
$objShareSec = Get-WMIObject -Class Win32_LogicalShareSecuritySetting -Filter "name='$Share'" -ComputerName $computer
try {
$SD = $objShareSec.GetSecurityDescriptor().Descriptor
foreach($ace in $SD.DACL){
$UserName = $ace.Trustee.Name
If ($ace.Trustee.Domain -ne $Null) {$UserName = "$($ace.Trustee.Domain)\$UserName"}
If ($ace.Trustee.Name -eq $Null) {$UserName = $ace.Trustee.SIDString }
[Array]$ACL += New-Object Security.AccessControl.FileSystemAccessRule($UserName, $ace.AccessMask, $ace.AceType)
for( $i = 1; $i -lt $ACL.Length; $i++)
{
$permission = $ACL[$i] | Out-String
Write-Host "permission for $share is $permission"
Set-WmiInstance -Class TestShare -Puttype CreateOnly -Argument @{Name = $share; Permissions = $permission}
}
} #end foreach ACE
} # end try
catch
{
Write-host "Failed to create or update instance for share $share"
Write-Host ""
}
#$ACL
# Write-Host $('=' * 50)
} # end foreach $share
我已经查看了与返回的错误相关的technet论坛帖子,但问题似乎总是在尝试创建一个未创建的类的实例。这个班肯定在那里。有没有办法转换Security.AccessControl.FileSystemAccessRule而不会遇到这种情况,或者以不同的方式将该信息存储在自定义WMI类的实例中?
编辑:$ permission的示例输出,转换为字符串

答案 0 :(得分:0)
要创建对象,您可以通过以管理员身份运行以下代码段来执行此操作:
$WMI_Class = ""
$WMI_Class = New-Object System.Management.ManagementClass("Root\cimv2", $null, $null)
$WMI_Class.name = 'TestShare'
$WMI_Class.Properties.Add("Name", [System.Management.CimType]::String, $false)
$WMI_Class.Properties["Name"].Qualifiers.Add("key", $true)
$WMI_Class.Properties.Add("Permissions", [System.Management.CimType]::String, $false)
$WMI_Class.Put()
您可以通过创建虚拟对象来测试它(也应该以管理员身份运行):
Set-WmiInstance -Class TestShare -Puttype CreateOnly -Argument @{Name = 'test';Permissions = 'x'}
然后你的代码应该可以正常使用set-wmiinstance的这个小改动:
Set-WmiInstance -Class TestShare -Puttype CreateOnly -Argument @{Name = $share;Permissions = $permission.Replace("`r`n","`n")}
但是,我已将共享名称定义为键,并且属性没有写限定符。因此,您将无法稍后为同一共享修改该对象
