Les permissions d’un share

Dans cet article, nous avions exploré les fonctions de Netapi32.dll pour récupérer des informations relatives aux shares SMB.

Nous allons maintenant voir comment récupérer les permissions de ces shares.

Il existe des fonctions qui gèrent les SIDs, ACLs, et ACEs dans advapi32.dll, et nous allons capitaliser sur l’article concernant le Netapi pour en faire un tout, et lire les permissions sans passer par WMI.

Tout d’abord voici une nouvelle version du script netapi.ps1:

<#  
.SYNOPSIS  
    Defines functions in Netapi32.dll and advapi32.dll so they can be used within 
    Powershell to retrieve SMB share information.
.DESCRIPTION  
    Supported functions:
		Get-Shares <server> <level>
			server can be $null to point to localhost
			level can be 0 1 2 502 503
			Remark: Uses NetShareEnum
		
		Get-NetStatistics <server> <type>
			type can be SERVER or WORKSTATION
			Remark: Uses NetStatisticsGet

		Get-Sessions <server> <level> <user> <client>
			level can be 0 1 2 10 502
			Remark: Uses NetConnectionEnum

		Get-OpenFiles <server> <level> <user> <path>
			level can be 2 3
			Remark: Uses NetFileEnum

.EXAMPLE
	Get-NetStatistics localhost SERVER
	Get-Shares localhost 503
	Get-Sessions localhost 502
	Get-OpenFiles localhost 3

.SYNOPSIS

Defines functions in Netapi32.dll and advapi32.dll so they can be used within

Powershell to retrieve SMB share information.

.DESCRIPTION

Supported functions:

Get-Shares <server> <level>

server can be $null to point to localhost

level can be 0 1 2 502 503

Remark: Uses NetShareEnum

Get-NetStatistics <server> <type>

type can be SERVER or WORKSTATION

Remark: Uses NetStatisticsGet

Get-Sessions <server> <level> <user> <client>

level can be 0 1 2 10 502

Remark: Uses NetConnectionEnum

Get-OpenFiles <server> <level> <user> <path>

level can be 2 3

Remark: Uses NetFileEnum

.EXAMPLE

Get-NetStatistics localhost SERVER

Get-Shares localhost 503

Get-Sessions localhost 502

Get-OpenFiles localhost 3

Il faudra avec cette version dot-sourcer le script pour que les cmdlets soient définies:

. $PSScriptRoot\netapi.ps1

1	. $PSScriptRoot\netapi.ps1

Une fois les cmdlets définies nous allons avoir besoin de celle qui récupère le level 502 des shares:

$shares = Get-Shares -level 502 -server localhost

1	$shares = Get-Shares -level 502 -server localhost

et avec cet array, nous allons pour chaque élément vérifier si le SecurityDescriptor est présent. Pour ensuite récupérer l’ACL dans un buffer en mémoire.

A partir de l’ACL nous pouvons récupérer l’ACE qui contient le SID et la permission.

Avec un peu de gymnastique de pointeurs et buffers de structures, nous allons pouvoir traduire tout cela en objets Powershell qui peuvent être utilisés.

Voici le script complet:

. $PSScriptRoot\netapi.ps1
$shares = Get-Shares -level 502 -server localhost

foreach ($share in $shares)
{
	$aclPresent = 0
	$acl = 0
	$aclDefaulted = 0
	
	if ($share.SecurityDescriptor -ne 0)
	{
		$ret = [Netapi]::GetSecurityDescriptorDacl($share.SecurityDescriptor,[ref]$aclPresent,[ref]$acl,[ref]$aclDefaulted)

		if ($aclPresent -eq $true)
		{		
			$aclInfo = New-Object netapi+ACL_SIZE_INFORMATION
			$length = [System.Runtime.Interopservices.Marshal]::SizeOf([System.Type]$aclInfo.GetType())
			$AclSizeInformation = 2 # Enum defined in ACL_INFORMATION_CLASS
			
			$ret = [Netapi]::GetAclInformation($acl,[ref]$aclInfo,$length,$AclSizeInformation)
		
			for($i = 0; $i -lt $aclInfo.AceCount; $i++)
			{
				$ptr = 0
				$aceStruct = New-Object netapi+ACCESS_ALLOWED_ACE
				$ret = [netapi]::GetAce($acl, $i, [ref]$ptr);
				$ace = [system.runtime.interopservices.marshal]::PtrToStructure($ptr, [System.Type]$aceStruct.GetType())
				
				if ($null -ne $ace)
				{
					$increment = [System.Runtime.Interopservices.Marshal]::OffsetOf([System.Type]$aceStruct.GetType(),"SidStart")
					$offset = $ptr.ToInt64()
			        $offset += $increment
					$sidSize = [Netapi]::GetLengthSid($offset)

					$bytes= $encryptedBytes = New-Object byte[] $sidSize

Voici un mise à jour du script d’exemple, cette nouvelle version traite le problème de l’exception « Some or all identity references could not be translated. ».

Pour régler ce problème nous allons récupérer la liste des utilisateurs locaux d’une machine donnée et comparer les SIDs sans passer par Translate.
