Security issue with PowerShell

martin — Thu, 25 Jan 2007 08:47:00 GMT

Hi guys,

after (too) long time I can finally return to Powershell (I spend few months creating batch framework to manage citrix servers, right now it is about 980 scripts).

I was playing with Get-Credential:

$Operator = get-credential

I provided my username/password. If I have a look at object, I can see Password property and GetPassword() method. I tried this, Output is in System.Security.SecureString.

I was just thinking how PowerShell is handling explicit authentication, so I had a look at available properties and methods - GetNetworkCredential grab my eye, so I tried it. And I was really surprised by output:

mzugec>$operator.GetNetworkCredential()

UserName                   Password                   Domain
--------                           --------                         ------
mzugec                       YouPwdInPlainText     MyDomain

Replace YouPwdInPlainText with your actual password! So be aware, if you are using get-credentials, it is very easy to retrieve your actual password!

How to create GUI in Monad?

Hey guys! Sometimes you need to create some GUI - msgbox, inputbox etc... Till now it was really problem if you needed something more advanced - for example checkboxes etc. With Monad it is quite easy! And thats because you can use .net... In fact it is similar to creating normal program!

[Reflection.Assembly]::LoadWithPartialName(”System.Windows.Forms”)

$Form = New-Object System.Windows.Forms.Form

$Button = New-Object System.Windows.Forms.Button

$Form.Text = “You didnt clicked yet”

$Button.Text = “Click here!”

$Button.Add_Click({$Form.Text = “You clicked!})

$Form.Controls.Add($Button)

$Form.ShowDialog()

Monad documentation

I noticed this information on Lee`s blog - Monad documentation from PDC is available!

And it is great, I noticed few things I didnt know you could do, for example

Filter get-company {$_.Company}

Get-Process | Get-Company

Download it today! :)

First alternative shell for Monad!

martin — Mon, 03 Oct 2005 17:20:00 GMT

Heh, I was waiting for this moment, however I didnt know it will happen before first release :)

We have alternative shell for monad - it is called jaMSH (Jeff`s Alternative Monad SHell)... It includes few nice features - greater autocomplete, emacs/vi editing etc...

However it was really unstable on my machine and really slow :( I will wait for next release...

Monad = use structures from System namespace

martin — Fri, 16 Sep 2005 14:58:00 GMT

Hey, did you know how to use structures from System namespace? Like DateTime for example?

It is quite easy - [structure]::StaticMethod.

For example to insert current date to variable $Today, you just need this line of code:

MSH> $Today = [DateTime]::Now()

MSH> $test = ([Guid]::NewGuid()).ToString()
MSH> $Test
