> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: API
> Affects Versions: 4.6.0, 4.7.0
> Reporter: Wido den Hollander
>
> Currently the userdata passed to "deployvirtualmachine" is not verified if it
> is valid base64.
> It is passed all the way down the the VR without validating if it is correct
> base64.
> We simple check if it is valid should be done in the management server before
> attempting a deployment.
