Alena Prokharchyk commented on CLOUDSTACK-1327:
-----------------------------------------------
The max template size that can be downloaded by the regular user, is limited
via "max.template.iso.size" global config parameter ("The maximum size for a
downloaded template or ISO (in GB)"). Default value is 50GB.
> Cloudstack allows users to import huge templates from unauthorised URLs

> Key: CLOUDSTACK-1327
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1327
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Management Server, Template
> Affects Versions: 4.0.1
> Environment: Centos 6 x86_64 kvm hypervisors
> Reporter: Nux
> Priority: Critical
>
> Because Cloudstack deploys instances as r/w snapshots of the template,
> importing a template with, say 1 TB diskspace will give you 1 TB instances...
> this will lead to service abuse.
> Currently Cloudstack allows regular users to install templates from not
> allowed URLs.
