The instance rescue mode in OpenStack Compute (Nova) 2013.2 before 2013.2.3 and Icehouse before 2014.1, when using libvirt to spawn images and use_cow_images is set to false, allows remote authenticated users to read certain compute host files by overwriting an instance disk with a crafted image.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
