An information disclosure vulnerability exists when Windows Hyper-V writes uninitialized memory to disk. An attacker could exploit the vulnerability by reading a file to recover kernel memory. To exploit the vulnerability, an attacker would first require access to a Hyper-V host. The security update addresses the vulnerability by ensuring Hyper-V properly initializes memory before writing it to disk.
With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
