CVE-2017-8585
Microsoft .NET Framework 4.6, 4.6.1, 4.6.2, and 4.7 allow an attacker to send specially crafted requests to a .NET web application, resulting in denial of service, aka .NET Denial of Service Vulnerability.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (9.50%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
