CVE-2017-11927

MEDIUM 6.5EPSS 9.62%

Does this matter?

Lower severity and a low EPSS score (9.62%). Track it; it rarely justifies an emergency change on its own.

Description

Windows 7 SP1, Windows 8.1 and RT 8.1, Windows Server 2008 SP2 and R2 SP1, Windows Server 2012 and R2, Windows 10 Gold, 1511, 1607, 1703 and 1709, Windows Server 2016 and Windows Server, version 1709 allow an information vulnerability due to the way the Windows its:// protocol handler determines the zone of a request, aka "Microsoft Windows Information Disclosure Vulnerability".
