ChakraCore and Internet Explorer in Microsoft Windows 7 SP1, Windows Server 2008 and R2 SP1, Windows 8.1 and Windows RT 8.1, Windows Server 2012 and R2, and Microsoft Edge and Internet Explorer in Windows 10 Gold, 1511, 1607, 1703, 1709, Windows Server 2016 and Windows Server, version 1709 allows an attacker to gain the same user rights as the current user, due to how Microsoft browsers handle objects in memory, aka "Scripting Engine Memory Corruption Vulnerability". This CVE ID is unique from CVE-2017-11836, CVE-2017-11837, CVE-2017-11838, CVE-2017-11839, CVE-2017-11840, CVE-2017-11841, CVE-2017-11843, CVE-2017-11846, CVE-2017-11859, CVE-2017-11861, CVE-2017-11862, CVE-2017-11866, CVE-2017-11869, CVE-2017-11870, CVE-2017-11871, and CVE-2017-11873.

Security readout for executives and security teams

This is a Microsoft browser scripting-engine flaw from 2017. If triggered, an attacker could run with the same privileges as the signed-in user. Business impact depends heavily on whether older Windows builds, Internet Explorer, Microsoft Edge, or ChakraCore remain in use. Exposure is most likely on legacy Microsoft platforms listed in the CVE: Windows 7 SP1, Windows 8.1/RT 8.1, Server 2008/2012/2016 variants, and Windows 10 Gold through 1709 using affected browser components. Treat this as a legacy exposure cleanup priority. It is not KEV-listed in the supplied bundle, but the impact is serious where affected Microsoft browser components remain present, especially under privileged user accounts. Mitigation focus: Review the Microsoft MSRC advisory for applicable vendor security updates or guidance.; Inventory systems running the affected Windows, Internet Explorer, Edge, or ChakraCore versions.; Prioritize remediation for internet-facing, shared, or high-privilege user workstations..
