CVE-2017-8739: Microsoft Edge in Microsoft Windows 10 1703 allows an attacker to obtain information to further compromise...

Security readout for executives and security teams

CVE-2017-8739 is an information disclosure issue in Microsoft Edge on Windows 10 version 1703. The weakness is in how Edge's scripting engine handles objects in memory. It could expose information that helps an attacker further compromise a user's system, but the bundle provides no CVSS score or active exploitation evidence. Likely limited to systems running Microsoft Edge on Microsoft Windows 10 1703. Environments that retired that Windows release or no longer use legacy Edge are less likely to be exposed, but asset validation is required. Prioritize as a legacy endpoint hygiene issue unless asset discovery finds exposed Windows 10 1703 systems. The business urgency rises where unpatched legacy browsing is still allowed, because information disclosure can support chained compromise. Mitigation focus: Review the Microsoft MSRC advisory for official update and mitigation guidance.; Apply relevant Microsoft security updates where the affected platform is present.; Prioritize retirement or isolation of Windows 10 1703 systems..
