CVE-2017-8661

CVE-2017-8661 is a memory corruption vulnerability in Microsoft Edge affecting Windows 10 versions 1607, 1703, and Windows Server 2016. This flaw allows an attacker to execute arbitrary code in the context of the current user by manipulating how Microsoft scripting engines handle objects in memory. With a CVSS score of 7.5 (High), exploitation requires user interaction (UI:R) and has high impact on confidentiality, integrity, and availability (C:H/I:H/A:H), though it has high attack complexity (AC:H). There is no evidence of active exploitation, nor are there publicly available exploit modules in Metasploit or ExploitDB, and community discussion is minimal.
