- →Trigger condition involves overriding Object.defineProperty with a getter that returns a function using rest parameters, then constructing Intl.NumberFormat — look for scripts that redefine Object.defineProperty via defineProperty itself (self-referential property trap) ↗
- →PoC abuses Intl.Collator property definition during Intl.NumberFormat initialization to trigger type confusion; monitor for scripts that reassign the global Intl object and simultaneously call Object.defineProperty on Intl internals ↗
- →The getter in the exploit returns a bit-shifted magic constant (0x1234567 >> 1) as a type-confused value; this value may appear in memory dumps or crash analysis of CVE-2016-7287 exploitation attempts ↗
- →Vulnerability class is Internationalization (Intl) initialization type confusion in Microsoft Edge scripting engine (MS16-144); alert on Edge/IE11 JScript engine crashes or memory corruption during Intl object construction ↗
- →Web-based attack vector: attacker hosts a crafted page exploiting IE/Edge scripting engine; consider inspecting HTTP responses served to IE11/Edge user-agents containing simultaneous use of Object.defineProperty redefinition and Intl.NumberFormat construction ↗
- →ActiveX-based delivery also possible: attacker embeds ActiveX control marked 'safe for initialization' in Office documents hosting IE rendering engine — monitor Office processes spawning IE rendering engine with scripting activity ↗
- ·Exploit publicly disclosed (PoC on Exploit-DB as exploit 40948) but Microsoft MSRC assessed exploitation status as 'Publicly Disclosed: No; Exploited: No' at time of patch — treat PoC as a detection reference, not confirmed in-the-wild activity ↗
- ·Affects both Microsoft Internet Explorer 11 and Microsoft Edge; detection logic must cover both browsers' scripting engine contexts ↗

CVE-2016-7287 [HIGH] Scripting Engine Memory Corruption Vulnerability
Scripting Engine Memory Corruption Vulnerability
Description: A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
In a web-based attack scenario, an attacker could host a specially crafted websi
