Detection & IOCsextracted from sources · hover to see the quote
- →Crash occurs in edgehtml!COptionsCollectionCacheItem::GetAt+0x51 at instruction 'mov rax,qword ptr [rax+rdx*8]' — monitor for access violations in MicrosoftEdgeCP.exe at this offset as an indicator of exploitation attempts. ↗
- →The call stack shows the vulnerability is triggered through chakra!Js::CrossSite::MarshalVar — an access violation with rax pointing to an invalid/out-of-bounds address (e.g., rax=00000001afccb7d4 with rcx=ffff000000000000) is a strong crash indicator. ↗
- →Enable Page Heap on MicrosoftEdgeCP.exe and disable MemGC to reliably reproduce and detect the out-of-bounds read crash in edgehtml!COptionsCollectionCacheItem::GetAt. ↗
- ·The first debug log (without Page Heap / MemGC disabled) crashes in chakra!Js::CrossSite::MarshalVar rather than directly in COptionsCollectionCacheItem::GetAt, meaning the crash location varies by heap configuration — detection rules should account for both call stacks. ↗
- ·Exploit status from MSRC indicates 'Publicly Disclosed: No; Exploited: No; Latest Software Release: Exploitation More Likely' — the PoC is public on Exploit-DB but no in-the-wild exploitation was confirmed at time of advisory. ↗

CVE-2017-8734 [HIGH] Microsoft Edge Memory Corruption Vulnerability
Microsoft Edge Memory Corruption Vulnerability
Description: A remote code execution vulnerability exists when Microsoft Edge improperly accesses objects in memory. The vulnerability could corrupt memory in such a way that enables an attacker to 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 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.
An attacker could host a specially crafted website that is designed to exploit the vulnerability through Microsoft Edge, and then convince a user to
