Detection & IOCsextracted from sources · hover to see the quote
- →Trigger pattern: JavaScript array with float elements where a sparse segment is created via fractional index increments (i += 0.5) followed by large-index assignments, exploiting AppendLeftOverItemsFromEndSegment out-of-bounds read in Chakra/Edge ↗
- →Vulnerable function is AppendLeftOverItemsFromEndSegment in JavascriptArray.inl (Chakra engine); look for out-of-bounds read triggered by ScanForMissingValues operating on a non-head grown segment ↗
- →Exploit loops the trigger function 100 times to reliably reproduce the OOB read condition; repeated invocation pattern (100 iterations) may be observable in script profiling or JIT telemetry ↗
- →CVE-2018-0767 affects Microsoft Edge on Windows 10 1709 specifically; scope detection to that OS/browser version combination ↗
- ·Exploit status is publicly disclosed but assessed as Exploitation Unlikely for both latest and older software releases at time of advisory ↗
- ·The NVD source (DOC 1) describes CVE-2018-0800, a distinct but related scripting engine information disclosure CVE; do not conflate IOCs or descriptions between CVE-2018-0767, CVE-2018-0780, and CVE-2018-0800 ↗

CVE-2018-0767 [MEDIUM] 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
