Detection & IOCsextracted from sources · hover to see the quote
- →The vulnerability is triggered via a type confusion in EntrySimpleObjectSlotGetter when accessing w.event on a cross-site window object while a Proxy's getPrototypeOf handler mutates the type of a float array (e.g., arr[0] = {}). Look for JIT-compiled code paths that call EntrySimpleObjectSlotGetter without a subsequent ImplicitCallFlags check. ↗
- →Exploit PoC requires an iframe to obtain a cross-site contentWindow object. Detection should look for JavaScript that creates an iframe, accesses contentWindow, wraps an array in a Proxy with a getPrototypeOf trap, and then calls a JIT-warmed function that reads a property from the cross-frame window object. ↗
- ·The exploit is publicly disclosed (PoC on Exploit-DB) but Microsoft's advisory states it had NOT been exploited in the wild at time of patch release. Exploitation likelihood was rated 'More Likely' for the latest software release. ↗
- ·The vulnerability only affects Microsoft Edge (HTML-based) and ChakraCore. The fix was shipped in ChakraCore v1.8.4 and Windows cumulative updates KB4103721, KB4103731, KB4103727, KB4103716, KB4103723. ↗

Chakra Scripting Engine Memory Corruption Vulnerability
Description: A remote code execution vulnerability exists in the way that the Chakra scripting engine handles objects in memory in Microsoft Edge (HTML-based). 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
