Detection & IOCsextracted from sources · hover to see the quote
- →Exploit triggers a Use-After-Free via TypedArray.sort() in Microsoft Edge by passing a compareFunction that returns an object with a valueOf property (instead of a number), which is used to detach the underlying ArrayBuffer mid-sort via postMessage transfer. ↗
- →The UAF is triggered by transferring the ArrayBuffer backing the TypedArray to another context (via postMessage) inside the sort comparator, detaching the buffer while the sort is still operating on it. ↗
- →Look for JavaScript creating a large ArrayBuffer (e.g. 0x10010 bytes), wrapping it in a TypedArray, and calling .sort() with a comparator that invokes postMessage with the buffer in the transfer list. ↗
- →CVE-2016-7288 is classified as 'Exploitation More Likely' by Microsoft, indicating active weaponization risk; prioritize detection on Microsoft Edge scripting engine activity. ↗
- ·The exploit PoC targets Microsoft Edge specifically (MS16-145); the MSRC advisory also references Internet Explorer rendering engine via hosted ActiveX controls, broadening the attack surface beyond Edge alone. ↗
- ·The localhost URL (http://127.0.0.1) in the PoC is a proof-of-concept artifact for same-origin postMessage transfer; real-world exploitation would use an attacker-controlled origin. ↗

CVE-2016-7288 [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
