Detection & IOCsextracted from sources · hover to see the quote
- →Exploit uses a specially crafted NameList allocation of exactly 0x970 bytes (via a 570-char repeated 'a' property name) to reclaim freed memory; heap allocations of size 0x970 in jscript.dll context during IE scripting may indicate exploitation attempts. ↗
- →Exploit targets IE in 64-bit single process mode enabled via TabProcGrowth registry flag; monitor for unusual TabProcGrowth registry modifications that force IE into single-process mode, which may indicate exploit staging. ↗
- →The exploit uses a magic marker value 0x1337 embedded in a specially crafted property name string to identify the reallocated object; scanning JScript heap or memory dumps for this marker alongside UAF patterns may indicate active exploitation. ↗
- →Call stack for exploitation passes through jscript!VAR::InvokeByDispID, jscript!CScriptRuntime::Run, and MSHTML!CActiveScriptHolder::ParseScriptText; this call chain in crash telemetry or ETW traces is indicative of in-the-wild exploitation of this UAF. ↗
- ·The published exploit (Exploit-DB 45279) is incomplete — it only leaks a heap address and does not achieve full code execution; structure sizes and offsets are specific to 64-bit single-process IE mode and would differ in the default 32-bit process. ↗
- ·Microsoft assessed exploitation as 'More Likely' for both latest and older software releases at time of patch, despite no confirmed in-the-wild exploitation at disclosure. ↗
- ·The exploit reliability note mentions that triggering the Low Fragmentation Heap (LFH) for the 0x970 allocation size was not implemented and would likely improve reliability. ↗

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
