Detection & IOCsextracted from sources · hover to see the quote
- →The exploit triggers the vulnerability by registering a DOMNodeRemoved event listener and then calling textarea.defaultValue assignment followed by form.reset() inside the handler, causing a use-after-free / memory disclosure in edgehtml.dll. Monitor for JavaScript patterns combining DOMNodeRemoved event listeners with textarea.defaultValue mutation and form reset calls. ↗
- →The crash occurs in edgehtml!Ordinal125+0x6446c when reading from a freed heap allocation, visible via page-heap as a read of a freed DPH_HEAP_BLOCK. The faulting instruction is 'cmp word ptr [r14]' where r14 points into freed memory. Detection via application verifier / page-heap on MicrosoftEdge.exe will surface this as an access to freed memory. ↗
- →The freed allocation is traced back through edgehtml!CreateWebDriverAdapter and edgehtml!Ordinal107 call chains involving RtlReAllocateHeap. Heap corruption telemetry or ETW heap tracing on MicrosoftEdge.exe showing RtlReAllocateHeap followed by access to freed block at the same address is indicative of exploitation. ↗
- ·The exploit PoC uses a recursion guard (n==5) to prevent infinite recursion in the DOMNodeRemoved event handler; real-world weaponized variants may use different iteration counts or alternative event types. ↗
- ·Microsoft's advisory notes exploitation requires user interaction — an attacker must trick the user into visiting an attacker-controlled or compromised website; drive-by exploitation without user action is not possible. ↗
- ·Microsoft rates this as 'Exploitation More Likely' for the latest software release at time of disclosure, despite no confirmed in-the-wild exploitation at time of patch. ↗

CVE-2017-8652 [MEDIUM] Microsoft Edge based on Edge HTML Information Disclosure Vulnerability
Microsoft Edge based on Edge HTML Information Disclosure Vulnerability
Description: An information disclosure vulnerability exists when Microsoft Edge based on Edge HTML improperly handles objects in memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system.
To exploit the vulnerability, in a web-based attack scenario, an attacker could host a website in an attempt to exploit the vulnerability. In addition, compromised websites and websites that accept or host user-provided content could contain specially crafted content that could exploit the vulnerability. However, in all cases an attacker would have no way to force a user to view the attacker-controlled content. Instead, an attacker would have to convince a user to
