- →Trigger condition: a DataView object from one iframe context accesses optimized JIT-compiled function code belonging to another context after that context has been closed (f.src = 'about:blank'), resulting in a use-after-free in chakra.dll. ↗
- →The vulnerability is triggered via a cross-context DataView object that bypasses CrossSite wrapping; the MarshalToScriptContext method does not wrap the ArrayBuffer returned by DataView, allowing the unwrapped object to escape its context. ↗
- →PoC attack pattern: iframe is created, cross-context eval runs a function 'opt' that is JIT-optimized in a loop, then the iframe is navigated to about:blank to free the JIT code, followed by calling opt() from the parent context to trigger UAF. ↗
- ·Analysis and assembly offsets are specific to chakra.dll version 11.00.14393.447; behavior and offsets will differ on other versions. ↗
- ·Microsoft's own advisory notes the exploit status as 'Publicly Disclosed: No; Exploited: No' at time of patch, meaning no in-the-wild exploitation was confirmed. ↗

CVE-2018-0946 [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 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 specially cra

An Analysis of the DLL Address Leaking Trick used by the “Double Kill” Internet Explorer Zero-Day exploit (CVE-2018-8174)
By Dehui Yin | August 06, 2018
“Double Kill” is an Internet Explorer(IE) Zero-Day exploit which was discovered in the wild and fixed in the Microsoft May Patch. It exploits a use-after-free vulnerability of vbscript.dll to execute arbitrary code when a vulnerable system browses a malicious web page via IE. Multiple exploit kits have already added this exploit, and it is still active in the wild.
This use-after-free bug causes a type confusion in vbscript.dll, which allows the attacker to access and overwrite the whole user space memory address. However, before the shellcode can be finally executed, the attacker has to get the address o

An Analysis of the Use-After-Free Bug in the Microsoft Edge Chakra Engine (CVE-2018-0946)
By Dehui Yin | June 28, 2018
Microsoft fixed an use-after-free bug in the Edge Chakra Engine in the May 2018 Patch. This bug (CVE-2018-0946) causes the Chakra Engine to access a freed function address that can possibly be exploited to execute arbitrary code when a vulnerable system browses a malicious web page via Microsoft Edge.
This use-after-free bug occurs when the Chakra Engine tries to execute the optimized function code generated by the just-in-time (JIT) compiler, which has already been freed when closing the related context. In this post, the team at FortiGuard Labs looks deeply into the Microsoft Edge Chakra Engine assembly codes to expose the root cause of

An Analysis of Microsoft Edge Chakra NewScObjectNoCtor Array Type Confusion (CVE-2018-0838)
By Dehui Yin | May 18, 2018
CVE-2018-0838 is one of the ‘type confusion’ bugs in the Microsoft Edge Chakra Engine that was fixed by Microsoft three months ago. This bug causes memory corruption and can possibly be exploited to execute arbitrary code when a vulnerable system browses a malicious web page via Microsoft Edge.
This type confusion bug occurs when the codes generated by the Chakra just-in-time (JIT) java compiler change the property value of a newly converted JavascriptArray object without validation. In this post, the team at FortiGuard Labs looks deeply into the Microsoft Edge Chakra Engine assembly codes to expose the root cause of this vulnerability.
