Detection & IOCsextracted from sources · hover to see the quote
- →Vulnerability exists in the scripting engine's handling of objects in memory in Internet Explorer; look for exploitation via specially crafted websites or embedded ActiveX controls marked 'safe for initialization' in Office documents or applications hosting the IE rendering engine. ↗
- →Monitor for suspicious ActiveX control instantiation within Office documents or IE-hosted rendering engine contexts, particularly controls marked 'safe for initialization', as this is a documented attack vector for CVE-2016-7242. ↗
- →Monitor for users being directed to attacker-controlled or compromised websites via Internet Explorer, especially sites hosting user-provided content or advertisements, as these are delivery vectors for this vulnerability. ↗
- ·CVE-2016-7242 affects the scripting engine in Internet Explorer (memory object handling), while the closely related CVE-2016-7243 affects the Chakra JavaScript engine in Microsoft Edge — these are distinct vulnerabilities despite similar descriptions. Ensure detections and patches target the correct browser/engine. ↗
- ·Microsoft assessed exploitation as 'More Likely' for the latest software release at time of disclosure; no public exploit or in-the-wild exploitation was confirmed at time of advisory publication. ↗

CVE-2016-7242 [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
