CVE-2020-1570: 
vulnerability analysis and mitigation

A remote code execution vulnerability (CVE-2020-1570) exists in Internet Explorer's scripting engine, specifically in how it handles objects in memory. This vulnerability was discovered and reported to Microsoft in 2019, with the CVE being assigned on November 4, 2019. The vulnerability affects various versions of Internet Explorer and multiple Windows operating systems (NVD).

The vulnerability is classified as an Out-of-bounds Write (CWE-787) with a CVSS v3.1 Base Score of 7.5 (HIGH) and attack vector parameters of CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H. The issue stems from memory corruption in the scripting engine that could allow arbitrary code execution in the context of the current user (NVD).

If successfully exploited, an attacker could gain the same user rights as the current user. In cases where the user has administrative privileges, the attacker could take complete control of the affected system, allowing them to install programs, view, change, or delete data, and create new accounts with full user rights (CVE).

The vulnerability can be exploited through multiple attack vectors: hosting a specially crafted website and convincing users to view it, embedding a malicious ActiveX control marked as 'safe for initialization' in an application or Microsoft Office document, or taking advantage of compromised websites that accept or host user-provided content or advertisements (NVD).

Microsoft has addressed this vulnerability by modifying how the scripting engine handles objects in memory through a security update. Users are advised to apply the latest security patches to mitigate this vulnerability (NVD).
