CVE-2020-0832

Vulnerability

Overview The vulnerability is a remote code execution flaw in Internet Explorer's scripting engine, caused by improper handling of objects in memory, leading to memory corruption [1]. This is part of a set of similar scripting engine memory corruption vulnerabilities addressed in the March 2020 Patch Tuesday updates.

Exploitation

An attacker can exploit this vulnerability by hosting a specially crafted website that triggers the memory corruption when a user visits the page using Internet Explorer. The attacker may also leverage compromised websites or ad networks to deliver the exploit. No authentication is required, and user interaction is limited to visiting the malicious site.

Impact

Successful exploitation could allow the attacker to gain the same user rights as the current user. If the user has administrative privileges, the attacker could install programs, view/change/delete data, or create new accounts with full user rights.

Mitigation

Microsoft released a security update to address this vulnerability as part of the March 2020 Patch Tuesday updates [1]. Users should apply the latest updates for Internet Explorer to mitigate the risk.
