CVE-2020-1056 Microsoft Edge Elevation of Privilege Vulnerability Microsoft Edge Critical 13-05-2020

Technical Information

Brief overview of the risk:

An elevation of privilege vulnerability exists when Microsoft Edge does not properly enforce cross-domain policies, which could allow an attacker to access information from one domain and inject it into another domain.

 

Detailed Information on the risk:
In a web-based attack scenario, an attacker could host a website that is used to 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 users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action. For example, an attacker could trick users into clicking a link that takes them to the attacker’s site. An attacker who successfully exploited this vulnerability could elevate privileges in affected versions of Microsoft Edge.
The security update addresses the vulnerability by helping to ensure that cross-domain policies are properly enforced in Microsoft Edge.
