Microsoft FAQ (4)
According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?
Successful exploitation of this vulnerability requires an attacker to take additional actions prior to exploitation to prepare the target environment.
According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?
This vulnerability could lead to a browser sandbox escape.
According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?
The user would have to click on a specially crafted URL to be compromised by the attacker.
How could an attacker exploit this vulnerability via the Network?
An attacker could host a specially crafted website designed to exploit the vulnerability through Microsoft Edge and then convince a user to view the website. However, in all cases an attacker would have no way to force a user to view the attacker-controlled content. Instead, an attacker would have to convince a user to take action, typically by an enticement in an email or instant message, or by getting the user to open an attachment sent through email.
