Details

Why is the severity for this CVE rated as Moderate, but the CVSS score is higher than normal?
Per our severity guidelines, the amount of user interaction or preconditions required to allow this sort of exploitation downgraded the severity, specifically it says, "If a bug requires more than a click, a key press, or several preconditions, the severity will be downgraded". The CVSS scoring system doesn't allow for this type of nuance.

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 first prepare the target so that it uses Edge in Internet Explorer Mode.

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, the attack complexity is high (AC:H). What does that mean for this vulnerability?

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.
