The Microsoft .NET Core SDK installation on the remote host is version 2.1.x < 2.1.508 or 2.1.605 or 2.1.701, 2.2.x < 2.2.108 or 2.2.205 or 2.2.301.
It is, therefore, affected by a spoofing vulnerability that could lead to an open redirect.
An unauthenticated, remote attacker could exploit this issue, via a link that has a specially crafted URL, and convince the user to click the link that will redirect a targeted user to a malicious website
