Security Update for .NET Core SDK (Sep 2019)

high Nessus Plugin ID 128772

Synopsis

The remote Windows host is affected by multiple .NET Core SDK vulnerabilities.

Description

The Microsoft .NET Core SDK installation on the remote host is version 2.1.x < 2.1.509, or 2.1.606 or 2.1.802, 2.2.x < 2.2.109 or 2.2.206 or 2.2.302.
It is, therefore, affected by multiple vulnerabilities:

- A denial of service vulnerability when .Net Core improperly handles web requests. An unauthenticated, remote attacker could exploit this issue, to cause a denial of service attack against a .Net Core web application. (CVE-2019-1301)

- An elevation of privilege vulnerability that could lead to a content injection attack enabling an attacker to run a script in the context of the logged-on user. 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. (CVE-2019-1302)

Solution

Refer to vendor documentation.
