high Nessus Plugin ID 105730

Language:

Synopsis

The remote Windows host is affected by a .NET Core runtime vulnerability.

Description

The remote Windows host has an installation of .NET Core with a version less than 2.0.5. Therefore, the host is affected by multiple vulnerabilities :

- A security feature bypass in X509 Certificate Validation allows an attacker to present a certificate that is marked as invalid for a specific use, but a component uses it for that purpose. (CVE-2018-0786)

- A denial of service vulnerability exists due to improper processing of XML documents. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to a .NET Core application. (CVE-2018-0764)

Solution

Update to .NET Core Runtime version 1.09 / 1.1.6 / 2.0.5 or later.
