Security Update for .NET Core (January 2020)

high Nessus Plugin ID 132993

Language:

Synopsis

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

Description

The Microsoft .NET Core installation on the remote host is version 3.0.x < 3.0.2 or 3.1.x < 3.1.1. It is, therefore, affected by multiple vulnerabilities:

- A remote code execution vulnerability exists in .NET software when the software fails to check the source markup of a file. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. (CVE-2020-0605, CVE-2020-0606)

Solution

Refer to vendor documentation.
