CVE Number Vulnerability Product Severity Date
CVE-2020-0606 .NET Framework Remote Code Execution Vulnerability .NET Framework Critical 15-01-2020

Technical Information

Brief overview of the risk:

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.

 

Detailed Information on the risk:

Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of .NET Framework. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file.
The security update addresses the vulnerability by correcting how .NET Framework checks the source markup of a file.
