.NET Framework Remote Code Execution Vulnerability
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.
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.
FAQ
There are two updates for .NET Framework 3.5 installed on Windows 10 version 1809 and Windows Server 2019. How do I know which update I need to install?
The security updates for Windows 10 version 1809 and Windows Server 2019 include both .NET Framework 3.5 and 4.7.2 or 4.8. Customers running these versions of Windows 10 need to determine if they are also running .NET Framework 4.7.2 or .NET Framework 4.8. Install the security update that includes that second version of .NET Framework.
