CVE-2020-0646
In short
Microsoft .NET Framework fails to properly validate user input, allowing attackers to execute malicious code remotely on affected systems. This is a critical vulnerability because it can give attackers complete control over the computer without needing special access.
Technical detail
A remote code execution vulnerability in .NET Framework's input validation mechanism (CWE-91: XML Injection) allows unauthenticated attackers to execute arbitrary code through specially crafted input, typically via network-accessible .NET applications. The vulnerability requires no user interaction and affects systems running vulnerable .NET Framework versions.
Summary generated and translated by AI from the official description.
A remote code execution vulnerability exists when the Microsoft .NET Framework fails to validate input properly, aka '.NET Framework Remote Code Execution Injection Vulnerability'.
