Version 4.0 only supports TLS 1.0 by default, which is considered insecure by modern standards. It also utilizes the BinaryFormatter , a component now deemed highly risky due to deserialization vulnerabilities. The "4.0.30319" Confusion
Original RTM did not enforce proper ciphertext integrity for view state. Only fixed with the ASP.NET security update (MS10-070) released in September 2010—meaning unpatched RTM is vulnerable.
Over the past decade, security researchers have uncovered numerous flaws. Below are the most impactful vulnerabilities that affect version 4.0.30319.
