Software security is not security software. Here we're concerned with topics like authentication, access control, confidentiality, cryptography, and privilege management.

ASP.NET Misconfiguration: Header Checking Disabled

Abstract
Disabling header checking opens the door for attackers to perform header manipulation attacks such as HTTP Response Splitting.
Explanation
By default, the .NET framework prevents new line characters from being sent to APIs that set header values. However, this behavior can be disabled in configuration files by setting the enableHeaderChecking attribute on the <httpRuntime> tag to false.
When this check is disabled, code that allows user input to reach header setting APIs is vulnerable to attacks like HTTP Response Splitting.
