This page is sending dangerous requests since it is using a rich text editor that post HTML. This was worked around before by putting
ValidateRequest="false" in the page declaration.This seems to be ignored now in .NET4! Really I should be changing TinyMCE to be posting BBCode and replacing it with proper HTML on the server... but... I'm not since this is only for trusted internal users... and I can't be bothered ;)
Workaround
requestValidationMode="2.0" needs to be added to the httpRuntime element of the<system.web> section of the web.config.

ReplyDeleteThe article explains a common issue encountered when upgrading from ASP.NET 3.5 to .NET 4, where enhanced request validation triggers an HttpRequestValidationException for pages that accept HTML input from controls such as TinyMCE. By describing the underlying cause and providing a practical workaround using the requestValidationMode="2.0" setting in the web.config file, it offers valuable guidance for developers maintaining legacy ASP.NET applications while balancing compatibility and security.
ReplyDeleteProtecting web applications begins with implementing secure input validation and properly handling user-supplied data to prevent security vulnerabilities. Understanding request validation, configuration management, and secure coding practices enables developers to build resilient applications that defend against malicious input and common web attacks. Students and professionals interested in strengthening these application security concepts can explore Information Security Projects for Final Year, which provide practical experience in securing modern software systems.
Application security forms a critical part of the broader cybersecurity landscape, where secure configuration, vulnerability mitigation, and defensive programming help protect enterprise applications and sensitive information. Building expertise in cybersecurity enables developers to design systems that remain secure while adapting to evolving technology platforms and threat landscapes.
