Authenticated security-control bypass via undisclosed flaw
Published Nov 14, 2023 · Updated Oct 8, 2025
Security-feature bypass in Microsoft .NET Framework allows remote authenticated users to bypass ASP.NET application security controls. Microsoft has not disclosed the affected ASP.NET locus or the operation that mishandles untrusted input. Network access with a low-privileged account is required, no user interaction is needed, and successful exploitation can expose or alter protected data and interrupt service.
