Unauthenticated service interruption via HTTP.sys requests
Published Aug 13, 2024 · Updated Jul 10, 2025
Uncontrolled resource consumption in ASP.NET HTTP.sys in Microsoft .NET 8.0 and Visual Studio 2022 allows remote attackers to interrupt service. Microsoft has not published the request characteristic or the exact HTTP.sys resource that is exhausted. Exploitation requires a Windows-hosted ASP.NET application using HTTP.sys and unauthenticated network access; it can make that service unavailable without reported data exposure or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
