Microsoft Security Advisory CVE-2024-21319: .NET Denial of Service Vulnerability
Executive summary
Microsoft is releasing this security advisory to provide information about a vulnerability in the ASP.NET Core project templates. This advisory also provides guidance on what developers can do to update their applications to address this vulnerability.
A Denial of Service vulnerability exists in ASP.NET Core project templates which utilize JWT-based authentication tokens. This vulnerability allows an unauthenticated client to consume arbitrarily large amounts of server memory, potentially triggering an out-of-memory condition on the server and making the server no longer able to respond to legitimate requests.

Advisory FAQ
How do I know if I am affected?
If you are you using project templates listed in affected software, you may be exposed to the vulnerability.
How do I fix the issue?
For existing projects:
If you ever created any of these projects via the dotnet new command or via Visual Studio's File -> New Project gesture, and if you enabled federated authentication at project creation time, your project may be vulnerable. To remediate the vulnerability, use your package manager to update any references you may have to the Microsoft.AspNetCore.Authentication.JwtBearer, Microsoft.AspNetCore.Authentication.OpenIdConnect, and Microsoft.IdentityModel.JsonWebTokens packages to their respective latest versions.
If your project does not reference any of those three packages, you are not exposed to this vulnerability.
For new projects:
To remediate this issue please update to the latest SDK listed below. Simply installing the SDK update is not sufficient to remediate projects already-created / already-deployed projects which existed prior to this update being released.
dotnet --info
command. You will see output like the following;.NET 6.0, .NET 7.0, .NET 8.0 updates are also available from Microsoft Update. To access this either type "Check for updates" in your Windows search, or open Settings, choose Update & Security and then click Check for Updates.
Once you have installed the updated runtime or SDK, restart your apps for the update to take effect.
Additionally, if you've deployed self-contained applications targeting any of the impacted versions, these applications are also vulnerable and must be recompiled and redeployed.
