CVE-2024-21643 – Microsoft.IdentityModel.Protocols.SignedHttpRequest remote code execution vulnerability

https://notcve.org/view.php?id=CVE-2024-21643

IdentityModel Extensions for .NET provide assemblies for web developers that wish to use federated identity providers for establishing the caller's identity. Anyone leveraging the `SignedHttpRequest`protocol or the `SignedHttpRequestValidator`is vulnerable. Microsoft.IdentityModel trusts the `jku`claim by default for the `SignedHttpRequest`protocol. This raises the possibility to make any remote or local `HTTP GET` request. The vulnerability has been fixed in Microsoft.IdentityModel.Protocols.SignedHttpRequest. • https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/releases/tag/6.34.0 https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/releases/tag/7.1.2 https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/security/advisories/GHSA-rv9j-c866-gp5h https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/wiki/jkucve • CWE-94: Improper Control of Generation of Code ('Code Injection') •
