Preface: Businesses that deploy Akka with .NET span industries like investment banking, retail, healthcare, and social media, and are often found in sectors requiring high-throughput, low-latency systems such as finance, e-commerce, and online gaming. Companies have used Akka.NET to build microservices, power AI solutions, and create resilient, scalable distributed systems that benefit from its actor-based model for fault tolerance and real-time responsiveness.
Background: Akka.NET is a .NET port of the original Akka project, which originated in the Scala/Java community. It provides an idiomatic .NET implementation of the Actor Model, enabling developers to build highly concurrent, distributed, and fault-tolerant systems using C# and F#.
In C# and F#, “System” typically refers to the System namespace, which is a fundamental part of the .NET Framework and .NET Core. This namespace provides access to core functionality that is essential for almost any .NET application, regardless of whether it’s written in C# or F#.
What Happens Due to the Flaw?
1-Malicious Client connects to the cluster over TLS.
2-Because client certificate validation is not enforced, the cluster accepts the connection.
3-The malicious client can:
Send spoofed messages to actors (e.g., fake orders).
Intercept or manipulate actor responses.
Disrupt trading logic or inject latency.
