CoreWCF is a port of the service side of Windows Communication Foundation (WCF) to .NET Core. Prior to 1.8.1 and 1.9.1, a CoreWCF service listening on a Kafka topic stops processing new records from that topic when KafkaTransportPump receives a null-value tombstone record, causing a persistent endpoint denial of service for attackers with produce permission. This issue is fixed in versions 1.8.1 and 1.9.1.

Affected: NuGet: CoreWCF.Kafka

### Impact A CoreWCF service is running and listening on a Kafka topic receiving a null-value record will stop processing new records from that topic.

#### Preconditions The attacker has produce/write permission on a topic that CoreWCF is consuming from. If the broker permits anonymous publishes, no authentication is required.

### Patches Fixed in CoreWCF v1.8.1 and v1.9.1

### Workarounds Only allow authenticated writes to a topic
