Motor.NET < 0.19.0 Denial of Service via JsonNet Deserialization

Impact

Motor.NET before 0.19.0 has a denial-of-service vulnerability via JsonNet deserialization. A remote attacker who can publish to a consumed queue or topic can crash the service by sending valid JSON that doesn't match the handler's expected type. This causes a permanent crash-loop due to an uncaught JsonSerializationException.

Original source description

Motor.NET before 0.19.0 contains an uncaught exception vulnerability in JsonNetDeserializer.Deserialize that allows a remote attacker who can publish to a consumed queue or topic to crash the service permanently by sending structurally valid JSON that does not match the handler's expected type. Attackers can exploit the fact that JsonSerializationException is not caught alongside JsonReaderException and InvalidCastException, causing TypedConsumerService.SingleMessageConsumeAsync to treat the error as CriticalFailure and call StopApplication, which combined with the unacknowledged message being redelivered on restart results in a permanent crash-loop.
