CVE-2023-34050Network attack vector

Data alteration and service disruption via unrestricted deserialization

Published Oct 19, 2023 · Updated Sep 12, 2024

Untrusted deserialization in Spring AMQP 1.0.0 through 2.4.16 and 3.0.0 through 3.0.9 allows remote authenticated users to disrupt service. SimpleMessageConverter and SerializerMessageConverter accept serialized message bodies for any class when no allowed-list pattern is configured. Reachability requires permission to publish malicious content to the RabbitMQ broker, and the published impact is limited to data alteration and service disruption.
