CVE-2020-11972Network attack vector

Remote code execution via RabbitMQ message deserialization

Published May 14, 2020 · Updated Aug 4, 2024

Deserialization of untrusted data in Apache Camel RabbitMQ 2.22.x through 2.25.0 and 3.0.0 through 3.1.0 allows remote attackers to execute code. RabbitMQMessageConverter.populateMessageBody invokes deserializeBody when a message carries the CamelSerialize header because serialization is enabled by default. Exploitation requires access to publish to a consumed RabbitMQ destination and a usable gadget on the application classpath; code runs in the Camel process.
