CVE-2023-34050 Information

Description

In spring AMQP versions 1.0.0 to 2.4.16 and 3.0.0 to 3.0.9 allowed list patterns for deserializable class names were added to Spring AMQP allowing users to lock down deserialization of data in messages from untrusted sources; however by default when no allowed list was provided all classes could be deserialized.

Specifically an application is vulnerable if

 the
 SimpleMessageConverter or SerializerMessageConverter is used

 the user
 does not configure allowed list patterns

 untrusted
 message originators gain permissions to write messages to the RabbitMQ
 broker to send malicious content
