Spring AMQP Deserialization Vulnerability

Published Oct 19, 2023 · Updated Sep 12, 2024 · Assigned by vmware

Vendor: Spring Product: Spring AMQP

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
