CVE-2023-34050

Disclosure Date: October 19, 2023
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

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
