漏洞描述

2023年10月 Spring官方披露 CVE-2023-34050 Spring AMQP反序列化漏洞漏洞。由于 SimpleMessageConverter 或 SerializerMessageConverter 默认未配置白名单，导致可以反序列化任意类。新版本中在未配置白名单的情况下则不允许反序列化任意类。

解决建议

1、不允许不受信任的源访问RabbitMQ服务器
2、版本低于2.4.17的用户应升级到2.4.17
3、使用3.0.0至3.0.9版本的用户应升级至3.0.10

CVE-2023-34050 Spring AMQP Deserialization Vulnerability

MEDIUM | OCTOBER 18, 2023 | CVE-2023-34050

Description

In 2016, 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, and 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

Affected Spring Products and Versions

Spring AMQP
- 1.0.0 to 2.4.16
- 3.0.0 to 3.0.9

Mitigation

Do not allow untrusted sources to access the RabbitMQ server
Users with versions less that 2.4.17 should upgrade to 2.4.17
Users using versions 3.0.0 to 3.0.9 should upgrade to 3.0.10

Spring Boot dependency management will pull in the corrected versions, starting with Boot versions 2.7.17, 3.0.12, 3.1.5, and 3.2.0.

Allowed class name patterns are now required.

However, users who wish to revert to the previous behavior of trusting all, can set a global environment property or system property; refer to the Java Deserialization documentation section
