CVE-2023-34040— Java Deserialization vulnerability in Spring-Kafka When Improperly Configured

Java Deserialization vulnerability in Spring-Kafka When Improperly Configured

In Spring for Apache Kafka 3.0.9 and earlier and versions 2.9.10 and earlier, a possible deserialization attack vector existed, but only if unusual configuration was applied. An attacker would have to construct a malicious serialized object in one of the deserialization exception record headers. Specifically, an application is vulnerable when all of the following are true: * The user does not configure an ErrorHandlingDeserializer for the key and/or value of the record * The user explicitly sets container properties checkDeserExWhenKeyNull and/or checkDeserExWhenValueNull container properties to true. * The user allows untrusted sources to publish to a Kafka topic By default, these properties are false, and the container only attempts to deserialize the headers if an ErrorHandlingDeserializer is configured. The ErrorHandlingDeserializer prevents the vulnerability by removing any such malicious headers before processing the record.

可信数据的反序列化

Spring Framework 代码问题漏洞

Spring Framework是美国Spring团队的一套开源的Java、JavaEE应用程序框架。该框架可帮助开发人员构建高质量的应用。 Spring Framework 存在安全漏洞，该漏洞源于存在反序列化漏洞，允许容器在配置了ErrorHandlingDeserializer的情况下反序列化标头。受影响的产品和版本：Spring for Apache Kafka 3.0.9及之前版本，2.9.10及之前版本。
