CVE-2023-34040: Spring Framework Spring-Kafka Has Java Deserialization Vulnerability Vulnerability
HIGHCVE-2023-34040 is a HIGH (CVSS 7.8) spring-kafka has java deserialization vulnerability vulnerability (CWE-502: Deserialization of Untrusted Data) affecting Spring Framework libraries in the Maven ecosystem. The issue involves spring-kafka has java deserialization vulnerability when improperly configured. Remediation is available by upgrading affected packages to version 2.9.11, 3.0.10.
CVE-2023-34040 at a Glance
Security Impact
CVSS: 7.8
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2023-34040
To remediate this vulnerability, upgrade all affected Spring Framework dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.springframework.kafka</groupId>
<artifactId>spring-kafka</artifactId>
<version>2.9.11</version>
</dependency><dependency>
<groupId>org.springframework.kafka</groupId>
<artifactId>spring-kafka</artifactId>
<version>3.0.10</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.springframework.kafkaHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2023-34040, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.springframework.kafkaAnalyze the terminal output to locate any version of Spring Framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.9.11), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.springframework.kafka command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Spring Framework, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "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.\n\nSpecifically, an application is vulnerable when all of the following are true:\n\n * The user does not configure an ErrorHandlingDeserializer for the key and/or value of the record\n * The user explicitly sets container properties checkDeserExWhenKeyNull and/or checkDeserExWhenValueNull container properties to true.\n * The user allows untrusted sources to publish to a Kafka topic\n\n\nBy 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.",
