How to Fix CVE-2022-42003

To remediate this vulnerability, upgrade all affected Jackson databind dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.fasterxml.jackson.core:jackson-databind fixed: 2.12.7.1 
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.12.7.1</version>
</dependency>
com.fasterxml.jackson.core:jackson-databind fixed: 2.13.4.2 
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.13.4.2</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=com.fasterxml.jackson.core

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-42003, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.fasterxml.jackson.core

Analyze the terminal output to locate any version of Jackson databind in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.12.7.1), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.fasterxml.jackson.core 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 Jackson databind, 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.

Source Advisory Statement

In FasterXML jackson-databind 2.4.0-rc1 until 2.12.7.1 and in 2.13.x before 2.13.4.2 resource exhaustion can occur because of a lack of a check in primitive value deserializers to avoid deep wrapper array nesting, when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled. This was patched in 2.12.7.1, 2.13.4.2, and 2.14.0. Commits that introduced vulnerable code are https://github.com/FasterXML/jackson-databind/commit/d499f2e7bbc5ebd63af11e1f5cf1989fa323aa45, https://github.com/FasterXML/jackson-databind/commit/0e37a39502439ecbaa1a5b5188387c01bf7f7fa1, and https://github.com/FasterXML/jackson-databind/commit/7ba9ac5b87a9d6ac0d2815158ecbeb315ad4dcdc. Fix commits are https://github.com/FasterXML/jackson-databind/commit/cd090979b7ea78c75e4de8a4aed04f7e9fa8deea and https://github.com/FasterXML/jackson-databind/commit/d78d00ee7b5245b93103fef3187f70543d67ca33. The `2.13.4.1` release does fix this issue, however it also references a non-existent jackson-bom which causes build failures for gradle users. See https://github.com/FasterXML/jackson-databind/issues/3627#issuecomment-1277957548 for details. This is fixed in `2.13.4.2` which is listed in the advisory metadata so that users are not subjected to unnecessary build failures
