CVE-2018-21234: Jodd json Deserialization Of Untrusted Data Vulnerability
CRITICALCVE-2018-21234 is a CRITICAL (CVSS 9.8) deserialization of untrusted data vulnerability (CWE-502: Deserialization of Untrusted Data) affecting Jodd json libraries in the Maven ecosystem. The issue involves deserialization of untrusted data in jodd. Remediation is available by upgrading affected packages to version 5.0.4.
CVE-2018-21234 at a Glance
Security Impact
CVSS: 9.8
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2018-21234
To remediate this vulnerability, upgrade all affected Jodd json 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.jodd</groupId>
<artifactId>jodd-json</artifactId>
<version>5.0.4</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.joddHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2018-21234, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.joddAnalyze the terminal output to locate any version of Jodd json in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.0.4), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.jodd 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 Jodd json, 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.
