How to Fix CVE-2023-42278

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

cn.hutool:hutool-core fixed: 5.8.22 
<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-core</artifactId>
    <version>5.8.22</version>
</dependency>
cn.hutool:hutool-json fixed: 5.8.22 
<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-json</artifactId>
    <version>5.8.22</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=cn.hutool

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-42278, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=cn.hutool

Analyze the terminal output to locate any version of Hutool core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.8.22), your application is affected.

Note: The mvn dependency:tree -Dincludes=cn.hutool 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-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow'), where the product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer. In Hutool core, 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

hutool v5.8.21 was discovered to contain a buffer overflow via the component `JSONUtil.parse()`.
