How to Fix CVE-2023-51075

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: 5.8.24 
<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-core</artifactId>
    <version>5.8.24</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-2023-51075, 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 5.8.24), 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-835: Loop with Unreachable Exit Condition ('Infinite Loop'), where the product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop. 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-core v5.8.23 was discovered to contain an infinite loop in the StrSplitter.splitByRegex function. This vulnerability allows attackers to cause a Denial of Service (DoS) via manipulation of the first two parameters.
