How to Fix CVE-2022-40929

To remediate this vulnerability, upgrade all affected Xxl job 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.

com.xuxueli:xxl-job-core fixed: Latest secure release 
<dependency>
    <groupId>com.xuxueli</groupId>
    <artifactId>xxl-job-core</artifactId>
    <version>Latest secure release</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.xuxueli

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-40929, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.xuxueli

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

Note: The mvn dependency:tree -Dincludes=com.xuxueli 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-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Xxl job 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

XXL-JOB versions 2.2.0 and prior contain a Command execution vulnerability in background tasks. NOTE: this is disputed because the issues/4929 report is about an intended and supported use case (running arbitrary Bash scripts on behalf of users).
