How to Fix CVE-2022-42124

To remediate this vulnerability, upgrade all affected Release.portal.bom 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.liferay.portal:release.portal.bom fixed: 7.4.3.5 
<dependency>
    <groupId>com.liferay.portal</groupId>
    <artifactId>release.portal.bom</artifactId>
    <version>7.4.3.5</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.liferay.portal

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-42124, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.liferay.portal

Analyze the terminal output to locate any version of Release.portal.bom in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 7.4.3.5), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.liferay.portal 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-1333: Inefficient Regular Expression Complexity, where the product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential. In Release.portal.bom, 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.
