How to Fix CVE-2021-29052

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: Latest secure release 
<dependency>
    <groupId>com.liferay.portal</groupId>
    <artifactId>release.portal.bom</artifactId>
    <version>Latest secure release</version>
</dependency>
com.liferay.portal:release.dxp.bom fixed: 7.3.10.fp1 
<dependency>
    <groupId>com.liferay.portal</groupId>
    <artifactId>release.dxp.bom</artifactId>
    <version>7.3.10.fp1</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-2021-29052, 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 7.3.10.fp1), 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-276: Incorrect Default Permissions, where during installation, installed file permissions are set to allow anyone to modify those files. 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.

Source Advisory Statement

The Data Engine module in Liferay Portal 7.3.0 through 7.3.5, and Liferay DXP 7.3 before fix pack 1 does not check permissions in DataDefinitionResourceImpl.getSiteDataDefinitionByContentTypeByDataDefinitionKey, which allows remote authenticated users to view DDMStructures via GET API calls.
