How to Fix CVE-2021-36372

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

org.apache.ozone:ozone-main fixed: 1.2.0 
<dependency>
    <groupId>org.apache.ozone</groupId>
    <artifactId>ozone-main</artifactId>
    <version>1.2.0</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=org.apache.ozone

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2021-36372, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.ozone

Analyze the terminal output to locate any version of Ozone main in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.2.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.ozone 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-273: Improper Check for Dropped Privileges, where the product attempts to drop privileges but does not check or incorrectly checks to see if the drop succeeded. In Ozone main, 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

In Apache Ozone versions prior to 1.2.0, Initially generated block tokens are persisted to the metadata database and can be retrieved with authenticated users with permission to the key. Authenticated users may use them even after access is revoked.
