How to Fix GHSA-3qpm-h9ch-px3c

To remediate this vulnerability, upgrade all affected Powernukkit 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.powernukkit:powernukkit fixed: 1.5.2.1 
<dependency>
    <groupId>org.powernukkit</groupId>
    <artifactId>powernukkit</artifactId>
    <version>1.5.2.1</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.powernukkit

How to Check if You Are Affected

To determine whether your Java application is affected by GHSA-3qpm-h9ch-px3c, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.powernukkit

Analyze the terminal output to locate any version of Powernukkit in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.5.2.1), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.powernukkit 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-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Powernukkit, 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

### Summary The version used of Log4j, the library used for logging by PowerNukkit, is subject to a remote code execution vulnerability via the ldap JNDI parser. It's well detailed at [CVE-2021-44228](https://github.com/advisories/GHSA-jfh8-c2jp-5v3q) and CVE-2021-45105(https://github.com/advisories/GHSA-p6xc-xr62-6r2g). ### Impact Malicious client code could be used to send messages and cause remote code execution on the server. ### Patches PowerNukkit `1.5.2.1` is a patch-release that only updates the Log4j version to `2.17.0` and should be used instead of `1.5.2.0`. All versions prior to `1.5.2.1` are affected and are not patched. ### Workarounds If you can't upgrade, you can use the `-Dlog4j2.formatMsgNoLookups=true` startup argument as remediation, as this prevents the vulnerability from happening. ### References https://github.com/advisories/GHSA-jfh8-c2jp-5v3q https://github.com/advisories/GHSA-p6xc-xr62-6r2g ### For more information If you have any questions or comments about this advisory: * Open an issue in [the PowerNukkit repository](https://github.com/PowerNukkit/PowerNukkit/issues)
