How to Fix GHSA-28gg-8qqj-fhh5

To remediate this vulnerability, upgrade all affected Geoip processor 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.opensearch.dataprepper.plugins:geoip-processor fixed: 2.12.2 
<dependency>
    <groupId>org.opensearch.dataprepper.plugins</groupId>
    <artifactId>geoip-processor</artifactId>
    <version>2.12.2</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.opensearch.dataprepper.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by GHSA-28gg-8qqj-fhh5, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.opensearch.dataprepper.plugins

Analyze the terminal output to locate any version of Geoip processor in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.12.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.opensearch.dataprepper.plugins 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-295: Improper Certificate Validation, where the product does not validate, or incorrectly validates, a certificate. In Geoip processor, 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

### Impact The GeoIP processor and Kafka source and buffer were using the deprecated "SSL" protocol identifier when creating SSL contexts, potentially allowing the use of insecure SSL protocols instead of modern TLS versions. Multiple Data Prepper plugins used `SSLContext.getInstance("SSL")` which could potentially allow the use of deprecated SSL protocols (SSLv2, SSLv3) that have known security vulnerabilities. While modern Java implementations typically default to secure TLS versions even with the "SSL" identifier, explicitly using "TLS" ensures that only secure TLS protocols are negotiated. The affected components were: * GeoIP Processor: The `DBSource.initiateSSL()` method used for downloading GeoIP databases from external sources * Kafka Plugin: Both `CustomClientSslEngineFactory` and `InsecureSslEngineFactory` classes used for Kafka client connections This could potentially allow connections to negotiate weaker SSL protocols instead of enforcing modern TLS versions, reducing the security of data transmission. ### Patches Data Prepper 2.12.2 contains a fix for this issue. ### Workarounds If upgrading is not immediately possible: 1. Ensure your Java runtime is configured to disable deprecated SSL protocols 2. Use network-level controls to enforce TLS-only connections 3. Use external tools to verify that deprecated SSL protocols are not allowed.
