How to Fix CVE-2022-45347

To remediate this vulnerability, upgrade all affected Shardingsphere proxy 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.shardingsphere:shardingsphere-proxy fixed: 5.3.0 
<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>shardingsphere-proxy</artifactId>
    <version>5.3.0</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.shardingsphere

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-45347, inspect your build dependencies using the Maven Dependency Plugin:

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

Analyze the terminal output to locate any version of Shardingsphere proxy in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.3.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.shardingsphere 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-459: Incomplete Cleanup, where the product does not properly "clean up" and remove temporary or supporting resources after they have been used. In Shardingsphere proxy, 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

Apache ShardingSphere-Proxy prior to 5.3.0 when using MySQL as database backend didn't cleanup the database session completely after client authentication failed, which allowed an attacker to execute normal commands by constructing a special MySQL client. This vulnerability has been fixed in Apache ShardingSphere 5.3.0.
