Remote Code Execution via Unsafe Class Loading in Amazon Redshift JDBC Driver Connection Parameters

Summary

Unsafe reflection in the connection parameter and credentials profile handling of Amazon Redshift JDBC Driver before 2.3.0 might allow an actor who can influence the JDBC connection URL or the AWS credentials profile to execute arbitrary code in the application context, provided a suitable class is available on the application classpath. To remediate this issue, users should upgrade to version 2.3.0 or later.

Remediation

1. Inventory every AWS amazon-redshift-jdbc-driver deployment, including staging.
2. Upgrade AWS amazon-redshift-jdbc-driver to 2.3.0.
3. Confirm the running version after the upgrade.
