Description:

Amazon Redshift JDBC Driver is a Type 4 JDBC driver that provides database connectivity through the standard JDBC application program interfaces (APIs). We identified an issue in Amazon Redshift JDBC Driver versions prior to 2.2.2. Under certain conditions, the driver could load and execute arbitrary classes when processing JDBC connection URL parameters. An actor who can influence the connection URL could potentially execute code in the application context.

Impacted versions: Amazon Redshift JDBC Driver < 2.2.2

Resolution:

This issue has been addressed in Amazon Redshift JDBC Driver version 2.2.2. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.
