CVE-2024-32888

The Amazon JDBC Driver for Redshift is a Type 4 JDBC driver that provides database connectivity through the standard JDBC application program interfaces (APIs) available in the Java Platform, Enterprise Editions. Prior to version 2.1.0.28, SQL injection is possible when using the non-default connection property preferQueryMode=simple in combination with application code which has a vulnerable SQL that negates a parameter value. There is no vulnerability in the driver when using the default, extended query mode. Note that preferQueryMode is not a supported parameter in Redshift JDBC driver, and is inherited code from Postgres JDBC driver. Users who do not override default settings to utilize this unsupported query mode are not affected. This issue is patched in driver version 2.1.0.28. As a workaround, do not use the connection property preferQueryMode=simple. (NOTE: Those who do not explicitly specify a query mode use the default of extended query mode and are not affected by this issue.)
