Amazon JDBC Driver for Redshift SQL Injection via line comment generation
Impact
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.
Patch
This issue is patched in driver version 2.1.0.28.
Workarounds
Do not use the connection property preferQueryMode=simple. (NOTE: If you do not explicitly specify a query mode, then you are using the default of extended query mode and are not affected by this issue.)
