Amazon Redshift Python Connector vulnerable to SQL Injection

Summary

A SQL injection in the Amazon Redshift Python Connector in version 2.1.4 allows a user to gain escalated privileges via schema injection in the get_schemas, get_tables, or get_columns Metadata APIs. Users should upgrade to the driver version 2.1.5 or revert to driver version 2.1.3.

Impact

A SQL injection is possible in the Amazon Redshift Python Connector, version 2.1.4, when leveraging metadata APIs to retrieve information about database schemas, tables, or columns.

Impacted versions: Amazon Redshift Python Connector version 2.1.4.

Patches

The issue described above has been addressed in the Amazon Redshift Python Connector, version 2.1.5.

The patch implemented in this version ensures that every metadata command input is sent to the Redshift server as part of a parameterized query, using either QUOTE_IDENT(string) or QUOTE_LITERAL(string). After processing all the inputs into quoted identifiers or literals, the metadata command is composed using these inputs and then executed on the server.

Workarounds

Use the previous version of the Amazon Redshift Python Connector, version 2.1.3.
