SQL Injection in elide-datastore-aggregation

Impact

When leveraging the following together:

• Elide Aggregation Data Store for Analytic Queries
• Parameterized Columns (A column that requires a client provided parameter)
• A parameterized column of type TEXT

There is the potential for a hacker to provide a carefully crafted query that would bypass server side authorization filters through SQL injection. A recent patch to Elide 6.1.2 allowed the ‘-’ character to be included in parameterized TEXT columns. This character can be interpreted as SQL comments (‘–’) and allow the attacker to remove the WHERE clause from the generated query and bypass authorization filters.

Patches

A fix is provided in Elide 6.1.4.

Workarounds

The vulnerability only exists for parameterized columns of type TEXT and only for analytic queries (CRUD is not impacted). Workarounds include leveraging a different type of parameterized column (TIME, MONEY, etc) or not leveraging parameterized columns.
