SQL Injection in elide-datastore-aggregation

Vulnerability Description

Elide is a Java library that lets you stand up a GraphQL/JSON-API web service with minimal effort. When leveraging the following together: Elide Aggregation Data Store for Analytic Queries, Parameterized Columns (A column that requires a client provided parameter), and 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. A fix is provided in Elide 6.1.4. 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.
