Description

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data within the extension script @substitutions@, which uses @extowner@, @extschema@, or @extschema:...@ inside a quoting construct. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.
