FG-Injector is a tool that leverages the pentesters work by facilitating the exploitation of SQL Injection vulnerabilities. It includes a a powerful proxy feature for intercepting and modifying HTTP requests, a network spy module to allow the analyst view HTTP requests and their corresponding responses and an inference engine for automating SQL injection exploitation. The Inference Engine Module of the FG-Injector Framework automates the generation and injection of SQL statements needed for exploitation of a Blind SQL Injection. This module will work also for regular injections using the same method. It can produce blind injections on web/app servers using MS SQL Server, MySQL, and PostgresSql DBMSs.
