sqlmap

sqlmap is an open source penetration testing tool that automates the process of
detecting and exploiting SQL injection flaws and taking over of database
servers. It comes with a powerful detection engine, many niche features for the
ultimate penetration tester and a broad range of switches lasting from database
fingerprinting, over data fetching from the database, to accessing the
underlying file system and executing commands on the operating system via
out-of-band connections.
