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.
