-- between common and vulnerabilities removed

Changed: *SQL injection* is a common exploit in which an attacker alters Web page
parameters (such as ``GET``/``POST`` data or URLs) to insert arbitrary SQL
snippets that a naive Web application executes in its database directly. It's
probably the most dangerous -- and, unfortunately, one of the most common -- vulnerabilities out there.
