SQL injection is a technique that exploits a security
vulnerability occurring in the database layer of an
application. The vulnerability is present when user input
is either incorrectly filtered for string literal escape
characters embedded in SQL statements or user input is not
strongly typed and thereby unexpectedly executed. It is in
fact an instance of a more general class of vulnerabilities
that can occur whenever one programming or scripting
language is embedded inside another.
