SQL injection
is a
code injection
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 an instance of a more general class of vulnerabilities that can occur whenever one programming or scripting language is embedded inside another. SQL injection attacks are also known as SQL insertion attacks.
