1) Description:


Error occured in cal_event.php:

$dquery = "delete from ".$EVENTS_TB." where id='$id'";

Error occured in cal_popup.php:

$id = $_GET['id'];

2) Proof of concept:

http://example/[c_path]/cal_event.php?id=[SQL_QUERY]
http://example/[c_path]/cal_popup.php?id=[SQL_QUERY]

3) Solution:

on cal_event.php sanitized $id variable,
on cal_popup.php don't use $_GET['id'] to assign a value.
