Wfsection 1.07 vulnerabilities

[kreon <kre0n () mail ru>]

Program: wfsections
Verion: 1.07
Bug Type: SQL Injection
Bug Discription:
=================================
In file class/wfsfiles.php, we can see this function:
//START
function getAllbyArticle($articleid) {
        $db =& Database::getInstance();
        $table = $db->prefix("wfs_files");
        $ret = array();
        $sql = "SELECT * FROM ".$table." WHERE articleid=".$articleid."";
        $result = $db->query($sql);
        while( $myrow = $db->fetchArray($result) ){
                $ret[] = new WfsFiles($myrow);
        }
        return $ret;
}
//END
Param $articleid inserts into sql-query without any checks, so we can
make sql-injection. Example:
http://[path]/[folder[/article.php?articleid=1[SQL Code[like OR 1=1]]
Patch: replace string 
$sql = "SELECT * FROM ".$table." WHERE articleid=".$articleid."";
With string
$sql = "SELECT * FROM ".$table." WHERE
articleid=".intval($articleid)."";
