* 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 affiché 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
