* 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
