Interspire or Big-Commerce how to bypass admin login

Hello friends today i am sharing with you an interesting hack for Interspire Shopping Cart or BigCommerce admin login hack which i got to tasked some time ago :

Note : In this hack you must have at-least valid user name this hack only bypass wrong password

Follow below instructions :
1) login to FTP
2) Navigate to admin/includes/classes
3) Locate the class class.auth.php
4) And around line number 235 you will find the this code
[php]if ($autoLogin || $userManager->verifyPassword($uid, $loginPass) == true) [/php]

Replace this with this one do not forget to save the original code

[php] if (1) [/php]

And try login with valid username and any password.

Hope this could help someone :-)
