Securing Password Rest Bug in Joomla CMS prior version 1.5.6

There is a password reset forgery in earlier versions than 1.5.6 of joomla, even in 1.5.5. You can fix this either by updating to 1.5.6 version of add following patch.

According to Joomla " A flaw in the reset token validation mechanism allows for non-validating tokens to be forged. This will allow an unauthenticated, unauthorized user to reset the password of the first enabled user (lowest id). Typically, this is an administrator user. Note, that changing the first users username may lessen the impact of this exploit (since the person who changed the password does not know the login associated with the new password). However, the only way to completely rectify the issue is to upgrade to 1.5.6 (or patch the /components/com_user/models/reset.php file). "

Add following(in bold, italic) in the File: /var/www/oweraweb/test/components/com_user/models/reset.php 

in function confirmReset($token),after global $mainframe; line 113.

        function confirmReset($token)
        {
                global $mainframe;

                      // Patch to disable passwd resetbug of  first user (admini$
                        if(strlen($token) != 32) {
                        $this->setError(JText::_('INVALID_TOKEN'));
                        return false;
                        }
