Medium


Details:
========
A non-persistent cross site scripting vulnerability is detected on the NexorONE 
Online Banking Software. 
Successful exploitation of the vulnerability allows an attacker to hijack 
user/mod/admin sessions of the portal.

Vulnerable file(s):
                                                        [+] login.php

Vulnerable Param(s):
                                                        [+] ?visitor_language=
                                                        [+] ?message=

Proof of Concept:
=================
The vulnerabilities can be exploited by remote attackers with required user 
inter action. For demonstration or reproduce ...
