Abstract:
=========
Vulnerability-Lab Team  discovered multiple web vulnerabilities on
Kloxos LxCenter Server CP v6.1.10.


Report-Timeline:
================
2012-02-10:    Public or Non-Public Disclosure


Status:
========
Unpublished


Exploitation-Technique:
=======================
Remote


Severity:
=========
Medium


Details:
========
Multiple persistant input validation vulnerabilities are detected on
Kloxos LxCenter Server CP v6.1.10.
The bug allows remote attacker to implement malicious script code on the
application side (persistent).
Successful exploitation of the vulnerability allows an attacker to
manipulate modules/context (persistent) & can
lead to session hijacking (user/mod/admin).


Vulnerable Module(s):
                            [+] LocalHost {Command Center}
                            [+] Server > Information > Verbose Settings

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

1.1
Localhost {Command Center}

<script> global_need_list = new Array(); </script><script>
global_match_list = new Array(); </script><script>
global_desc_list = new Array(); </script><form onsubmit=``return

<div align=``left`` style=``padding: 10px; background-color: rgb(250,
248, 248); display: block;``> Verbose Description (to Identify)
<font color=``red``><sup>*</sup></font> <br/> 
<input width=``60%`` type=``text`` [PERSISTENT SCRIPT CODE INJECT!]``

Risk:
=====
The security risk of the persistent input validation vulnerabilities is
estimated as medium(+).
