Product & Service Introduction:
===============================
We are pleased to announce the General Availability of the Astaro Command Center Version 2.0. This new version introduces the major new ability 
to configure and manage IPSEC tunnels entirely within ACC itself. By providing a centralized location from which to work with and deploy VPN 
tunnels between Astaro installations, administrators can save management time and automate many of the tasks involved in successfully linking 
sites together with encrypted links. The Astaro Command Center is an entirely free product that allows you to centrally monitor and maintain 
multiple Astaro installations & devices. If you currently are responsible for more than one Astaro Gateway product, ACC is designed for you! 
Read on for more information. Starting with this release, it is now possible to setup site-to-site VPN tunnels with an amazing degree of ease 
from within Astaro Command Center itself. Simply indicate the devices to be joined together via VPN, select a few options, and the rest is 
automated with no need to login to each individual WebAdmin for the configuration. ACC is presented in the same administrative style as our AxG 
Version 7 WebAdmin, so that if you are new to ACC you will have no trouble getting started within a familiar looking environment.

Affected Product(s):
====================

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


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


Technical Details & Description:
================================
Multiple  persistent input validation vulnerabilities are detected in Astaro Command Center v2.x.
The bugs allows an local privileged attackers to implement/inject malicious script code on the application-side (persistent).
Successful exploitation of the vulnerability can lead to session hijacking (manager/admin) or stable (persistent) 
context manipulation. Exploitation requires user inter action & minimum restricted access to the panel.

Vulnerable Module(s):
						[+] Configuration - Networks Definition
						[+] Deploy Function
						[+] Summary
						[+] VPN Information/ Configuration VPN Details
						[+] Management - Organizational Units


Proof of Concept (PoC):
=======================
This vulnerabilities can be exploited local(persistent) by low privileged user accounts or 
by user inter-action (remote) via request force  ...

Solution - Fix & Patch:
=======================
Restrict the input fields by a specific char filter as mask like [a-z][A-Z][0-9]  ...
Implement a own secure exception-handling to prevent against persistent script-code injects.

To patch the issues upgrade to astaro command center (now sophos 2012) version 3 and disallow the posts of low privileged user accounts.


Security Risk:
==============
The security risk of the persistent vulnerabilities are estimated as medium(+) because they are all located in main areas of the application.
