Introduction:
=============
The Barracuda Control Center is a comprehensive cloud-based service that enables administrators to
monitor and configure multiple Barracuda Networks products from a single console. With the
Barracuda Control Center, you can check the health of all connected devices, run reports that are
generated by gathering data from all the devices, and assign roles with varied permissions to different
types of users. The powerful Web interface of the Barracuda Control Center provides for convenient 
configuration and management of multiple Barracuda Networks device settings, while also providing a view 
of each device Web interface for individual configuration or reporting. No need to install software or 
deploy hardware. Key statistics can be viewed by device type at a glance on the Status page of the Web 
interface with the ability to drill down for more detail into the individual Web interface for each connected device.

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


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


Details:
========
1.1
A persistent Input Validation Vulnerability is detected on Barracudas Cloud Control Center Application v3.0.04.015. 
Local low privileged user account can implement/inject malicious script code to manipulate modules via persistent context 
requests. When exploited by an authenticated user, the identified vulnerabilities can result in information disclosure via error, 
session hijacking, access to cloud/intranet available servers/services, manipulated persistent content on user/mail listing requests.

Vulnerable Module(s): 
                [+] User Management - Access Name/Mail Listing

1.2
Multiple client side cross site scripting vulnerabilities are detected on Barracudas Cloude Control Center Application v3.0.04.015. 
The vulnerability allows an attacker (remote) to hijack customer/moderator/admin sessions with medium required user inter 
action. Successful exploitation can result in account steal or client side context manipulation when processing cloud based
application module requests.

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

Risk:
=====
1.1
The security risk of the persistent input validation vulnerability is estimated as medium(+).

1.2
The security risk of the non-persistent (client side) cross site scripting vulnerabilities are estimated as low(+).
