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.

Affected Products:
==================
Barracuda Networks
Product: Cloud Control Center v3.0.04.015


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.

Vulnerable Module(s):
[+] View_Help - Title
[+] Site Listing - Page & OldPage
[+] Audit Log Listing - Name & Content

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

  • Re: How to Pen Test Crazy
    ... I'd like to know how you think that the current practice of seeking vulnerabilities, waiting on patches, or upgrades, testing those patches and upgrades to make sure they don't break anything else, and then starting the cycle over again whenever new vulnerabilities are found to stay a step ahead isn't a cat and mouse game? ... You can either apply the patch and run all the functionality/quality tests to make sure it doesn't break all your 3rd party add-ons until the next time or you can start applying some better ingress/egress filtering which would prevent this problem in all the other interactions via the app to SQL. ... You can react by waiting for a patch or you can find a better way to control that part of your operations. ... But for companies, businesses, governments, and any tech who's supporting home users, the goal should be to get a stable level of security that's usable and not a race against the unknown. ...
