The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity
Low
AC
The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required
None
PR
The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
Scope
Unchanged
S
An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality
High
C
There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity
High
I
There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability
High
A
There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

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.

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.

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.
