Barracuda Networks Spam Firewall Multiple Vulnerabilities

Vulnerability Assessment Summary
Tries to authenticate to Barracuda Networks Spam Firewall

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote web server is affected by multiple vulnerabilities.

Description :

The remote host appears to be a Barracuda Spam Firewall network
appliance, which protects mail servers from spam, viruses, and the
like.

The firmware version of the Barracuda Spam Firewall on the remote
device fails to filter input to the 'file' parameter of the
'/cgi-bin/preview_email.cgi' script before using it to read files.
Using specially crafted strings, an unauthenticated attacker can
leverage this flaw to read arbitrary files and even execute arbitrary
commands on the remote host. While the web server executes as the
user 'nobody', it is possible to access several system commands
through the use of 'sudo' and thereby gain root rights.

In addition, the application contains hardcoded passwords for the
'admin' and 'guest' users.

Solution :

We are unaware of a public statement from the vendor regarding a fix,
but upgrading to firmware version 3.3.0.54 or later reportedly
addresses the issues.
