Barracuda Spam Firewalls from version 3.3.01.001 to 3.3.02.053 have default login credentials that can not be modified by an administrator.
Barracuda Spam Firewall appliances provide ingress and egress spam filtering for local area networks. An administrator will typically log into the device by supplying credentials to a secure web-interface.
Barracuda Spam Firewalls version 3.3.01.001 to 3.3.02.053 have a guest account with a fixed username and password. This account can log in to the web interface and can not be restricted by the system’s built-in access control lists.
A remote, unauthenticated attacker can view system configuration files or other sensitive data.
Upgrade
Barracuda has published updates that address this issue. Refer to the systems affected portion of this document for more details.
Restrict Access
Do not allow access to the web interface of the Barracuda Spam Firewall from untrusted networks.
Block Access to the Web Interface
Blocking access to ports 443/tcp
and 8080/tcp
will prevent any user from logging into the web-interface, but will not interfere with the spam filtering functions of the firewall.

Updated: August 24, 2006
Affected
On August 3, 2006, system settings were delivered to all Barracuda Spam Firewalls in the field via Energize Updates to disable the underlying mechanisms behind these vulnerabilities. As such, no Barracuda Spam Firewalls with current Energize Updates subscriptions should be affected by these vulnerabilities.
As part of the test rollout, these settings were initially delivered with the upgrade to early release firmware 3.4.05.017 on July 14, 2006. These settings were later successfully delivered with the upgrade to generally available firmware 3.3.03.055 on July 18, 2006. While it is generally recommended that customers upgrade to the latest release, these upgrades are no longer necessary for protection against these specific vulnerabilities.
To avoid future vulnerabilities, Barracuda Networks recommends that customers restrict unnecessary external Web access to their Barracuda Spam Firewalls.
Fix:
For firmware version 3.3.x and earlier: upgrade to firmware version 3.3.03.055
For firmware version 3.4.x: upgrade to firmware version 3.4.05.017
