Open Mail Relay Vulnerability in Barracuda Spam Firewall by Barracuda Networks

CVE-2005-0431

What is CVE-2005-0431?

The Barracuda Spam Firewall versions up to 3.1.10 allow users of whitelisted domains to leverage the firewall as an open mail relay. This means that members of these domains can send unsolicited emails through the firewall, potentially flooding networks with spam. The vulnerability stems from a lack of restrictions on outgoing mail processes. Organizations utilizing these firewall versions should review their configurations to mitigate the risks associated with unauthorized email relay.
