BARRACUDA EMAIL SECURITY GATEWAY APPLIANCE (ESG) VULNERABILITY

WE ARE COMMITTED TO

SECURING YOUR DATA




BARRACUDA EMAIL SECURITY GATEWAY APPLIANCE (ESG) VULNERABILITY

 


MAY 23RD, 2023:

Barracuda identified a vulnerability (CVE-2023-2868) in our Email Security
Gateway appliance (ESG) on May 19, 2023. A security patch to eliminate the
vulnerability was applied to all ESG appliances worldwide on Saturday, May 20,
2023. The vulnerability existed in a module which initially screens the
attachments of incoming emails. No other Barracuda products, including our SaaS
email security services, were subject to this vulnerability.

We took immediate steps to investigate this vulnerability. Based on our
investigation to date, we’ve identified that the vulnerability resulted in
unauthorized access to a subset of email gateway appliances. As part of our
containment strategy, all ESG appliances have received a second patch on May 21,
2023. Users whose appliances we believe were impacted have been notified via the
ESG user interface of actions to take. Barracuda has also reached out to these
specific customers.

We will continue actively monitoring this situation, and we will be transparent
in sharing details on what actions we are taking. Information gathering is
ongoing as part of the investigation. We want to ensure we only share validated
information with actionable steps for you to take. As we have information to
share, we will provide updates via this product status page
(https://status.barracuda.com) and direct outreach to impacted customers.
Updates are also located on Barracuda’s Trust Center
(https://www.barracuda.com/company/legal).

Barracuda’s investigation was limited to the ESG product, and not the customer’s
specific environment. Therefore, impacted customers should review their
environments and determine any additional actions they want to take.

Your trust is important to us. We thank you for your understanding and support
as we work through this issue and sincerely apologize for any inconvenience it
may cause. If you have any questions, please reach out to support@barracuda.com.
