Barracuda, a company known for its email and network security solutions, warned customers today that some of their Email Security Gateway appliances were breached last week by targeting a now-patched zero-day vulnerability.
While the flaw was patched over the weekend, Barracuda warned on Tuesday that some of its customers' ESG appliances were compromised by exploiting the now-patched security bug.
"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."
"If a customer has not received notice from us via the ESG user interface, we have no reason to believe their environment has been impacted at this time and there are no actions for the customer to take," Barracuda told BleepingComputer.
A spokesperson for Barracuda didn't reply to a subsequent email asking for more details regarding the number of affected customers or if their data was impacted after their ESG appliances were breached.
Today, Barracuda also addressed a login issue affecting Email Gateway Defense appliances and a buggy spam scoring rule that led to customer emails being blocked incorrectly.
