Zero-day exploited to breach Barracuda email gateways

BleepingComputer reports that some Barracuda Email Security Gateway instances have been compromised in attacks exploiting a zero-day vulnerability, which has already been patched in security updates issued over the weekend. No other Barracuda products have been impacted by the security flaw, according to Barracuda Networks, which has already informed users whose appliances may have been breached. Organizations using Barracuda ESG have been urged to conduct a review of their environments to ensure the safety of other network devices. "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," said Barracuda. Meanwhile, fixes have also been issued by Barracuda for a login issue and a faulty spam scoring logic in its Email Gateway Defense appliances.
