<![CDATA[🔴 Critical: Cisco patches Secure Email Gateway zero-day exploited in attacks]]>Cisco has issued a warning about a critical zero-day vulnerability in its Secure Email Gateway product, confirming that threat actors have already exploited the flaw in active attacks. The vulnerability allows attackers to execute commands as root, making it a serious risk for organizations running the affected software.

Administrators should treat this as an urgent patching priority, especially since exploitation has been observed in the wild. Cisco has released fixes, and applying them as soon as possible is the recommended course of action.

Apply the latest patches from Cisco for Secure Email Gateway
Monitor for signs of compromise on internet-facing email gateway appliances
