Daily Cyber News: Active attacks put Cisco email security gateways at root-level risk

A system designed to stop malicious email can now become an attacker’s privileged foothold. Attackers have exploited a weakness affecting on-premises Cisco Secure Email Gateway appliances running AsyncOS 16.5, 16.0, and 15.5 and earlier. A crafted email can trigger the issue without any user interaction and lead to command execution with root privileges.

Key context: Root access could allow an attacker to change security policies, hide evidence, or use the gateway to reach other systems.
