Check if you are vulnerable description
Cisco Secure Email Gateway deployments using the AMP file reputation service are affected by an attachment-handling flaw. A remote unauthenticated attacker may be able to send a malicious attachment that writes files to the appliance and can lead to commands running as root.
mitigation
Disable the AMP file reputation service where operationally feasible until vendor guidance is applied. No fixed version is recorded; monitor Cisco's advisory and update affected appliances when a corrected release is provided.
