Official description

A vulnerability in the web-based management interface of Cisco AsyncOS software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to access sensitive information on an affected device. The vulnerability is due to insufficient validation of requests that are sent to the web-based management interface.

There is a workaround that addresses this vulnerability.
