"According to its self-reported version, the host is affected by a vulnerability in the CLI of Cisco AsyncOS for Cisco
Email Security Appliance (ESA) that could allow an authenticated, remote attacker to access sensitive information on an
affected device. The vulnerability is due to excessive verbosity in certain log subscriptions. An attacker could exploit
this vulnerability by accessing specific log files on an affected device. A successful exploit could allow the attacker 
to obtain sensitive log data, which may include user credentials. To exploit this vulnerability, the attacker would need
to have valid credentials at the operator level or higher on the affected device.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.");
