A vulnerability in the CLI of Cisco AsyncOS for Cisco Email Security Appliance (ESA) and Cisco AsyncOS for Cisco Content Security Management Appliance (SMA) 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.
Information written to log files can be of a sensitive nature and give valuable guidance to an attacker or expose sensitive user information.

While logging all information may be helpful during development stages, it is important that logging levels be set appropriately before a product ships so that sensitive user data and system information are not accidentally exposed to potential attackers. Different log files may be produced and stored for:
