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.
