A vulnerability in the configuration archive functionality of Cisco DNA Center could allow any privilege-level authenticated, remote attacker to obtain the full unmasked running configuration of managed devices. The vulnerability is due to the configuration archives files being stored in clear text, which can be retrieved by various API calls. An attacker could exploit this vulnerability by authenticating to the device and executing a series of API calls. A successful exploit could allow the attacker to retrieve the full unmasked running configurations of managed devices.
