A vulnerability in the CLI of the Cisco Prime Network Gateway could allow an authenticated, local attacker to retrieve system process information, which could lead to the disclosure of confidential information. The vulnerability is due to a lack of input and validation checking mechanisms in the system. An attacker could exploit this vulnerability by issuing specific, known commands after authenticating locally to the system via the CLI. A successful exploit could allow the attacker to view confidential information that should only be visible to authenticated users. There are no workarounds that address this vulnerability.
