The Cisco Application Control Engine (ACE) software installed on the remote Cisco ACE 4710 device is an A5 version prior to A5(3.0). It is, therefore, affected by a remote command injection vulnerability in the device manager GUI due to improper validation of user-supplied input in HTTP POST requests. An authenticated, remote attacker can exploit this to bypass the role-based access control (RBAC) restrictions and execute CLI commands with ‘admin’ privileges.
