A vulnerability in the remote support functionality of Cisco WSAv, Cisco ESAv, and Cisco SMAv Software could allow an unauthenticated, remote attacker to connect to the affected system with the privileges of the root user.
The vulnerability is due to the presence of a default authorized SSH key that is shared across all the installations of WSAv, ESAv, and SMAv.
An attacker could exploit this vulnerability by obtaining the SSH private key and using it to connect to any WSAv, ESAv, or SMAv. An exploit could allow the attacker to access the system with the privileges of the root user.
