VPN clients are commonly found on laptops for remote office workers, This is a local priv esc on all Aviatrix VPN Clients. As it is local it would need either a malicious user or an attacker with User level access looking to escalate.

When the VPN client starts it creates a locally running Web service. This service is capable of running commands in the context of the service, which runs as Root / Admin level permissions.

The service uses a set of certificates to authenticate the web service, however these certificates are included in a compiled python executable, it is it trivial to recover these certificated and therefore execute commands to gain elevated privileges.
