Recommendation: Plan a near-term fix — a public PoC already exists.

ExaGrid appliances with firmware before 4.8 P26 have a default SSH public key in the authorized_keys file for root, which allows remote attackers to obtain SSH access by leveraging knowledge of a private key from another installation or a firmware image.
