Vasion Print (formerly PrinterLogic) Virtual Appliance Host and Application (VA/SaaS deployments) contain an undocumented printerlogic user with a hardcoded SSH public key in ~/.ssh/authorized_keys and a sudoers rule granting the printerlogic_ssh group NOPASSWD: ALL. Possession of the matching private key gives an attacker root access to the appliance.
Weakness
The product uses a hard-coded, unchangeable cryptographic key.
