Official description

Vasion Print (formerly PrinterLogic) Virtual Appliance Host and Application (VA and SaaS deployments) contains multiple Docker containers that run primary application processes (for example PHP workers, Node.js servers and custom binaries) as the root user. This increases the blast radius of a container compromise and enables lateral movement and host compromise when a container is breached.

The underlying weakness: Improper Privilege Management

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

How developers prevent this class of flaw

  • Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
  • Follow the principle of least privilege when assigning access rights to entities in a software system.
  • Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
