Weakness (CWE)

CWE-272: Least Privilege Violation

Base Incomplete

The elevated privilege level required to perform operations such as chroot() should be dropped immediately after the operation is performed.

How to prevent it (3 mitigations)

  1. Architecture and Design, Operation

    Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.

  2. Architecture and Design

    Follow the principle of least privilege when assigning access rights to entities in a software system.

  3. Architecture and Design

    Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.

    Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
