Improper Access Control
CWE-284
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
We track 3,726 vulnerabilities of this type. 100% are rated high or critical, and the average CVSS score is 8.3. 36 have been exploited in real attacks.
How this weakness is prevented
- Architecture and Design Operation: Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- 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.
