The underlying weakness: Improper Isolation or Compartmentalization

The product does not properly compartmentalize or isolate functionality, processes, or resources that require different privilege levels, rights, or permissions.

How developers prevent this class of flaw

  • Break up privileges between different modules, objects, or entities. Minimize the interfaces between modules and require strong access control between them.
