Description
The product does not properly compartmentalize or isolate functionality, processes, or resources that require different privilege levels, rights, or permissions.
When a weakness occurs in functionality that is accessible by lower-privileged users, then without strong boundaries, an attack might extend the scope of the damage to higher-privileged users.
Modes of Introduction:
– Architecture and Design
Related Weaknesses
CWE-657
CWE-693
Consequences
Access Control: Gain Privileges or Assume Identity, Bypass Protection Mechanism
The exploitation of a weakness in low-privileged areas of the software can be leveraged to reach higher-privileged areas without having to overcome any additional obstacles.
Potential Mitigations
Phase: Architecture and Design
Description:
Break up privileges between different modules, objects, or entities. Minimize the interfaces between modules and require strong access control between them.
