CWE-653: Improper Isolation or Compartmentalization
What it is
The product does not properly compartmentalize or isolate functionality, processes, or resources that require different privilege levels, rights, or permissions.
- Severity (our rating)
- High
- Likelihood of exploit
- Not rated by MITRE
- Introduced during
- Architecture and Design, Implementation
- Exploited in the wild
- 1 known exploited CVE
In more detail
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.
What an attacker can do
- Gain Privileges or Assume Identity (Access Control)
- Bypass Protection Mechanism (Access Control)
How to prevent it
Architecture and Design
- Break up privileges between different modules, objects, or entities. Minimize the interfaces between modules and require strong access control between them.
How to find it
- Automated Static Analysis - Binary or Bytecode. According to SOAR, the following detection techniques may be useful: Cost effective for partial coverage: Compare binary / bytecode to application permission manifest
- Manual Static Analysis - Source Code. According to SOAR, the following detection techniques may be useful: Highly cost effective: Manual Source Code Review (not inspections) Cost effective for partial coverage: Focused Manual Spotcheck - Focused manual analysis of source
- Architecture or Design Review. According to SOAR, the following detection techniques may be useful: Highly cost effective: Inspection (IEEE 1028 standard) (can apply to requirements, design, source code, etc.) Formal Methods / Correct-By-Construction Cost effective for partial coverage: Attack Modeling
