Weaknesses this control addresses (8)AI-assisted
CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.
| CWE | Name | CVEs | Why this control addresses it |
|---|---|---|---|
CWE-862 | Missing Authorization | 10,200+ | The control mandates authorization prior to allowing use of designated components, eliminating missing authorization paths. |
CWE-284 | Improper Access Control | 6,900+ | Requiring authorization, monitoring, and control of component use directly enforces access control decisions on system resources. |
CWE-863 | Incorrect Authorization | 3,900+ | Ongoing monitoring and control of component usage detects and stops incorrect authorization decisions at runtime. |
CWE-269 | Improper Privilege Management | 3,400+ | Usage restrictions and implementation guidelines limit how privileges may be exercised with the specified components. |
CWE-306 | Missing Authentication for Critical Function | 3,300+ | Requiring authorization for listed components ensures authentication occurs before critical functions are invoked. |
CWE-732 | Incorrect Permission Assignment for Critical Resource | 1,900+ | Establishing usage restrictions and guidelines directly addresses assignment of appropriate permissions to critical components. |
CWE-285 | Improper Authorization | 1,500+ | Explicit authorization step before component use prevents actions that bypass intended authorization checks. |
CWE-250 | Execution with Unnecessary Privileges | 300+ | Authorizing only necessary component uses reduces the chance of processes running with extraneous privileges. |
