Weaknesses this control addresses (6)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-287 | Improper Authentication | 5,600+ | Mandates unique identification and authentication of non-organizational users, directly mitigating improper authentication. |
CWE-306 | Missing Authentication for Critical Function | 3,900+ | Requires authentication for non-organizational users, preventing access to critical functions without proper identification and authentication. |
CWE-290 | Authentication Bypass by Spoofing | 800+ | Unique identification of non-organizational users reduces the feasibility of authentication bypass by spoofing. |
CWE-288 | Authentication Bypass Using an Alternate Path or Channel | 700+ | Enforces authentication for non-organizational users, making it harder to bypass via alternate paths or channels. |
CWE-304 | Missing Critical Step in Authentication | 48 | Ensures the authentication process is followed for non-organizational users, avoiding missing critical steps. |
CWE-302 | Authentication Bypass by Assumed-Immutable Data | 45 | Proper authentication for non-organizational users counters bypasses relying on assumed-immutable data. |
