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-862 | Missing Authorization | 10,200+ | Field maintenance is a critical function; the control supplies the missing authorization step by limiting it to specified entities. |
CWE-284 | Improper Access Control | 6,900+ | Restricting field maintenance directly enforces access control over who can interact with or modify the system in uncontrolled environments. |
CWE-863 | Incorrect Authorization | 3,900+ | By defining exactly who may perform field maintenance, the control corrects potential authorization errors for this activity. |
CWE-269 | Improper Privilege Management | 3,400+ | Maintenance typically requires elevated privileges; limiting field maintenance helps enforce proper privilege management. |
CWE-285 | Improper Authorization | 1,500+ | The control requires explicit authorization for maintenance activities, preventing unauthorized parties from performing them. |
CWE-1263 | Improper Physical Access Control | 13 | Field maintenance requires physical or on-site access, and restricting it mitigates improper physical access control. |
