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+ | Mandating authorization for changes prevents missing authorization checks on critical modification functions. |
CWE-284 | Improper Access Control | 6,900+ | Enforcing physical and logical access restrictions for system changes directly prevents unauthorized actors from modifying the system. |
CWE-863 | Incorrect Authorization | 3,900+ | The control requires correct implementation of authorization specifically tied to change operations. |
CWE-269 | Improper Privilege Management | 3,400+ | Restricting who can perform changes helps ensure privileges are managed properly rather than assigned broadly. |
CWE-732 | Incorrect Permission Assignment for Critical Resource | 1,900+ | Defining and enforcing access restrictions ensures correct permission assignments on resources that support changes. |
CWE-285 | Improper Authorization | 1,500+ | Requiring definition, approval, and enforcement of access rules for changes addresses improper authorization of modifications. |
CWE-250 | Execution with Unnecessary Privileges | 300+ | Limiting change access to only approved entities reduces the risk of unnecessary privileges being available for modifications. |
CWE-15 | External Control of System or Configuration Setting | 76 | Restricting changes to system and configuration settings prevents external entities from controlling those settings without approval. |
