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-862Missing Authorization11,800+Mandating authorization for changes prevents missing authorization checks on critical modification functions.
CWE-284Improper Access Control8,100+Enforcing physical and logical access restrictions for system changes directly prevents unauthorized actors from modifying the system.
CWE-863Incorrect Authorization4,800+The control requires correct implementation of authorization specifically tied to change operations.
CWE-269Improper Privilege Management4,000+Restricting who can perform changes helps ensure privileges are managed properly rather than assigned broadly.
CWE-732Incorrect Permission Assignment for Critical Resource2,000+Defining and enforcing access restrictions ensures correct permission assignments on resources that support changes.
CWE-285Improper Authorization1,700+Requiring definition, approval, and enforcement of access rules for changes addresses improper authorization of modifications.
CWE-250Execution with Unnecessary Privileges300+Limiting change access to only approved entities reduces the risk of unnecessary privileges being available for modifications.
CWE-15External Control of System or Configuration Setting92Restricting changes to system and configuration settings prevents external entities from controlling those settings without approval.
