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-200Exposure of Sensitive Information to an Unauthorized Actor10,260Wireless link protection (encryption, directional transmission, etc.) directly prevents unauthorized actors from observing transmitted data.
CWE-287Improper Authentication4,758Requires authentication mechanisms on the wireless link, making improper authentication weaknesses harder to exploit.
CWE-319Cleartext Transmission of Sensitive Information1,051Mandates cryptographic protection of the wireless medium, eliminating cleartext transmission of sensitive information over the air.
CWE-290Authentication Bypass by Spoofing645Signal-parameter protections (e.g., cryptographic authentication, anti-spoofing) directly counter spoofing-based authentication bypass.
CWE-294Authentication Bypass by Capture-replay267Wireless link protections commonly incorporate replay protection, reducing the exploitability of capture-replay weaknesses.
CWE-923Improper Restriction of Communication Channel to Intended Endpoints57Enforces that the wireless communication channel is usable only by intended endpoints, addressing improper channel restriction.
CWE-300Channel Accessible by Non-Endpoint53The control restricts an inherently broadcast wireless channel to only intended endpoints, mitigating accessibility by non-endpoints.
