Weaknesses this control addresses (4)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-319 | Cleartext Transmission of Sensitive Information | 1,000+ | Directly prevents cleartext transmission of sensitive information by requiring encryption or equivalent confidentiality protections during transit. |
CWE-598 | Use of HTTP Request With Sensitive Query String | 91 | Protects sensitive data placed in query strings from interception in transit when confidentiality controls like HTTPS are enforced. |
CWE-300 | Channel Accessible by Non-Endpoint | 55 | Renders the transmission channel inaccessible to non-endpoint eavesdroppers through encryption, eliminating the weakness class. |
CWE-523 | Unprotected Transport of Credentials | 25 | Prevents unprotected transport of credentials by mandating confidentiality mechanisms such as TLS for all sensitive data flows. |
