Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-37 Out-of-band Channels
addresses: CWE-523

Using a distinct channel for credential transmission prevents unprotected transport over the application's normal communication path.

SC-8 Transmission Confidentiality and Integrity
addresses: CWE-523

Requiring protected transport for credentials directly mitigates unprotected credential transmission over networks.

SC-9 Transmission Confidentiality
addresses: CWE-523

Prevents unprotected transport of credentials by mandating confidentiality mechanisms such as TLS for all sensitive data flows.
