CVE-2023-46249

Session content review can reveal authentication bypasses or failures in session establishment.

Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.

Documented IA policy and procedures require proper authentication mechanisms to be defined and followed, reducing improper authentication.

Requires adaptive authentication under specific conditions, directly strengthening authentication mechanisms against improper or insufficient authentication.

Identity providers centralize and enforce authentication mechanisms, reducing improper authentication.

Requires unique identification and authentication of organizational users, directly preventing improper authentication.

Enforces unique device identification and authentication before any connection is established, directly mitigating improper authentication weaknesses.

Directly requires implementation of compliant authentication mechanisms to cryptographic modules, preventing improper authentication.

Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.

Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.

Defining and enforcing authorizations assumes prior authentication and therefore only partially mitigates the absence of authentication.

Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.

Mandating segregated approval and oversight for non-human identities reduces the chance that weak or orphaned credentials can be exploited for unauthorized authentication.

A.5.17 directly mandates generation of non-guessable unique secrets, secure transmission, immediate change of defaults/temporary creds, strong password enforcement, no-reuse, and compromise response, which stops most improper-authentication exploits at source; the bounded remainder is non-password authentication methods and sufficiency-of-proof cases (e.g. IA-2/IA-5 enhancements) left to other controls.

Mandating authentication requirements for critical functions at the requirements-gathering stage ensures that essential operations are not left unprotected by missing login or verification mechanisms.
