CVE-2023-27377

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.

PR.AA-02 ensures valid enrollment and unique credential binding, which reduces some improper-auth risks at issuance time but leaves runtime claim verification untouched, so each direction only partially addresses the other.

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.

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.

Mandating authentication for network services and critical functions stops attackers from invoking sensitive operations without credentials, closing gaps where authentication is absent for important capabilities.

Security requirements specified early and verified through testing drive the consistent implementation of authentication mechanisms, decreasing the likelihood that authentication steps are omitted or incorrectly applied.
