CVE-2023-20256

Reveals spoofed logon attempts through unexpected previous logon timestamps upon legitimate login.

Training specifically addresses recognizing spoofed communications and phishing that enable authentication bypass.

Requiring verifiable identity evidence at appropriate assurance levels makes it substantially harder for attackers to successfully spoof or impersonate users to obtain accounts.

Unique device authentication makes successful spoofing of device identity substantially more difficult to achieve.

Unique identification of non-organizational users reduces the feasibility of authentication bypass by spoofing.

Unique identification and authentication of services before communications makes spoofing of service identities substantially harder.

Isolated trusted path ensures the user interacts only with genuine system components, preventing spoofing of authentication interfaces or prompts.

Directly counters DNS response spoofing by requiring cryptographic origin authentication artifacts from the authoritative source.

Proofing and binding identities reduces spoofing opportunities during enrollment but does not address runtime authentication implementation flaws.

Requiring authentication of users/services/hardware directly counters spoofing-based bypass when strong methods are used.

Protecting, conveying, and verifying identity assertions specifically prevents the spoofing that enables authentication bypass.

A.5.15 only requires that an access control policy and requirements be defined and communicated; it does not itself implement, enforce or configure any authentication scheme that would stop spoofing attacks from bypassing authentication, so the weakness remains fully exploitable.

A.5.16 manages the lifecycle, uniqueness, and accountability of identities; it does not implement or strengthen authentication schemes against spoofing, so the CWE-290 exploit remains possible even when identities are correctly provisioned and tracked.

Authentication information management directly addresses credential handling that prevents spoofing.

A.5.18 governs the provisioning, review, and revocation of already-granted access rights to authenticated identities; it has no bearing on whether an authentication scheme can be spoofed or bypassed before any rights are assigned.
