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.

addresses: CWE-287 CWE-1390

Detects unauthorized successful logons resulting from improper authentication implementations.

addresses: CWE-287 CWE-1390

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

addresses: CWE-287 CWE-1390

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

addresses: CWE-287 CWE-1390

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

addresses: CWE-287 CWE-1390

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

addresses: CWE-287

Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.

addresses: CWE-287

Security awareness training instructs users on secure authentication practices and avoiding credential compromise.

addresses: CWE-287

Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

blocks

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

blocks

A.5.17 directly mandates non-guessable unique secrets, identity verification before issuance, secure transmission, immediate default changes, strong password enforcement, no reuse, and protected storage/transmission, which stops exploitation of most insufficient-proof cases in CWE-1390; the bounded remainder is non-password mechanisms (e.g. biometrics, certificates) or flawed protocol-level proof not covered by these password-centric rules.

blocks

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.

blocks

A.8.26 explicitly requires identifying and addressing authentication-related requirements (including level of trust in identity via 8.5 and 5.17) as part of application development or acquisition, which prevents a slice of CWE-287 but leaves the dominant sufficiency-of-proof aspects (IA-2/IA-5) and many implementation defects untouched.

blocks

A.8.27 mandates security-by-design principles (least privilege, default-deny, never-trust/always-verify, MFA, end-to-end encryption of requests, distrust-external-input, secure session control, and explicit authentication/authorization in every layer), which directly stops most improper-authentication flaws from being exploitable; the bounded remainder is insufficient-proof cases that live only in the strength or correctness of the credential itself (IA-5/IA-2 territory).

blocks

A.8.5 directly mandates choosing sufficiently strong authentication techniques (including MFA, biometrics with fallback, brute-force protection, secure log-on procedures) that prove claimed identity, which stops exploitation of insufficient proof for most but not all cases in CWE-1390 (e.g. residual protocol-level or implementation-specific flaws remain possible).

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-1390, a class-level weakness. Rules are authored against its narrower children: CWE-289, CWE-290, CWE-305, CWE-307, CWE-309.
  • No fine-grained STIG row for CWE-287, a class-level weakness. Rules are authored against its narrower children: CWE-295, CWE-306.
