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.
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.
Identity providers centralize and enforce authentication mechanisms, reducing improper authentication.
Enforces correct authorization checks during the identifier assignment process.
Personnel screening, identity verification, and access-agreement requirements support reliable authentication and reduce authentication bypass opportunities.
Decoy authentication surfaces detect bypass attempts and deflect real credential attacks through observable malicious interactions.
Periodic review and update of procedures reduces incorrect authorization implementations over time.
Supervision identifies cases where authorization logic incorrectly permits unauthorized actions.
