Mitigating Controls (NIST 800-53 r5) AI

AC-12 Session Termination good match
prevent

Directly requires automatic session termination on defined events such as browser closure, eliminating the exact CWE-613 flaw that permits impersonation.

AC-3 Access Enforcement partial match
prevent

Enforces access decisions on every request using current session state, so an unexpired post-closure session would be rejected if the control validates termination status.

IA-11 Re-authentication partial match
prevent

Forces re-authentication after events like browser closure, preventing continued use of the stale session that the CVE leaves valid.

Mitigating Controls (NIST CSF 2.0) AI

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

PR.AA-01 mostly match
prevents

Credential lifecycle management directly includes enforcing session expiration to prevent reuse.

PR.AA-05 mostly match
prevents

Authorization policy enforcement and review covers terminating stale sessions to limit access scope.

PR.AA-03 partial match
prevents

Authentication mechanisms can incorporate session timeout checks but do not inherently address expiration policy.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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.

A.8.5 Secure authentication none match
none

Automatic termination of inactive sessions and limits on connection duration shrink the window during which a hijacked or unattended authenticated session can be exploited.
