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.

AC-12 Session Termination
addresses: CWE-384

Session termination after a set interval shortens the usable lifetime of a fixed session identifier, making successful exploitation of session fixation more difficult.

IA-11 Re-authentication
addresses: CWE-384

Re-authentication typically forces issuance of a new session, limiting the window for exploitation of a previously fixed session identifier.

SC-23 Session Authenticity
addresses: CWE-384

Enforces proper session ID generation and binding, preventing fixation of a known session token.

PR.AA-01 partial match
blocks

Managing identities and credentials includes handling session identifiers as temporary credentials that must be invalidated on re-authentication.

PR.AA-03 partial match
blocks

Proper authentication processes must invalidate prior session identifiers to prevent fixation attacks.

PR.AA-04 partial match
blocks

Protecting and verifying identity assertions encompasses secure handling and regeneration of session tokens.

PR.PS-01 partial match
blocks

Configuration baselines can enforce session regeneration and timeout settings that block fixation.
