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 termination after a set interval shortens the usable lifetime of a fixed session identifier, making successful exploitation of session fixation more difficult.
Re-authentication typically forces issuance of a new session, limiting the window for exploitation of a previously fixed session identifier.
Enforces proper session ID generation and binding, preventing fixation of a known session token.
