CVE-2024-25628Network attack vector

Persistent admin access via unterminated sessions

Published Feb 16, 2024 · Updated Aug 6, 2024

Insufficient session expiration in alf.io before 2.0-M4-2402 allows remote authenticated users to retain admin-area access. The application does not terminate existing authenticated sessions when the associated administrator account is invalidated or deleted. Exploitation requires a previously authenticated administrator session, and the consequence is continued access to the admin area after account revocation.
