CVE-2022-3916 – Keycloak: session takeover with oidc offline refreshtokens

https://notcve.org/view.php?id=CVE-2022-3916

A flaw was found in the offline_access scope in Keycloak. This issue would affect users of shared computers more (especially if cookies are not cleared), due to a lack of root session validation, and the reuse of session ids across root and user authentication sessions. This enables an attacker to resolve a user session attached to a previously authenticated user; when utilizing the refresh token, they will be issued a token for the original user. Se encontró una falla en el alcance offline_access en Keycloak. Este problema afectaría más a los usuarios de ordenadores compartidos (especialmente si las cookies no se borran), debido a la falta de validación de la sesión root y a la reutilización de los identificadores de sesión en las sesiones de autenticación de usuario y root. • https://access.redhat.com/errata/RHSA-2022:8961 https://access.redhat.com/errata/RHSA-2022:8962 https://access.redhat.com/errata/RHSA-2022:8963 https://access.redhat.com/errata/RHSA-2022:8964 https://access.redhat.com/errata/RHSA-2022:8965 https://access.redhat.com/errata/RHSA-2023:1043 https://access.redhat.com/errata/RHSA-2023:1044 https://access.redhat.com/errata/RHSA-2023:1045 https://access.redhat.com/errata/RHSA-2023:1047 https://access.redhat.com/errata/RHSA • CWE-384: Session Fixation CWE-613: Insufficient Session Expiration •
