CVE-2024-8995
Full vulnerability record from the local CVENow database.
Description
Unused authorization codes issued to deleted users are not being properly invalidated or removed from the system. This allows for the persistence of these codes, enabling them to be potentially reused. If an attacker possesses both the authorization code and the associated client credentials (client ID and client secret), they can leverage these unused codes to obtain access tokens on behalf of users who have already been deleted. This may lead to unauthorized access to sensitive resources and services, contingent on the scopes originally authorized for the compromised authorization code.

"value": "Los códigos de autorización no utilizados emitidos a usuarios eliminados no están siendo invalidados o eliminados correctamente del sistema. Esto permite la persistencia de estos códigos, lo que permite que sean potencialmente reutilizados.\n\nSi un atacante posee tanto el código de autorización como las credenciales de cliente asociadas (ID de cliente y secreto de cliente), pueden aprovechar estos códigos no utilizados para obtener tokens de acceso en nombre de usuarios que ya han sido eliminados. Esto puede conducir a un acceso no autorizado a recursos y servicios sensibles, supeditado a los ámbitos originalmente autorizados para el código de autorización comprometido."
