CVE-2025-64100

CKAN is an open-source DMS (data management system) for powering data hubs and data portals. Prior to 2.10.9 and 2.11.4, session ids could be fixed by an attacker if the site is configured with server-side session storage (CKAN uses cookie-based session storage by default). The attacker would need to either set a cookie on the victim's browser or steal the victim's currently valid session. Session identifiers are now regenerated after each login. This vulnerability has been fixed in CKAN 2.10.9 and 2.11.4

Summary		(es) CKAN es un DMS (sistema de gestión de datos) de código abierto para impulsar centros de datos y portales de datos. Antes de 2.10.9 y 2.11.4, los IDs de sesión podían ser fijados por un atacante si el sitio está configurado con almacenamiento de sesión del lado del servidor (CKAN utiliza almacenamiento de sesión basado en cookies por defecto). El atacante necesitaría establecer una cookie en el navegador de la víctima o robar la sesión actualmente válida de la víctima. Los identificadores de sesión ahora se regeneran después de cada inicio de sesión. Esta vulnerabilidad ha sido corregida en CKAN 2.10.9 y 2.11.4.
