Users are recommended to upgrade to 4.2.1 version that includes the fix for this issue.\n\nAccess / authorization required: No Hive credentials, SAML IdP login, or knowledge of the server signing secret is required. The attacker only needs network reachability to the HiveServer2 HTTP port (typically /cliservice), directly or through a reverse proxy such as Apache Knox that forwards unauthenticated requests to HS2. The instance must have SAML authentication enabled in HTTP mode. Deployments where Knox handles SSO and HiveServer2 uses LDAP/Kerberos (not native SAML mode) are not affected by this specific issue."}, {"lang": "es", "value": "Una vulnerabilidad de autenticaci\u00f3n impropia en la validaci\u00f3n de tokens portadores SAML de HiveServer2 en Apache Hive 4.0.0 hasta 4.2.0 (y ramas posteriores no publicadas) en despliegues que usan transporte HTTP con hive.server2.authentication=SAML permite a un atacante de red no autenticado autenticarse como un usuario Hive arbitrario y obtener una sesi\u00f3n de HiveServer2 autenticada a trav\u00e9s de un token 'Authorization: Bearer' falsificado enviado al endpoint HTTP /cliservice. Se recomienda a los usuarios actualizar a la versi\u00f3n 4.2.1 que incluye la correcci\u00f3n para este problema.\n\nAcceso / autorizaci\u00f3n requerida: No se requieren credenciales de Hive, inicio de sesi\u00f3n de SAML IdP, ni conocimiento del secreto de firma del servidor.
