      "value": "LDAP injection vulnerability in Apache Zeppelin. ActiveDirectoryGroupRealm constructed LDAP search filters without escaping user-controlled input, allowing an authenticated attacker to inject LDAP filter syntax through the user-search endpoint                   and potentially expose directory information. The role-lookup path was also affected after successful LDAP authentication. This issue affects Apache Zeppelin versions 0.6.0 through 0.12.0. Users are recommended to upgrade to version 0.12.1, which                   fixes this issue."

ActiveDirectoryGroupRealm construyó filtros de búsqueda LDAP sin escapar la entrada controlada por el usuario, permitiendo a un atacante autenticado inyectar sintaxis de filtro LDAP a través del endpoint de búsqueda de usuarios y potencialmente exponer información del directorio. La ruta de búsqueda de roles también se vio afectada después de una autenticación LDAP exitosa. Este problema afecta a las versiones de Apache Zeppelin 0.6.0 a 0.12.0. Se recomienda a los usuarios actualizar a la versión 0.12.1, que corrige este problema."
