Descriptions

Apache Hive before 3.1.3 "CREATE" and "DROP" function operations does not check for necessary authorization of involved entities in the query. It was found that an unauthorized user can manipulate an existing UDF without having the privileges to do so. This allowed unauthorized or underprivileged users to drop and recreate UDFs pointing them to new jars that could be potentially malicious.

Las operaciones de función "CREATE" y "DROP" de Apache Hive versiones anteriores a 3.1.3, no comprueban la autorización necesaria de las entidades implicadas en la consulta. Se ha encontrado que un usuario no autorizado puede manipular una UDF existente sin tener los privilegios para hacerlo. Esto permitía a usuarios no autorizados o poco privilegiados soltar y volver a crear UDFs que apuntaban a nuevos tarros que podían ser potencialmente maliciosos
