Descripción

*** Pendiente de traducción *** Incorrect implementation of JWT/OAuth authentication in Impala executors in Apache Impala versions up to and including 4.5.2 which allows attacked to access resources served by the executor&amp;#39;s webserver when that webserver is configured to accept JWT/OAuth tokens.  Bearer token (JWT) signatures are not validated resulting in the webserver accepting any valid JWT.<br /> Users are recommended to either disable JWT/OAuth auth for Impala executors or upgrade to version 4.5.3, which fixes this issue.
