Descriptions

Splunk Enterprise deployment servers in versions before 9.0 allow unauthenticated downloading of forwarder bundles. Remediation requires you to update the deployment server to version 9.0 and Configure authentication for deployment servers and clients (https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/ConfigDSDCAuthEnhancements#Configure_authentication_for_deployment_servers_and_clients). Once enabled, deployment servers can manage only Universal Forwarder versions 9.0 and higher. Though the vulnerability does not directly affect Universal Forwarders, remediation requires updating all Universal Forwarders that the deployment server manages to version 9.0 or higher prior to enabling the remediation.

Los servidores de implementación de Splunk Enterprise en versiones anteriores a 9.0, permiten una descarga no autenticada de paquetes de reenvío. La corrección requiere que actualice el servidor de implementación a versión 9.0 y que configure la autenticación para los servidores de implementación y los clientes (https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/ConfigDSDCAuthEnhancements#Configure_authentication_for_deployment_servers_and_clients). Una vez habilitada, los servidores de implantación sólo pueden administrar las versiones 9.0 y superiores de Universal Forwarder. Aunque la vulnerabilidad no afecta directamente a Universal Forwarders, la corrección requiere la actualización de todos los Universal Forwarders que el servidor de implementación administra a versión 9.0 o superior antes de habilitar la reparación
