Descriptions

Splunk Enterprise peers in Splunk Enterprise versions before 9.0 and Splunk Cloud Platform versions before 8.2.2203 did not validate the TLS certificates during Splunk-to-Splunk communications by default. Splunk peer communications configured properly with valid certificates were not vulnerable. However, an attacker with administrator credentials could add a peer without a valid certificate and connections from misconfigured nodes without valid certificates did not fail by default. For Splunk Enterprise, update to Splunk Enterprise version 9.0 and Configure TLS host name validation for Splunk-to-Splunk communications (https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/EnableTLSCertHostnameValidation) to enable the remediation.

Los peers de Splunk Enterprise en Splunk Enterprise versiones anteriores a 9.0 y Splunk Cloud Platform versiones anteriores a 8.2.2203 no comprueban los certificados TLS durante las comunicaciones de Splunk a Splunk por defecto. Las comunicaciones entre pares de Splunk configuradas apropiadamente con certificados válidos no eran vulnerables. Sin embargo, un atacante con credenciales de administrador podía añadir un peer sin un certificado válido y las conexiones desde nodos configurados inapropiadamente sin certificados válidos no fallaban por defecto. Para Splunk Enterprise, actualice a versión 9.0 de Splunk Enterprise y configure la comprobación del nombre de host TLS para las comunicaciones entre Splunk (https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/EnableTLSCertHostnameValidation) para habilitar la corrección
