Descriptions

In Splunk Enterprise and Universal Forwarder versions before 9.0, the Splunk command-line interface (CLI) did not validate TLS certificates while connecting to a remote Splunk platform instance by default. After updating to version 9.0, see Configure TLS host name validation for the Splunk CLI https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/EnableTLSCertHostnameValidation#Configure_TLS_host_name_validation_for_the_Splunk_CLI to enable the remediation. The vulnerability does not affect the Splunk Cloud Platform. At the time of publishing, we have no evidence of exploitation of this vulnerability by external parties.

The issue requires conditions beyond the control of a potential bad actor such as a machine-in-the-middle attack. Hence, Splunk rates the complexity of the attack as High.

En las versiones de Splunk Enterprise y Universal Forwarder anteriores a la 9.0, la interfaz de línea de comandos (CLI) de Splunk no validaba por defecto los certificados TLS mientras se conectaba a una instancia remota de la plataforma Splunk. Después de actualizar a la versión 9.0, consulte Configurar la validación de nombres de host TLS para la CLI de Splunk https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/EnableTLSCertHostnameValidation#Configure_TLS_host_name_validation_for_the_Splunk_CLI para activar la corrección. La vulnerabilidad no afecta a la plataforma Splunk Cloud. En el momento de la publicación, no tenemos evidencia de la explotación de esta vulnerabilidad por partes externas. El problema requiere condiciones más allá del control de un potencial mal actor, como un ataque machine-in-the-middle. Por lo tanto, Splunk califica la complejidad del ataque como Alta
