Descriptions

In Splunk Enterprise versions below 9.4.3, 9.3.5, 9.2.7, and 9.1.10, and Splunk Cloud Platform versions below 9.3.2411.104, 9.3.2408.113, and 9.2.2406.119, an unauthenticated attacker could send a specially-crafted SPL search command that could trigger a rolling restart in the Search Head Cluster through a Cross-Site Request Forgery (CSRF), potentially leading to a denial of service (DoS). The vulnerability requires the attacker to phish the administrator-level victim by tricking them into initiating a request within their browser. The attacker should not be able to exploit the vulnerability at will. See [How rolling restart works](https://docs.splunk.com/Documentation/Splunk/9.4.2/DistSearch/RestartSHC) for more information.

En las versiones de Splunk Enterprise anteriores a 9.4.3, 9.3.5, 9.2.7 y 9.1.10, y Splunk Cloud Platform anteriores a 9.3.2411.104, 9.3.2408.113 y 9.2.2406.119, un atacante no autenticado podría enviar un comando de búsqueda SPL especialmente manipulado que podría desencadenar un reinicio progresivo en el clúster del cabezal de búsqueda a través de un Cross-Site Request Forgery (CSRF), lo que podría provocar una denegación de servicio (DoS). La vulnerabilidad requiere que el atacante suplante de identidad (phishing) a la víctima de nivel de administrador engañándola para que inicie una solicitud dentro de su navegador. El atacante no debería poder explotar la vulnerabilidad a voluntad. Consulte [Cómo funciona el reinicio continuo](https://docs.splunk.com/Documentation/Splunk/9.4.2/DistSearch/RestartSHC) para obtener más información.
