CVE-2026-76327
Full vulnerability record from the local CVENow database.
Description
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, and Splunk Secure Gateway versions below 3.10.9, 3.9.23, and 3.8.70, an unauthenticated user could trick a user who holds the "admin" or "sc_admin" Splunk roles into opening a crafted Splunk Web Uniform Resource Locator (URL). The resulting dashboard searches could run arbitrary Search Processing Language (SPL) commands with the permissions available to the affected user. The commands could expose all relevant data available to that user and affect search results or lookup data. The vulnerability is possible because Splunk Secure Gateway dashboards do not correctly neutralize caller-supplied values before using them in dashboard searches. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The unauthenticated user should not be able to exploit the vulnerability at will.

"value": "En las versiones de Splunk Enterprise anteriores a 10.4.2, 10.2.6, 10.0.9 y 9.4.14, y en las versiones de Splunk Secure Gateway anteriores a 3.10.9, 3.9.23 y 3.8.70, un usuario no autenticado podría engañar a un usuario que posee los roles de Splunk ’admin’ o ’sc_admin’ para que abra un Uniform Resource Locator (URL) de Splunk Web manipulado. Las búsquedas del panel de control resultantes podrían ejecutar comandos arbitrarios de Search Processing Language (SPL) con los permisos disponibles para el usuario afectado. Los comandos podrían exponer todos los datos relevantes disponibles para ese usuario y afectar los resultados de búsqueda o los datos de consulta. La vulnerabilidad es posible porque los paneles de control de Splunk Secure Gateway no neutralizan correctamente los valores proporcionados por el llamador antes de usarlos en las búsquedas del panel de control. La vulnerabilidad requiere que el atacante realice phishing al usuario afectado engañándolos para que inicien una solicitud dentro de su navegador. El usuario no autenticado no debería poder explotar la vulnerabilidad a voluntad."
