CVE-2025-20320

Estado: AnalizadaAlta (7.3)—

In Splunk Enterprise versions below 9.4.3, 9.3.5, 9.2.7 and 9.1.10, and Splunk Cloud Platform versions below 9.3.2411.107, 9.3.2408.117, and 9.2.2406.121, a low-privileged user that does not hold the "admin" or "power" Splunk roles could craft a malicious payload through the `User Interface - Views` configuration page that could potentially lead to a denial of service (DoS).The user could cause the DoS by exploiting a path traversal vulnerability that allows for deletion of arbitrary files within a Splunk directory. The vulnerability requires the low-privileged user to phish the administrator-level victim by tricking them into initiating a request within their browser. The low-privileged user should not be able to exploit the vulnerability at will.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

UI:R + path traversal permitiendo eliminación de archivos arbitrarios: T1203 (ejecución en cliente requiere interacción). Impactos: DoS por eliminación de ficheros (T1499.004) e integridad comprometida (T1565.001).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

El usuario podría causar la denegación de servicio (DoS) explotando una vulnerabilidad de path traversal que permite la eliminación de archivos arbitrarios dentro de un directorio de Splunk. La vulnerabilidad requiere que el usuario con privilegios bajos suplante a la víctima con nivel de administrador, engañándola para que inicie una solicitud en su navegador. El usuario con privilegios bajos no debería poder explotar la vulnerabilidad a voluntad."
