CVE-2026-20297

Estado: AnalizadaAlta (7.2)—

In Splunk Enterprise versions below 10.4.1, 10.2.5, 10.0.8, 9.4.13, and 9.3.14, and Splunk Cloud Platform versions below 10.5.2605.0, 10.4.2604.6, 10.2.2510.18, and 10.1.2507.24, a user who holds a role that contains the `edit_local_apps` and `install_apps` capabilities could cause a legitimate app installation to write files outside the intended app directory, into `$SPLUNK_HOME/etc/` and its subdirectories.<br><br>The vulnerability is caused by a path traversal in the app installation workflow, which does not restrict the installation path to the intended app directory.

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.

Acceso remoto con PR:H (privilegios requeridos) en servicios Splunk. Path traversal (CWE-22) permite escribir fuera del directorio de app, manipulando archivos en $SPLUNK_HOME/etc con impacto en integridad y escalada.

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.
