CVE-2026-46447

Estado: ModificadaAlta (7.7)—

OpenStack Ironic before 35.0.2 allows Boot Script Injection of an iPXE script if the attacker can set node.driver_info or node.instance_info.

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 privilegios (PR:L) a servicio OpenStack Ironic (red). Inyección de script iPXE en boot permite secuestro de flujo de ejecución y ejecución de comandos arbitrarios.

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.
