CVE-2026-16832

Estado: AnalizadaAlta (8.4)—

IBM Power Systems Firmware FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW950.00 through FW950.H2 is affected by a vulnerability in the FSP management network protocol. An attacker with authenticated HMC administrator access can execute arbitrary code on the service processor, giving full control over the managed system, resulting in a confidentiality, integrity, and availability impact.

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.

AV:A y PR:H indican acceso de red adyacente con privilegios elevados (admin HMC); ejecución de código arbitrario en el procesador de servicios con control total del sistema (confidencialidad, integridad, disponibilidad comprometidas).

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.
