CVE-2026-18848
Estado: AnalizadaAlta (8.3)—
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 ASMI web interface. An attacker who can lure a logged-in ASMI administrator to visit a crafted web page can, under specific conditions, silently perform administrative actions on the FSP on behalf of that administrator, resulting in a confidentiality, integrity, and availability impact to the managed system.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:H
- Puntuación base: 8.3
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.15%
- Percentil entre todas las CVEs puntuadas: 4
- Fecha de la puntuación: 5/10/2026
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.
- Explotación
T1203Exploitation for Client Executionexecution95 % - Impacto principal
T1185Browser Session Hijackingcollection85 % - Impacto secundario
T1499.004Application or System Exploitationimpact70 % - Impacto secundario
T1565.001Stored Data Manipulationimpact75 %
Vector CVSS con UI:R requiere interacción del usuario (visitar página web preparada). CWE-352 es CSRF; el atacante realiza acciones administrativas en el FSP (impersonación de sesión), alterando configuración y disponibilidad del sistema Power.
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.
