CVE-2026-16606

Estado: AplazadaCrítica (9.3)—

A vulnerability in Fujitsu Software Linux openFT and Fujitsu Software Oracle Solaris openFT before version 12.1D00 allows for unauthenticated remote code execution (pre-auth RCE) on GNU/Linux or Oracle Solaris. The Fsas Technologies PSIRT obtained that intelligence internally and covers the CVE beyond its CNA scope under existing agreement with Fujitsu Germany.

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.

Vector CVSS AV:N/PR:N/UI:N indica explotación remota sin autenticación (T1190). RCE pre-autenticación implica ejecución de código arbitrario (T1059) sobre los sistemas afectados.

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.
