CVE-2026-7770

Estado: AnalizadaAlta (8.8)—

IBM i Access Family 1.1.5.0 through 1.1.9.12 IBM i Access Client Solutions (ACS) is vulnerable to remote code execution when configured to listen for requests from IBM i Navigator.

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 AV:N/PR:L indica acceso remoto con privilegios mínimos (T1210). RCE en ACS permite ejecución remota de comandos (T1059) y potencial acceso a credenciales del cliente (T1078).

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.
