CVE-2026-9259

Estado: AnalizadaAlta (7.1)—

Improper validation of server certificates in Canon EOS Network Setting Tool Version 1.5.0 or earlier

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:N + UI:P + CWE-295 (validación inadecuada de certificados) indica explotación en cliente con interacción (T1203). Falta de validación de certificados permite ataque MITM (T1557) e intercepción de datos (T1005).

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.
