Percentil entre todas las CVEs puntuadas: 12
Fecha de la puntuación: 6/10/2026

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.

ExplotaciónT1195 Supply Chain Compromiseinitial access85 %
Impacto principalT1553.006 Code Signing Policy Modificationdefense impairment80 %
Impacto secundarioT1059 Command and Scripting Interpreterexecution75 %

Firmware sin firmar permite forjar paquetes maliciosos (T1195 cadena suministro); con acceso admin remoto (PR:H, AV:N), el atacante instala código arbitrario (T1553.006 compromiso de firmware, T1059 ejecución).

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.
