CVE-2026-12579

Estado: AplazadaAlta (7.4)—

AS228T with Authentication Bypass Vulnerability

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/PR:N permite T1190 (aplicación expuesta sin privilegios). CWE-288 (autenticación débil) habilita T1078 (acceso con credenciales válidas o bypass). Impacto secundario T1565 por I:H (integridad comprometida).

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.
