CVE-2026-78319

Estado: AplazadaCrítica (9.3)—

A service running on the affected products contains a potential Time-of-Check Time-of-Use (TOCTOU) race condition. An unauthenticated remote attacker could exploit this race condition to bypass intended security controls. This may result in the execution of unauthorized code.

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 muestra acceso en red sin autenticación (AV:N/PR:N/UI:N) con confidencialidad, integridad y disponibilidad altas. TOCTOU permite bypasear controles de seguridad y ejecutar código no autorizado remotamente. T1190 es la explotación; T1059 es el impacto derivado ('execution of unauthorized

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.
