CVE-2026-76142

Estado: AplazadaCrítica (9.3)—

Insufficient authentication and access control on the internal-only IPC SOAP endpoint of the Genian NAC/ZTNA policy server allows an unauthenticated attacker to invoke internal functions

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.

Explotación de aplicación expuesta (SOAP endpoint sin autenticación, AV:N PR:N) que permite acceso no autenticado a funciones internas, derivando en escalada de privilegios lógicos (T1078) y potencial ejecución de comandos remota en el servidor de políticas.

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.
