CVE-2026-76147

Estado: AplazadaMedia (5.9)—

A path traversal (ZIP Slip) vulnerability caused by insufficient authorization and integrity verification in the agent upgrade feature of Genian NAC/ZTNA allows a remote attacker to execute arbitrary 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 AV:N con PR:H permite explotación remota de servicio tras autenticación; path traversal en actualización del agente permite ejecución de código arbitrario (T1059.007) y acceso a datos locales (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.
